If the pump is operated without the HMI, the supplied sealing cap must be
plugged into the CAN port above the LEDs of the pump base.
CAUTION!
Risk of short circuit
If liquid penetrates into the CAN port, a short circuit may
occur in the pump.
– A CAN plug or the supplied sealing cap must always be
plugged into the CAN port.
CAUTION!
Danger of malfunctions
Incorrect operation via the CAN bus leads to malfunctions.
– When operating with the HMI connected, do not connect
any other control (e.g. DXCa) to the CAN port.
7.2.3
Pump, power supply
WARNING!
Risk of electric shock
This pump is supplied with a grounding conductor and a
grounding-type attachment plug.
– To reduce the risk of electric shock, ensure that it is con‐
nected only to a proper grounding-type receptacle.
WARNING!
Danger of electric shock
In the event of an electrical accident, it must be possible to
quickly disconnect the pump, and any electrical ancillaries
which may possibly be present, from the mains.
– Install an emergency cut-off switch in the mains supply
line to the pump and any electrical ancillaries which may
be present or
– Integrate the pump and electrical ancillaries which may
be present in the emergency cut-off management of the
system and inform personnel of the isolating option.
WARNING!
An on/off switch may not be fitted on the pump, dependent
on the identity code and installation.
To be able to switch off the pump (to a zero-volts state) inde‐
pendently from the entire installation (e.g. for repair), use an
electrical isolating device in the mains supply cable, e.g. a
mains switch or a plug / socket combination. Clearly identify
this isolating device as such.
Install the pump cable.
