Installation Instructions

Introduction

The CS-625 current switch is a solid-state switch that monitors

line current for electrical loads such as pumps, conveyors,

machine tools or fans and closes the output contacts when

the adjustable trip point is exceeded. It is typically used to

monitor motor operation and can be used to determine

on/o status, proof of operation, motor failure or belt loss.

The sensor requires no external power as it is totally powered

by induction from the primary AC line being monitored. The

trip setpoint is adjustable in three jumper-selectable ranges

from a minimum value (1 Amp) up to 175 Amps by rotating

the adjustment pot counter-clockwise.

The output contacts can switch loads up to 1 Amp 240 Vac.

**** WARNING ****

- Electric Shock Hazard, Use Caution

- Disconnect and lock out power before installation

- Follow national and local electrical codes

- Read and understand these instructions before installing

- Installation only by qualied electrical personnel

- Do not rely on this device to indicate line power

- Only install this device on insulated conductors

- Only install on 600 Vac maximum conductors

- Do not use this device for life-safety applications

- Do not install in hazardous or classied locations

- Install this product in a suitable electrical enclosure

- Failure to follow these instructions may result in

serious injury or death.

Installation

-Read all warnings before beginning

-Ensure the selected device has the correct ratings for

application

-Set the range jumper to the desired range. (See Figure 1)

-Mount the sensor with two screws through the base .

The base has an integral mounting tab to allow screw

mount to a surface.

If predrilling is required, the actual device may be used to mark holes. The

mounting holes in the base will accommodate up to a #10 size screw (Not

supplied) . See Figure 2

Place the monitored conductor through the sensor hole and reconnect. See

Figure 3.

-The CS-625 is not polarity sensitive. Use shielded wiring for all connections and

do not locate the device wires in the same conduit with wiring used to supply

inductive loads such as motors. Make all connections in accordance with national

and local codes.

-Reconnect the power
