Caution
Open the isolating valve on the discharge manifold. 2.
Close the isolating valve on the discharge manifold.
3. Turn the main switch to “I”
position.
4. Open the ball valve for testing the pressure switches for the
main pump and the jockey pump.
10.2 Electrical connection
Warning
During electrical installation, make sure that the
power supply cannot be accidentally switched on.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
The electrical connection must be made in accordance with the
wiring diagram in the control cabinet.
Procedure
• The connection to the mains supply must be fitted with a fuse of
the correct size, in accordance with local regulations, and con-
nected to the main switch in the control cabinet. PE must be
connected using the PE terminal block.
• Pressure switch 1 for the main pump must be connected to termi-
nals 6 and 7 in the control cabinet, and pressure switch 2 for the
main pump to terminals 8 and 9.
• The pressure switch for the jockey pump must be connected to
terminals 2 and 52 in the control cabinet.
• The pressure switch for dry running protection of the jockey pump
must be connected to terminals 53 and 54 in the control cabinet.
If this pressure switch should not be used, put a cable/bridge
between terminal 53 and 54
• The additional pressure switch for the “Pump running” indication is
to be connected to terminals 12 and 13. If no additional pressure
switch is used, put a cable/bridge between terminal 12 and 13.
• If there is a level switch for measuring the filling level in the
priming tank, it must be connected to terminals 10 and 11.
• If status and alarm indications are to be transmitted to a building
management system, terminals 31 to 40 must be used for this
purpose.

11. Commissioning
Warning
Start-up must be carried out by authorised
personnel. The control cabinet of the controller
must remain closed during start-up. Danger of
death through electric shock!.
The sprinkler pump is not allowed to run against a
closed valve as this may cause an unacceptable
temperature increase or the formation of steam.
This may cause damage to the sprinkler pump.
11.1 Preparations before start-up
Before start-up the following have to be done:
1. Check that all screw connections are fitted securely.
2. Check that all pipes are installed correctly.
3. Check that all electrical connections inside and outside the
controller are correctly connected and fitted securely. 4. Check
that all fuses in the control cabinet are switched on.
5. Check that all safety devices are installed.
6. Make sure that any storage tank and pump priming tank are
filled with enough water.
7. Set pressure values on the three pressure switches, see pres-
sure switch operating manual. The value of the pressure
switches for the main pump should be 0.5 bar higher than the
value of the pressure switch for the jockey pump.
11.2 Start-up
Before switching on the extinguishing water
booster set it must be filled with water. In case
of dry running the main pump will not stop.
Step
Illustration
1. Open the isolating valve on the suction manifold. Open the
isolating valve on the suction side of the main pump.
Open both isolating valves of the bypass line.
