21 - Connection Considerations

•  All cables connected must be heat-resistant to at least +185 °F.

•  All cables connected must be installed in accordance with The National 

Electric Code NFPA 79 / EN 60204-1.

•  All wires to the communications module must be connected to the termi-

nals or cut. No loose wiring permitted.

Warning: 

Voltages over 24V AC/DC are possible on NO, 

C, NC Terminals.

Cable outer layer must not be stripped longer than 0.59 

inches. 

Warning: 

Before performing any work on the module, make 

sure that the pump and module electricity supply has been 

switched off and that it cannot be accidently switched on.
