Before starting operation in hazardous locations
1
Connect the earth continuity conductor (earth wire) to the designated screw on the
explosion-proof motor.
2
Connect the earth continuity conductor (earth wire) to the designated screw on the pump.
3
The containers should be grounded separately, if they are not already grounded by the mode
of the installation.
4
Only use electrically conductive hoses. This will provide a conductive path for the pump,
hose and fittings.
5
Only use an explosion-proof plug device or an explosion- proof terminal box for connecting
the pump to the mains.

If the electrical socket or terminal box is positively located outside the hazardous area,
connection to explosion-proof equipment must not be undertaken.
Only use explosion-proof electric motors which are approved for ZONE 1.
The explosion-proof motor has to be outside the container.
For transferring flammable liquids only use pumps which are approved for such
application.
Only clean the power supply cable outside of the hazardous area.
For use in hazardous locations
Put the motor onto the pump.
Always check the power supply cable for damage before starting operation.
Keep solvents away from the power supply cable.
Before inserting the electrical plug into the socket ensure that the Start/Stop switch is
set to "0" ( Stop ).
Insert the plug.
Switch on the motor.
