Connecting the Hardware 

 

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.
