Electrical connection
The electrical installation is only allowed to be
performed with the electrical power supply
switched off.
Safety switches may not be bypassed (contacts
jumpered), turned away, removed or rendered in-
operative in any other manner.
All electrical connections must be isolated from
the mains either by an isolating transformer
(EN 61558-2-6) or using a comparable isolation
method.
All output contacts in the case of capacitive and
inductive loads must feature an adequate sup-
pressor circuit.
Provide external contact fusing (see chapter 7.2.3
"Technical data T4000-1RB.01") for relay outputs.
To ensure that safety is maintained, both output
signal switching devices (relay outputs) 13/14
and 23/24 must be evaluated.
