Statement 1001

Warning

Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018

This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that

Warning

the protective device is rated not greater than:

120 VAC, 15A (240 VAC, 10A international) Statement 1005

To prevent accidental discharge in the event of a power line cross, route on-premise wiring away

Warning

from power cables and off-premise wiring, or use a grounded shield to separate the on-premise

wiring from the power cables and off-premise wiring. A power line cross is an event, such as a

lightning strike, that causes a power surge. Off-premise wiring is designed to withstand power line

crosses. On-premise wiring is protected from power line crosses by a device that provides

overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring is in close proximity

to, or not shielded from, the off-premise wiring or power cables during a lightning strike or power

surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment,

and nearby personnel. Statement 338
