Wiring Requirements
ATTENTION
Before connecting the hardware, follow these important wiring safety precautions:
Disconnect power source
Do not install or wire this unit or any attached devices with the power connected. Disconnect the
power before installation by removing the power cord before installing and/or wiring your unit.
Follow maximum current ratings
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.
Use caution - unit may get hot
The unit will generate heat during operation, and the casing may feel hot to the touch. Take care
when handling unit. Be sure to leave adequate space for ventilation.
The following guidelines will help ensure trouble-free signal communication:
z Use separate paths to route wiring for power and devices to avoid interference. Do not run
signal or communication wiring and power wiring in the same wire conduit. The rule of
thumb is that wiring that shares similar electrical characteristics can be bundled together.
z If power wiring and device wiring paths must cross, make sure the wires are perpendicular at
the intersection point.
z Keep input wiring and output wiring separate.
z Label all wiring to each device in the system for easier testing and troubleshooting
