Double circuit unit
■
Connecting the pump (3~50 Hz, 400 V) in case of OPSC or
OPTC
- For OPSC: pump contactor K1P is present
- For OPTC: pump contactors K1P and K2P are present
For each pump connection, use a cable containing 3 conductors
+ ground with a minimum conductor section of 2.5 mm
The length of the earthing cable may not exceed
10 m. If the distance between pump and switch box is
more than 10 m, the pump must be earthed
independant of the switch box.
Maximum running current/pump as in the table below.
