Introduction What Equipment Needs Power Conditioning?
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 power conditioner.
Sizing Information
The rating label of your ONEAC CDR45I Series 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 on any of the three phases.
Your ONEAC CDR45I Series Power Conditioner can operate even with a 100%
unbalanced load.
Operating Environment
Clean room The ONEAC CDR45I Series Power Conditioner is intended for operation in a
clean room environment. Note that the conditioner incorporates two fans for air
circulation. These fans must not be impeded to maintain full circulation. The
finish on the conditioner is selected for minimum dusting.
Audible noise The ONEAC CDR45I Series Power Conditioner produces less than 45 dBA of
audible noise measured at a distance of one meter from the center of the front
door.

Installation
Principle of Operation
The following brief description of the ONEAC CDR45I Series Power
Conditioner’s principle of operation is provided to assist in the proper
installation and operation of your power conditioner.
Interconnections and Operations:
1. AC power is supplied to the power conditioner by connection to the input
terminal block. When AC power is supplied to this terminal block via the
service panel circuit breaker, the Input Power ON LED is illuminated.
2. Three phase AC power is connected from the terminal block to the main
input circuit breaker. The input circuit breaker for this product utilizes
modular current trip rating plugs which are inserted or plugged into a single
molded case circuit breaker frame. An undervoltage release accessory is
installed in the input breaker as a means of control.
3. A separate multi-tapped primary, 24 Vac secondary, transformer is utilized
for power control, and supplied from the input terminal block (L1 and L2).
The primaries of this transformer are fuse protected (2A, 600 V rating). The
secondary of this transformer is also fuse protected (1A, 250 V rating).
4. The 24 Vac control circuit energizes the undervoltage release accessory
within the main input circuit breaker when the Emergency Mains Off
(EMO) circuit is closed. An external connection for the EMO circuit is
provided by means of a circular plastic connector (CPC) located on the
lower right back panel above the convenience receptacles. The power
conditioner is shipped with a shorting plug secured to the panel mounted
CPC. The shorting plug has a wire jumper across pins 3 and 4 of the CPC. A
spare mating CPC is provided with the unit in the spares compartment to
allow for this shorting plug to be replaced with any series connected NC
contact string. (See “Emergency Mains Off” on page 26 for detailed
description of operation.)
5. In order to turn ON the main input circuit breaker, the EMO circuit must be
closed so that the undervoltage release accessory is energized.
ONEAC CDR45I Series Power Conditioner, Installation Guide, 913-521 Rev. A 15
Installation Principle of Operation
6. Pins 1 and 2 of the CPC provide the user with a pair of contacts that are
opened when the EMO circuit has been alarmed and are closed during
normal unit operation. (See “Emergency Mains Off” on page 26 for detailed
description of operation.)
7. The secondaries of the Mains transformer are connected to the Virtual
Kelvin Ground®.
8. When the main input circuit breaker is turned ON, power is applied to the
cooling fans, and the main output circuit breaker. When the main output
circuit breaker in turned ON, the Output Power ON LED is illuminated and
power is available at the output power block.
NOTE Proper input voltage configuration is achieved by performing the following
three independent steps:
• Selection of the correct rating plug for the desired input voltage.
• Selection of the correct tap configuration for the Mains transformer (T1).
• Selection of the correct tap configuration for the Control transformer (T2).
The power conditioner is originally shipped from the manufacturer configured
for 400 Vac input operation unless otherwise stated on the label attached to the
input power block.
