CONTROL WIRING TERMINALS

CONNECTIONS FOR REMOTE START/STOP

* Emergency Stop

A Safety or Emergency Stop function can be implemented
by removing the J1 jumper connecting terminals ES1
and ES2. The emergency stop device will then be wired
between ES1 and ES2. When an emergency situation
(high pressure, high temperature, …) is encountered the
device must open to disconnect control power to the
circuitry enabling the soft starter. This will then stop the
pump/motor. This control device must be sized to operate
at 2.5A at 115Vac.

CAUTION! THE EMERGENCY STOP DEVICE DOES
NOT DISCONNECT LINE POWER TO THE SOFT
STARTER.
