Connect the power carrying wires to the orange two pole female plug labeled “L” and “N” which
came with the instrument. Attach these wires to each other with a cable tie tightly behind the orange
two pole female plug. Connect the protective conductor (PE) of the cable to the protective con-
ductor terminal . Plug the orange two pole female plug with the power carrying wires into the
orange two pole connector on the PCB. Give enough slack on the PE (Protective Ground ) to
ensure that, if the strain relief of the cable gland should fail, the power carrying wires are discon-
nected first.

The signal cable enters the cabinet through a water proof cable gland. The signal cable may be fed
through the Cabinet's hole together with the connector. It is held by a grounded cable clamp which
should have electrical contact to the cable shield. The different wires connect to the green PCB
connector, which is plugged into the green single row terminal block.
