Electrical connection, control terminals and Display unit

Do the hydraulic assembling first before starting the electrical connection.
a) Open the 4 screws of the cover and remove the top cover.
b) Connect the motor cable and the supply cable.
c) If required, connect the control cable for the external release contact and the thermistor (PTC). If they are
not used; these inputs have to be bridged.
Cable gland type
M20x1,5
M16x1,5
M12x1,5
Do not connect the electronic ground with the other voltage potentials!
There is only single isolation of the control voltage. Between ground and GND of the control
voltage there can occur voltage levels >100VAC! Connected relays or switches therefore
have to have double isolated contacts.
