Building Technologies 2016-12-23
A plug-in terminal is provided for the commissioning and service tool.
All other terminals are fixed.
To avoid incorrect wiring, terminals which can be connected to AC 230 V (supply and
relay outputs) are physically segregated from the other terminals. They are arranged so
that, under normal circumstances, all incoming and outgoing cables can be connected
without crossing.
STOP
Caution
Cable restraints must be used for the wires to terminal
blocks X4 and X5 (AC 230 V).
The conductors must be secured with cable ties (see
diagram, right).
