Device Installation
1. The unit is designed for mounting inside housings (control panel, switchboard) insuring appropriate protection
against surges and interference. Metal housings must be connected to ground in a way that complies with the
governing regulations.
2. Disconnect the power supply prior to starting assembly.
3. Check the connections are wired correctly prior to switching the unit on.
In order to install the unit, a 90.5 x 43 mm mounting hole (Figure A, B) must be prepared. The thickness of the ma-
terial of which the panel is made must not exceed 5mm. When preparing the mounting hole take the grooves for
catches located on both sides of the housing into consideration (Figure A, B). Place the unit in the mounting hole
inserting it from the front side of the panel, and then fix it using the brackets (Figure C). The minimum distances
between the centre points of multiple units - due to the thermal and mechanical conditions of operation - are
115 mm x 67mm (Figure D).

Due to possible significant interference in industrial installations,
appropriate measures assuring correct operation of the unit must
be applied.
The unit is not equipped with an internal fuse or power supply circuit breaker.
For this reason, an external time-delay cut-out fuse with a small nominal
current value must be used (recommended bipolar, max. 2A) and a power
supply circuitbreaker located near the unit.
In the case of using a monopolar fuse it must be mounted on the phase cable.
