Connect to Power
Your factory trained COATS
®
Service Technician should do the
final check to verify the power installation before connecting the
balancer to a power supply. Failure due to improper power con-
nection will void the warranty.
Connect the balancer to an appropriate electrical receptacle.
Refer to Figures 4 and 5, as well as Electrical Requirements on
page 1.
Note: If pedestrian or equipment traffic might damage the
standard power cord, power outlets must be enclosed in a race-
way on the floor or in an overhead drop.
Note: Electric outlets must be solidly connected. There should
be less than 1 Ω electrical resistance between the ground pin
and earth ground. The installer or electrical inspector must ver-
ify the outlet installation before connecting the balancer. Failure
due to improper power connection will void the warranty.
Note: The green wire in the cord is the grounding wire. Never
connect the green wire to a live terminal.
