Important Safeguards
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 potential before touching them.
ELECTRIC SHOCK HAZARD: Any installation involving control equipment must be performed
by a qualified person and must be effectively grounded in accordance with the National
Electrical Code to eliminate shock hazard.

CS3 Three-Phase Solid State Relay
General
The CS3 Series of solid state relays are an ideal, low
cost power control solution for switching resistive
3-phase loads found applications in such as furnaces,
ovens, heat treating, injection molding, thermoforming,
press platens, commercial food equipment, semiconductor, lighting and drying, just to name a few.
Installation and Operation
The owner/installer must provide all necessary
safety and protection devices and follow all
current electrical wiring standards and regulations. Failure to do so may compromise the integrity of the controller and / or cause product
failure resulting in a safety risk to operational
and service 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.
The CS3 Series power controllers feature:
• Rugged, industrial design & touch-safe exterior
• Conservative, continuous service ratings at 40˚C
• Up to 3 x 55 Amps and up to 600 VAC
• AC and DC Voltage command signals
• Zero cross firing
• Easy terminal access via removable covers
• Integrated heat sink and fan
• SCR thermal protection with LED indication
• Optional over temperature alarm
• Optional load / line interrupt alarm
• USA & Canadian UL component recognition
• CE conformity
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:
- Minimum vertical distance between unit and
panel wall: 3.94” (100 mm)
- Minimum horizontal distance between unit and
panel wall: .79” (20 mm)
- Minimum vertical distance between adjacent
power control units: 11.81” (300 mm)
- Minimum horizontal distance between adjacent
power control units: .79” (20 mm)
During continuous operation, the heat sink can
reach very high temperatures, 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 cutting out
electrical power to the panel. Failure to do so
may cause serious injury or death.
