6 CC/CCS Power Conditioner User Manual
Input Connections The input connection for standard models is
supplied as a NEMA plug on the end of a cord.
Some models are available with a hardwire
input connection. Hardwire models have a 1/2”
(13 mm) conduit connection with internal
terminal blocks enclosed within an attached
wiring box. An additional hardwire version is
available that utilizes a flat conduit landing
plate attached to the rear of the unit that will
accept
1/2 or 3/4 inch conduit.
Your ONEAC cord-connected, CC and CCS
Series power conditioners will meet your power
conditioning requirements without the need for
special grounds. Since the cord-connected
power conditioner is considered as utilization
equipment, a connection to the equipment
grounding conductor that conforms to the U.S.
National Electrical Code and your local
electrical codes through the input cord and plug
is all that is necessary. However, for hardwired
units or if you wish to connect the secondary
side grounded conductor (neutral) of the power
conditioner to a grounding electrode system
(local building steel, water pipes, made
electrodes, etc.) you can do so by connecting a
grounding electrode conductor to the #10-32 x
3/4 inch stud referred to as the Environmental
Reference Ground
®
. This pressed-in stud is
electrically referenced to the secondary side
grounded conductor through an internal
bonding jumper.

1. Use a voltmeter to determine if voltage is
present in the branch circuit receptacle and
confirm that it is the same value as
specified on the power conditioner’s rating
label. The receptacle should meet the
requirements of the U.S. National
