Electrical connection
Caution:
It is obligatory that an electrician has to make the connection. Incorrect connection is
dangerous to life.
In the connection box of the motor, there are 2 short cables (brown and blue). These
cables are left from the test run and show the right connection. Remove them before
connecting the new cables.
Connection cables, fuses and possibly necessary on-board main power switch of the
distribution on board to the system are not included in the scope of delivery and have
to be supplied on-board.
Required cable cross-sections up to 15 meter cable length, longer wires have to be
enlarged:
From board’s main distribution to the junction box:
230 Volt 50 Hz: 3 G 2.5 mm² (AWG 13) / 115 Volt 60 Hz: 3 G 10 mm² (AWG 7)
400 Volt 50 Hz: 3 G 1.5 mm² (AWG 15)
From the junction box to the motor high pressure pump:
230 Volt 50 Hz: 3 G 2.5 mm² (AWG 13) / 115 Volt 60 Hz: 3 G 10 mm² (AWG 7)
400 Volt 50 Hz: 3 G 1.5 mm² (AWG 15), direction of rotation arbitrary.
Supply line from the junction box to the feed pump: 3 G x 1 mm² (AWG 17)
