Installation Precautions (continued)
■
Ensure the power source circuits are properly grounded, then use the
power cord supplied with the switch to connect it to the power source.
If your installation requires a different power cord than the one supplied
with the switch and power supply, be sure the cord is adequately sized
for the switch’s current requirements. In addition, be sure to use a power
cord displaying the mark of the safety agency that defines the regulations
for power cords in your country. The mark is your assurance that the
power cord can be used safely with the switch and power supply.
■
When installing the switch, note that the AC outlet should be near the
switch and should be easily accessible in case the switch must be
powered off.
■
Ensure the switch does not overload the power circuits, wiring, and over-
current protection. To determine the possibility of overloading the supply
circuits, add together the ampere ratings of all devices installed on the
same circuit as the switch and compare the total with the rating limit for
the circuit. The maximum ampere ratings are usually printed on the
devices near the AC power connectors.
■
Do not install the switch in an environment where the operating ambient
temperature might exceed 40
°
C (104
°
F).
■
Allow three to four inches of space around the sides and back of the
switch to make sure the air flow for the switch is not restricted.
