Product information
Introduction
Service Information MN225017EN provides installation
instructions for Eaton's Cooper Power™ series CL-7 voltage
regulator control replacement assembly (CRA). Before
installing and operating this control, carefully read and
understand the contents of this manual.
For installation, operation and maintenance instructions
for the CL-7 voltage regulator control, refer to Service
Information MN225003EN CL-7 Voltage Regulator Control
Installation, Operation, and Maintenance Instructions for
information.
Read this manual first
Read and understand the contents of this manual and follow
all locally approved procedures and safety practices before
installing or operating this equipment. This control is used in
conjunction with a voltage regulator. Read and understand
the appropriate voltage regulator instruction manual before
operating this control.
Additional information
These instructions cannot cover all details or vari ations
in the equipment, procedures, or process described nor
provide directions for meeting every possible contin gency
during installation, operation, or maintenance. For additional
information, please contact your Eaton representative.
Acceptance and initial inspection
Each CRA is completely assembled, tested, and inspected
at the factory. It is in good condition when accepted by the
carrier for shipment. Upon receipt, inspect the shipping
container for signs of damage. Unpack the control and
inspect it thoroughly for damage incurred during shipment.
If damage is discovered, file a claim with the carrier
immediately.
Handling and storage
Be careful during handling and storage of the control to
minimize the possibility of damage. If the control is to be
stored for any length of time prior to installation, provide a
clean, dry storage area.

Description
Eaton's voltage regulator control replacement assembly
(CRA) is designed to be used on single-phase regulators
manufactured by Siemens
®
Corporation, General Electric
®
,
and Howard Industries
®
, as well as Eaton's Cooper Power
series type VR-32 voltage regulators.
The CRA kit utilizes the control signals common to all
voltage regulators. Designed into the CRA kits are control
cable connections and circuitry to enable an interface
between the CL-7 control and voltage regulators not
manufactured by Eaton.
IMPORTANT
CRA Applications
The CRA was designed for used on single-phase voltage
regulators that utilize the following circuits:
•
Control voltage or load-side voltage signal
•
Motor raise and lower circuits
•
Operations counter
•
Common or ground
•
CT current signal (optional)
•
Source-side voltage signal (optional)
•
Neutral light (optional)
•
Drag hand reset (optional)
All of the signals listed are necessary for operation of the
CRA unless otherwise noted as optional. Optional signals
are required in order to utilize all features of the CL-7
control.
