CVX050/100 Surge Protective Device
Installation and Operation
EATON

1.0 Introduction
This manual describes how to install a CVX050 or CVX100 Surge
Protective Device (SPD) in parallel (shunt) across the electrical sup-
ply of the following types of electrical systems:
•
Single Phase
•
Split Phase
•
3-Phase Wye (Star)
•
3-Phase Delta (no Neutral
•
Direct Current (DC))
The SPD is designed to be installed on service entrance, branch
panels, and/or individual equipment disconnects, and functions to
protect sensitive electronic equipment from damaging voltage tran-
sients. The connecting wires do not carry supply current. Instead,
they carry only short- duration currents that are associated with a
transient event.
These instructions do not cover all details, variations, or combina-
tions of the equipment, its storage, delivery, installation, checkout,
safe operation, or maintenance. If you require further information
regarding a particular application or installation that is not covered in
this manual, please contact Eaton’s Power Quality Technical Support
at 1-800-809-2772.
1.1 Safety Precautions
A licensed/qualified electrician must complete all instructions
described in this manual in accordance with the U.S. National
Electrical Code, state and local codes, or other applicable country
codes. All electrical codes supersede these instructions.
WARNING
IMPROPER INSTALLATION CAN CAUSE DEATH, INJURY, AND/OR EQUIP-
MENT DAMAGE. FOLLOW ALL WARNINGS AND CAUTIONS. COMPLETELY
READ AND UNDERSTAND THE INFORMATION IN THIS INSTRUCTION MAN-
UAL BEFORE ATTEMPTING TO INSTALL OR OPERATE THIS EQUIPMENT.
IMPROPER WIRING COULD CAUSE DEATH, INJURY, AND/OR EQUIPMENT
DAMAGE. ONLY LICENSED/QUALIFIED ELECTRICIANS WHO ARE TRAINED
IN THE INSTALLATION AND SERVICE OF ELECTRICAL DEVICES ARE TO
INSTALL THIS EQUIPMENT.
USE APPROPRIATE SAFETY PRECAUTIONS AND EQUIPMENT FOR ARC
FLASH PROTECTION.
DURING NORMAL OPERATION, HAZARDOUS VOLTAGES ARE PRESENT
INSIDE THE SPD.
WHEN INSTALLING THE SPD, FOLLOW ALL SAFE WORK PRACTICES TO
AVOID ELECTRICAL SHOCK.
CAUTION
DO NOT PERFORM A HIGH-POT TEST WITH THE SPD CONNECTED TO THE
ELECTRICAL SYSTEM. FAILURE TO DISCONNECT THE SPD DURING A HIGH-
POT TEST WILL RESULT IN DAMAGE TO THE SPD.
AFTER INSTALLATION THIS DEVICE IS NOT REPAIRABLE AND CONTAINS
NO SERVICABLE PARTS. IF THE UNIT SHOULD MALFUNCTION OR NEEDS
REPLACED CONTACT A QUALIFIED ELECTRICIAN OR EATON CARE AT 877
ETN CARE (877-386-2273).
1.2 Catalog Numbering System
2.0 Installation
Refer to Section 1.2 and look at the label on the SPD to verify that
the SPD’s voltage rating and wiring configuration matches that of
the electrical system. Use a voltmeter to measure the system’s line
voltage to ensure that the correct model of SPD is being installed.
Damage to the SPD may result if it is connected to an electrical sys-
tem of a higher voltage or different wiring configuration.
2.1 Mounting
The SPD can be mounted directly to the electrical panel, or mounted
to a wall using the enclosure’s internal mounting holes or optional
external mounting feet.
IMPORTANT
• CHOOSE A MOUNTING LOCATION FOR THE SPD THAT PROVIDES THE
SHORTEST AND STRAIGHTEST POSSIBLE WIRING (LEAD LENGTH) FROM
THE SPD TO THE ELECTRICAL SYSTEM CONNECTIONS. EXCESSIVE LEAD
LENGTH AND SHARP BENDS WILL DEGRADE SPD PERFORMANCE.
• IF THE ELECTRICAL SYSTEM USES AN ISOLATED GROUND, THE SPD MUST
BE ISOLATED FROM GROUND USING INSULATED CONDUIT FITTINGS.
• WHEN USING CONDUIT, AVOID USING 90° ELBOWS AND KEEP THE
CONDUIT RUN AS SHORT AND STRAIGHT AS POSSIBLE.
