CS3 Three Phase SSR Quick Start Manual

 0037-75554 (PK528)

This manual is intended to provide only the basic installation and operation instruc-

tions for the CS3 Three Phase Solid State Relay. Please refer to manual PK522, for 

complete installation & operation details. The most current revision of PK522 may be

 1. IMPORTANT SAFEGUARDS

ELECTRIC SHOCK HAZARD: Read and understand all instructions before 

installing, servicing or operating this controller. Failure to do so could 

result in equipment or property damage as well as personal injury and 

even death.

HIGH VOLTAGE is used in the operation of this equipment. DEATH ON 

CONTACT may result if personnel fail to observe safety precautions. 

Learn the areas containing high-voltage connections when installing or 

operating this equipment.

Be careful not to contact high-voltage connections when installing or 

operating this equipment. Before working inside the equipment, turn 

power off and ground all points of high voltage potential before touch-

ing.

ELECTRIC SHOCK HAZARD. Any installation involving control equip-

ment must be performed by a qualified person and must be effectively 

grounded in accordance with the National Electrical Code to eliminate 

shock hazard. 

The Owner/Installer must provide all necessary safety and protection 

devices and follow all current electrical wiring standards and regula-

tions. Failure to do so may compromise the integrity of the controller 

and/or cause product failure resulting in a safety risk to operational 

service and personnel.

This controller utilizes a heat sink which is designed to cool the unit 

during operation. Under no circumstance should air flow around the 

controller be compromised in any way. Failure to do so may result in the 

overheating of the controller, product failure, product temperatures and 

even fire.

During continuous operation, the heat sink can reach a very high tem-

peratures, and keeps a high temperature even after the unit is turned 

off due to its high thermal inertia.
Higher voltages may be present. DO NOT work on the power section 

without first disconnecting electrical power to the panel. Failure to do 

so could result in serious injury or death.

 2. INSTALLATION - MECHANICAL

To ensure proper performance, maximum safety and reliability, it is essential to install 

the unit correctly. This includes proper mounting, spacing, hardware and wiring. See 

below:
1.  Maximum surrounding air temperature is 40°C in “Open Type Equipment” which 

is suitable for use in pollution degree 2.

2.  Install the unit vertically (max 10° inclination from vertical axis).

3. Spacing:

  –Min. vertical distance between unit and panel wall: 3.9” (100 mm)

  –Min. horizontal distance between unit and panel wall: 0.8” (20 mm)

  –Min. vertical distance between adjacent power control units: 11.8” (300 mm)

  –Min. horizontal distance between adjacent power control units: 0.8” (20 mm)
