- The incoming power cable must be of sufficiently
large sized to maintain protection from moisture
ingress and to ensure a tight gland grip (e.g. H05W-
F3G1,5 or AVMH-3x1,5).
- Heat resisting cable must be used when installing the
pump in systems with water temperatures above 90°C.
- Cable leads to be routed such to avoid any contact
with the adjoining pipework and/or the pump or
motor housings.
SIRIUX JR BMS : Make signal connections according to
Fig. 5 :
NOTE : The pump must be switched off !
- If no BMS functions are to be used, the PG screwed
connections must be closed with the dummy plugs
supplied.
- The integrated, potential-free collective fault signal
(SSM) of the SIRIUX JR BMS is available at the
connection (Fig. 5, item 1) as an NC contact. SSM
opens approx. 120 seconds after a fault occurs or
after all the re-start attempts have lapsed and closes
after the fault has been remedied or after switching
off the mains.
Contact load :
• minimum permitted: 12 V CC, 10 mA
• maximum permitted: 250 V CA, 1 A
SSM : Make the connection according to Fig. 5 and as
described below Fig. 5 :
- Take the cable through the PG screwed connection
(PG 9 with sole use of the SSM function specified for
cables between 5–8 mm and a cable cross section
of 0,5 and 1,5 mm2),
- Connect cable according to item 1.
- The LED lights up green in normal operation. The LED
lights up red if the following faults occur:
• Blockage
• Motor defect
• Internal short-circuit
External OFF : Make connection according to Fig. 5 as
described below:
- Remove bridge!
- Take the cable through the PG screwed connection
(PG 9 with sole use of the External OFF function
specified for cables between 5–8 mm and a cable
cross-section of 0,5 and 1 mm2),
- Connect cable according to Fig. 5.
0–10V : Make the connection according to Fig. 5 and
as described below Fig. 5 :
- Take the cable through the PG screwed connection
(PG 11 for cables between 6–10 mm and a cable
cross-section of 0,5 and 1,5 mm2),
- Connect cable according to Fig. 5,
- Control diagrams according to Fig. 6.

NOTE : Disconnect the pump from the mains
before operating the DIP switch.
Important switch positions :
- Selecting the DIP switch 2 at position 'n' means that
the pump is not controlling any more, because it is
now running in the remote speed control mod (fixed
speed).
- Selecting the DIP switch 1 in position '0–10V' means
that the pump can no longer be operated locally at
the red button.
8. COMMINSSIONING
WARNING ! Risk of burns! !
Depending on the pump or system operating
conditions (fluid temperature), the entire pump can
become very hot.
Touching the pump can cause burns!
8.1 Filling and ventilation
Fill and bleed the system correctly. The pump rotor
chamber normally bleeds automatically after a short
time in operation.
However, if the rotor chamber has to be bled directly,
proceed as follows:
- Switch off the pump,
- Close the shut-off device on the pressure side.
WARNING ! Risk of burns! !
Depending on the system pressure and
temperature of the fluid, when the bleeder screw is
opened, hot liquid or gaseous fluid may escape or
shoot out at high pressure. There is a risk of scalding!
- Push through the perforation in the centre of the
name plate and carefully open the bleeder screw,
- Protect electrical parts from any water that escapes,
- Carefully push back the pump shaft with a
screwdriver several times.
