Although I know it is not recommended, I have no choice but to plug my AC into a surge protected power bar/extension. I have done so for the last 2 summers, no problem. I take out my AC to install, last night, irt runs 10 minutes , then shuts off. The surge bar gets reset and it starts again, for 10 minutes.... I changed my power bar thinking that may be it. It is still happening! Is it do-able? Do I just need a higher 'jules'? It is do-able, I,ve done it. However, I can't say it is the AC , alone the problem, I've used it 3 summers. It has always been stored in a closet in the house. Never been dropped or anything. Help! We're havuing a heat wave here! THanks.

Common Causes of Lightning Strikes

• Outdoor network cables or power cables are routed overhead.
• A switch is deployed outdoors but is not properly grounded.

Damages of Lightning Strikes

• If power cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn the power supplies.
• If network cables of a switch are routed overhead in an outdoor environment, lightning strikes may burn interfaces of the switch.

When a switch undergoes lightning strikes, overvoltage is induced by lightning on network cables and transmitted to interior of the chassis. The surge protection measures, such as lightning rod and chassis grounding cannot prevent the damage. Therefore, surge protectors or surge protection circuits are recommended.

Surge Protector Use Precautions Take the following precautions to protect a switch from lightning:

• Ensure that the ground cable is connected to a ground bar or a ground point on the cabinet.
• Avoid routing cables overhead in an outdoor environment. Bury cables underground or route them in steel tubes.
• To protect network interfaces against lightning, use 8-line surge protectors (or Huawei certified 4-line surge protectors).
• When installing a network interface surge protector, connect the IN end to terminals and the OUT end to network interfaces of the switch.

If a fixed switch is installed in a network box, follow these instructions:

• Connect the ground cables of the switch and surge protectors to the ground bar in the network box.
• The maximum length of a ground cable cannot exceed 40 cm, and a length of smaller than 15 cm is recommended.
• If the network box is located outdoors and power cables are routed aerially over a long distance (more than 300 m) to the network box, it is recommended that you install a power supply surge protector in the network box. The decoupled power cable must be at least 3 m long

If your Brother machine does not appear to have power,then check whether or not the date and time appear on your Brother machine's LCD. If anything is displayed on your Brother machine's LCD, then it is most likely receiving power.If your Brother machine's LCD is blank, continue to Step 2.
Verify the Brother machine's power cord is connected securely to the power outlet. If you are using a surge protector, extension cord, or power switch, disconnect it and plug the Brother machine directly into the wall outlet.
Please note Brother strongly recommends that you connect your machine to a surge protector.Because To protect your investment against power surges and lightning,
In particular, we suggest that you use a surge protector that is compatible with both standard A.C. power cords and telephone line cords. Surge protectors equipped with telephone jacks will assist in insulating your machine from any power surge that might travel through a telephone line.
If the Brother machine is turned OFF, its LCD will be blank. Please make sure the Brother machine is powered ON by pressing and holding the On/Off or Power Save key. This key is located in the upper-right corner of the control panel.
If your Brother machine's LCD is still blank, connect it to a completely different, known working power outlet. If the Brother machine powers up, then the problem is related to the original outlet.
-OR-
Confirm the power outlet is working by plugging another known working device (a lamp, radio, etc.) directly into the same outlet. If the other device does not work, the problem is related to that power outlet. If a wall switch controls the outlet, verify that the switch is ON.
If your Brother machine still will not power on, please contact Brother Customer Service.

This sounds possibly like a power related issue. If you are using a simple power strip to plug into, consider replacing it with an Uninterruptible Power Supply (aka Battery Backup, UPS). AC power related issues can cause screen waviness or shaking. Be sure to obtain the proper capacity unit for your needs. These units are rated in Volt AMPS and come in sizes from 300VA to 1500VA in the consumer product line. APC, Belkin, Triplite, CyberPower are some popular brands. The VA capacity to choose should be considered over price alone. Buying the cheapest one vs the right capacity can result in not having a unit capable of protecting your devices plugged into it. Understand these have 2 primary functions,
1. surge-protection
2. battery backup during a power related problem
There are 2 different banks of receptacles on these units.
1. Some for surge protection AND battery backup
2. Some for surge protection ONLY
Your computer would be plugged into the surge AND battery backup receptacles. When a power related incident occurs, the unit quickly switches the devices plugged into these receptacles off of AC power to the batteries, until the power issue is resolved. The time on battery is limited based on the VA capacity mentioned earlier in this solution. So buying the largest VA capacity unit you can afford will simply give you more available time on battery before the batteries are exhausted and must be recharged. On the other hand buying the smallest VA unit could result in an immediate and unexpected shut down of the computer if a power related issue occurs and the battery backup cannot handle the devices plugged into it. NEVER use these units for battery backup of Laser Printers or other high curent devices. These can destroy the battery backup.
I hope this helps with your screen issue.

although power surge can trigger activations of protection circuits,

there are at times, damage is done before it is activated.

• Check first for low power supply regulators,

then check for possible output stage failure.

let me know if you need further assistance!

Try this approach:
1. Remove the power adapter from the printer. The power adapter is the black box where the power cord is plugged in at the back of the printer.2. Disconnect the power cord from the power source.3. Reconnect the power cord directly to the power outlet in the wall. Bypass any surge devices or power outlets.4. Re-plug the power adapter into the printer.5. If the printer won't automatically power on, press the power button on the printer operator panel.
I hope this helps.
Should the problem continue, please contact Lexmark Technical Support Center for additional assistance.

The best thing I can tell you is, that Danby does not recommend it. Even an extension cord is not recommended, unless it is a 14 gauge and no longer that 6 feet.

Several questioners in the past, have used a surge protect power bars and ended up frying the electronics of their AC units.

But, in the end, it's up to you.

1. Connect the handset.
Connect the curled handset cord to the bottom of the handset and to the left side of the machine.
2. Connect the power cord.
3. Connect the telephone line.
Connect one end of the telephone line cord to the jack labeled LINE on the left side of the machine. Connect the other end to a modular wall jack.
WARNING
 This machine must be grounded using a three-prong plug.
 Since the machine is grounded through the power outlet, you can protect yourself from potentially hazardous electrical conditions on the telephone line by keeping the power to your machine on when you connect it to a telephone line. When you want to move your machine, protect yourself by disconnecting the telephone line first, and then the power cord.
 Lightning and power surges can damage this product! We recommend that you use a quality surge protection device on the AC power line as well as on the telephone line, or unplug the lines during a lightning storm.

Yes sure. No problem. As the battery backup (UPS) has its own surge protection for the output anyway. :)

First, most of the UPS sensitivity can be adjusted. Setting a higher sensitivity will make the UPS compensable much faster if the current goes to high to too low thus always providing a good power quality to the equipments. For example, on a BackUPS RS the low level can be configured from 94V to 104V and the high level from 126V to 136V. An entry-level UPS such as the APC BackUPS ES will switch to battery mode as soon as the power goes out of the sensitivity range. On the other hand, a high-end UPS for workstation like the APC BackUPS RS has a feature called Automatic Voltage Regulation (AVR) that compensate at some extent without requiring the battery; this makes the battery last longer before needing to be replaced.

Second, most of the UPS have "Battery Protected" and "Surge only" outlets. Make sure that the computers are connected to the "Battery Protected". The "Surge only" outlets will only protect from parasites or surges like a thunder storm. They should be used for less important stuff like a desk lamp or devices with high demand peek such as a laser printer.

Third, the use of a power bar connected to the "Battery Protected" side should not have any impact as long as it is not overloading the UPS. Personnaly, I have a power bar connected to both my UPS.
