What Equipment
Needs Power
Conditioning?
Only your electronic based equipment requires
conditioned power. Fans, air conditioners and
motors do not require power conditioning.
Placing fans, air conditioners, motors or other
noise generators between the conditioner and
the electronics introduces electrical interference
into the already conditioned power. In order to
minimize electrical noise, each piece of
equipment should be individually wired back to
the output of the ONEAC power conditioner.
Sizing Information
The rating label of your ONEAC power
conditioner lists the model’s current rating,
nominal input and output voltage and serial
number. The combined steady state RMS
current draw of all your equipment must not
exceed the power conditioner’s output current
rating.

Installation and
Operation
Unpacking and
Placement
Your ONEAC power conditioner is delivered in
a protective package. Upon arrival, inspect the
unit and the package for signs of damage. If
damage is detected, immediately contact the
freight company and ONEAC Technical
Services. You can reach ONEAC Technical
Services at 1-800-327-8801, option 3 or at
1-847-816-6000.
ONEAC recommends that your power
conditioner be left in the package during
handling. Remove the conditioner from the
package once it is as close as possible to its final
installation location.
The actual physical placement of the power
conditioner should be as close as possible to
your equipment. The power conditioner should
be installed inside the room containing your
equipment. Allow at least 2 inches (5.0 cm)
around all sides of the ONEAC power
conditioner. Do not allow the conditioner to be
installed where direct contact with water is
possible.

Installation and Operation
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.
Installation: Input Connections
Cord-connected models
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

Fuse Replacement
Output fuses are located above the conditioner's
receptacles or hardwire terminal connections.
The fuses protect the ONEAC power
conditioner from overload.
WARNING: Turn off the input and main output
circuit breakers on the power conditioner. Turn
off the power source supplying the power
conditioner at the service disconnect before
proceeding.

1. If a fuse blows, replace the blown fuse with
the same rating and type.
Fuse type: Midget (5AG).
Use a time delay fuse such as:
Bussmann FNW Series or Littelfuse
FLM Series
NOTE: Some models do not have fuses.
2. Follow the procedure in Verifying Your
Installation on page 4, as required.
Voltage Tap
Selection
Tap selection allows a permanent adjustment to
the voltage level. If the nominal output level is
not within the equipment manufacturer’s
suggested operating range, you can move the
power tap on the primary of the power
conditioner’s transformer as an adjustment.
NOTE: Tap selection should be completed by a
qualified electrician, only.
The purpose of tap selection is to configure the
input of the power conditioner to accept the
desired voltage or to correct for steady state

variances in nominal line voltage. The power
conditioner’s output voltage should be
monitored for a few days to determine the
normal output level before adjusting the voltage
by tap selection. Tap selection allows a
permanent adjust the conditioner's nominal
voltage level to correct a persistently high
voltage or low voltage condition.
Refer to Specifications on page 15, for the input
and output voltage for your model of ONEAC
power conditioner. The voltage specifications
as stated in the Specifications section are
standard when shipped directly from ONEAC.
NOTE: To operate at 208 Volts input and 208
Volts output use the same tap selection as 240
Volts input and 240 Volts output.
Voltage tap selection is available only on
selected models; CC2333, CC2338, CC2350,
CC2357, and all CCS models.
