2.2.1.2 “/S400” Version Controllers
Controllers of the “/S400” version can be supplied with higher voltage – up to 500 V, either AC or DC.
The power demand is the same as those of standard version.
The supply voltage connects to terminals 3 (L1) and 5 (L2/N). In case of DC supply voltage the
polarity of connection is generally free, but for maximum electromagnetic compatibility grounded pole
should be connected to the terminal 5 (L2/N); see connection examples below.
Power supply voltage needs to be externally protected ( see following chapter).
Despite of standard version, power supply terminal 3 (L) is not internally connected to the common
pole of output relays. Terminals 4 and 6 are not used.

2.2.1.3 Novar 1005 / 1007 Controllers
The supply voltage connects to terminals 4 (L1) and 3 (N). Power supply voltage needs to be
externally protected ( see chapter Protection below ).
Power supply terminal 4 ( L1 ) is internally connected to the common pole of output relays. It is
necessary to dimension the power supply protection in consideration of output contactors’ power as
well.
