Load circuit
230V AC model: The connection with mains power supply should be done by only trained and authorised persons. The electrical connection is done through
the 9-pin plug connector as per pin configuration. The device can be operated only with 230V AC supply. The mains supply connection is protected against
over-voltage through a 390V varistor. The safety of the device against too high load current should be ensured through an external protection arrangement.
The terminal PE is not connected to the device and is only used to fix or clamp the PE wire. Its wiring is not necessary.
The container with the medium should be grounded by suitable means to protect against high voltages in case of malfunction.
The safety of load circuit, if required, should be taken care of through some external protection arrangement. (max. 5A NO contact, 2A NC contact). To
switch higher currents, corresponding switching elements should be used.
The NO/NC contacts of both the relays are potential free and are terminated at the connection socket. The connection of load is done as per connector
configuration. The NO contact of the relay is provided with a 390V varistor for surge suppression.
