All protection functions including dc/dc converter are accommodated on a printed cir-
cuit board of double Europe format. This p.c.b. forms, complemented by a guide plate,
a multi-pin terminal module (p.c.b. side) and a front unit, the plug-in module which is
mounted in a 7XP20 housing. The inner part of the housing is free from enamel and
thus functions as a large contact plane and shield with solid electrical conductivity and
mates with the earthing plates of the module. Connection to earth is made before the
plugs make contact. An earthing area marked with an earth symbol has been provided
at the housing rear. At this area an earthing strip must be connected with two earthing
screws in order to ensure solid low-impedance earthing.
