All connection terminals are plug-in terminals. The terminals are separated to
prevent faulty wiring for terminals connected to AC 230 V (supply, relay outputs).
Cable strain relief for lines for terminals 19 ... 28
(AC230 V) is mandatory. Attach the lines to the
related lugs on the housing base using cable
blinders (see picture, right).
Plug-in terminals connected to power must be
removed from power prior to plug-in or plug-out!
