Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your UC-7420/7410.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
Temperature Caution!
Be careful when handling UC-7420/7410. When plugged in, UC-7420/7410’s internal
components generate heat, and consequently the outer casing may feel hot to the touch.
You should also observe the following common wiring rules:
y Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire
conduit. To avoid interference, wires with different signal characteristics should be routed
separately.
