Installation
The plug of the power supply cord is used as a separator. This separator must be clearly recognisable
and easily accessible by the user. A plug connector with a CEE7/7 system is necessary.
All the electrical lines carrying supply voltage or another voltage that is dangerous in the case of con-
tact (power supply cord, alarm and indicator relays), must additionally be equipped with double or rein-
forced insulation (EN 61010-1). This can be ensured by using plastic-sheathed cables, a second insu-
lation (e.g. flexible insulating tubing), or correspondingly suitable lines with reinforced insulation.
The connecting cables can be equipped, for example, with flexible insulating tubing.
The additional flexible insulating tubing must withstand the electrical and mechanical stresses which
can occur during the intended use (see EN 61010-1, Clause 6.7.2.2.1).
DANGER!
Supply voltage!
When wiring the connecting lead, it must be ensured that the double or reinforced insulation be-
tween the electric circuits that are dangerous in the case of contact and the contactable secondary
circuit remains maintained.
NOTE!
The additional insulation must be suitable for a test voltage of 1500 V alternating current.
The thickness of the insulation must be at least 0.4 mm.
E.g. flexible insulating tubing, type BIS 85 (Bierther GmbH).
The additional insulation of the connecting leads (mains connection, alarm and indicator relays) can
be implemented as follows:
(1) - Terminals (connectors)
(2) – Flexible insulating tubing for the connecting leads
(3) – Connecting cable
