● In addition to connecting the supply voltage (L+/M) to X6, the supply voltage (UP/ZP) must
be connected to all connectors.
● ZP must be connected to all connectors (X1, X2, X3, X7, X8, X9).
● UP must be connected to all connectors (X7, X8, X9).
● L+/M and UP/ZP must always be supplied with voltage.

Ensure that no earth loops are
created and that FE and
Faston are connected to the
same earthing potential.
