8.3.2 Mounting the universal DIN rail adapter

Tomounttheuniversal DIN rail adapter on theleftside ofthe

device, proceed as follows:

1. Position the universal DIN rail adapter on the left side of

the housing so that the mounting holes are congruent

with the hole pattern for the mounting holes.

2. InserttheTorxscrewsthatwereremovedearlierinto the

appropriate hole pattern on the universal DIN rail

adapter so that the necessary drill holes on the power

supply can be accessed.

3. Screw the universal DIN rail adapter onto the power

supply.

Retrofitting the universal wall adapter

The UWA 182/52 universal wall adapter (Order No.

2938235) or UWA 130 universal wall adapter (Order No.

2901664) is used to attach the power supply directly to the

mounting surface.

The use of universal wall adapters is recommended under

extreme ambient conditions, e.g., strong vibrations. Thanks

to the tightscrew connection between the power supply and

the universal wall adapter or theactual mounting surface,an

extremely high level of mechanical stability is ensured.

8.4.1 Mounting the UWA 182/52 universal wall

adapter

Proceed as follows to disassemble the universal DIN rail

adapter that comes pre-mounted:

1. Remove the screws for the universal DIN rail adapter

using a suitable screwdriver (Torx 10).

2. Separate the universal DIN rail adapter from the rear of

the power supply.

3. Position the universal wall adapter in such a way that

the keyholes or oval tapers face up. The mounting

surface for the power supply is the raised section of the

universal wall adapter.

4. Place the power supply on the universal wall adapter in

the normal mounting position (input voltage connection

terminal blocks below).

5. Insert the Torx screws into the appropriate hole pattern

on the universal wall adapter so that the necessary

mounting holes on the power supply can be accessed.

6. Screw the universal wall adapter onto the power supply.

adapter

The maximum tightening torque of the Torx screw

(Torx® T10) is 0.7 Nm.

The power supply is attached to the UWA 182 or

UWA 130 universal wall adapter by means of the

Torx screws of the universal DIN rail adapter.

The maximum tightening torque of the Torx screw

(Torx® T10) is 0.7 Nm.

Make sure you use suitable mounting material

when attaching to the mounting surface.
