circuits may belong to the same multi-conductor
cable if the insulation of the highest voltage occur-
ring in the cable suffices.
Para. 4.4.2 accordingly: In the case of possible func-
x
tional interference due to EMC, signal lines with a
low power cable level should be separated.

6. Operation
6.1
Filling and venting the unit
The system must be filled and ventilated properly. The
pump rotary box is ventilated automatically after ope-
rating for a brief time. Brief dry running will not damage
the pump.
Depending on the operating condition of
the pump and/or installation (fluid tempe-
rature) the entire pump can become very
hot.
Avoid touching the pump owing to the
risk of burning. The temperature at the
heat sink can be up to 70 °C within the
permissible operating conditions.

6.2
Setting the pump power
The unit is set to a specific operating point (point of
maximum load, calculated maximum heating require-
ments). When starting up for the first time, the pump
capacity (delivery head) is to be set in accordance with
the system operating point. The factory presetting
does not correspond to the pumping capacity required
for the system. It is calculated on the basis of the cha-
racteristics diagram of the selected pump (from the ca-
talogue/data sheet). See also Figs 8 to 10.
