CHECKPOINTS WHEN PERFORMING ON-SITE SER-
VICE
NEC brand products are extensively tested before shipping, to ensure that all applicable
safety standards are met, in order to protect the customer and customer engineer (hereaf-
ter called the CE) from the risk of injury. However, in daily use, any electrical equipment
may be subject to parts wear and eventual failure. In order to maintain safety and reliability,
the CE must perform regular safety checks.
1. Power Supply
• Using parts not specified by NEC.
WARNING: Wall Outlet
• Check that mains voltage is as specified. Plug the power
cord into the dedicated wall outlet with a capacity greater
than the maximum power consumption.
If excessive current flows in the wall outlet, fire may
result.
• If two or more power cords can be plugged into the wall
outlet, the total load must not exceed the rating of the wall
outlet.
If excessive current flows in the wall outlet, fire may
result.
WARNING: Power Plug and Cord
• Make sure the power cord is plugged in the wall outlet
securely.
Contact problems may lead to increased resistance,
overheating, and the risk of fire.
DANGER: PROHIBITED ACTIONS
