The tank must be connected mechanically and electrically to the pressure booster
system prior to commissioning of the system.
6.6 Fitting the dry running protection device
Install the dry running protection device supplied together with the pressure booster
system as a separate, non-fitted accessory, or supplied at a later date for retrofitting,
in accordance with its operating instructions and connect it to the switchgear and
controlgear assembly.
The switchgear and controlgear assembly is provided with the requisite inputs.
For a multiple pump system:
1. For information on connecting the external dry running protection device, refer
to the circuit diagram.
For a single-pump system:
1. Remove the front cover to access the terminal strip.
NOTE
The new frequency inverter generation is equipped with a second relay.

In the case of direct connection (direct connection of the pump system to the
drinking water supply line of the public water supply system):
1. Use a wire jumper to connect DI1 (B4) and +24 V (B3).
ð When this connection type is used, monitoring by the suction-side pressure
sensor protects the pump system against lack of water.
In the case of indirect connection (connection to an unpressurised drinking water
reservoir (water tank)):
1. Remove the wire jumper between DI1 (B4) and +24 V (B3). Connect an external
dry running protection device (e.g. a float switch) in its place.
ð
When this connection type is used, the lack-of-water function must be
adjusted.
