4.2.2 Mains connection
The control box can be connected to a single or three-phase power supply according to the motor which is used (see Wiring
diagrams page 75). It is essential to refer to the wiring diagrams as a bridge may be required (visible on the diagram).
Use the right cable gland (when looking at the open box) for the cable entry of the mains cable.
NOTICE
Ö The power supply has to be secured by an independent all-pole circuit breaker which can be switched off
(max. 20 A).
4.2.3 Connection of the pump motor
It is possible to connect either a single-phase or a three-phase motor, 50 HZ or 60 Hz: see Wiring diagrams page 75.
Use the left cable gland (when looking at the open box) for the cable entry of the pump cable.
4.2.4 Thermocontactors wiring
The Control Box ZPS1.3 is equipped with 2 control circuits to connect the thermocontactors of the pump (see 4.2.1 Locations
overview):
- TH1 control circuit: If the pump is connected to the TH1 control circuit, in case of overheating, the motor will stop and an error will
be signalled. When the motor has cooled down sufficiently, the pump will start again automatically.
- TH2 control circuit: If the pump is connected to the TH2 control circuit, in case of overheating the motor will stop. For the pump
to restart, the motor must have cooled down and the malfunction must be reset by pressing the key.
IMPORTANT
When connecting a single pump, the connection to the TH1 control circuit is recommended.
The control box must be installed indoors, in a place protected from humidity and frost.
Mount the box on a flat surface, using the diagram on the left.
Remove the front of the box to identify the slots.
