Terminal assignment
3 Connection
This section describes the terminal assignments followed by some
typical connections. Sections 3.1 to 3.5 contain speciic instructions
and the speciications for the individual terminals. The inputs and out-
puts are assigned to plug-in screw terminals. These are coded to pre-
vent reversed polarity.

Option relay contact
Litz contact only by means of connector sleeves with insulating
enclosures for reasons of shock protection according to EN 61010.
Do not otherwise assign contacts that have been left unassigned ex
factory. We recommend to screen all sensor terminal leads and to
ground the shield on one side. Shields on both sides are recommen-
ded in case of RF interference or in case of equipotential bonding
over long distances. The sensor leads should not be in the same
phase winding as the mains supply and the output contact leads.
