10 Mounting on DIN rails

Assembly

To mount on an EN DIN rail, snap the device straight onto the

DIN rail.

If the power supply unit is to be fastened directly onto an even

surface, press the orange base latch upward and down.

Place a washer between the pulled-out base latch and the

even surface (max. outer diameter 8.5 mm, max. thickness

1.3 mm, e.g., spring washer for M4 in acc. with DIN 127-B or

toothed lock washer in acc. with DIN 6797).

Then fasten the device with two screws (max. thread

diameter 4 mm, max. head diameter 8.5 mm).

Removing

To dismantle from the EN DIN rail, press the orange base

latch outward and pull the device off of the DIN rail.

In the case of wall mounting, loosen the screws and press the

base latch inwards again.

11 Connection to various systems

TN-S TN-C

TT iT

PEN

The 100 V AC ... 240 V AC connection is made using the L and N screw connections.

The device can be connected to 1-phase AC networks or to two of the phase conductors of three-phase systems (TN, TT or

IT networks in acc. with VDE 0100-300/IEC 60364-3) with nominal voltages of 100 V AC ...240 V AC.

For operation on two of the phase conductors of a three-phase system, an isolating facility for all poles must

be provided.
