Preparing the cable openings
The cables can be fed through openings on the
back of the housing or the underside of the
housing. The openings are pre-cut and must be
prepared as required before mounting.
You can prepare the cable openings on the
back of the housing as follows:
1. Break the cable openings 5 (Fig. 29)
through using a suitable tool.
2. Deburr the edges
You can prepare the cable openings on the
underside of the housing as follows:
1. Cut the required cable openings 8 (Fig. 29)
out left and right with a suitable knife and
break them through.
2. Deburr the edges.
Connect the electric cables
√ All cables are de-energised.
√ The cable openings are prepared.
Connect the cables whilst observing the following
points:
n Assign cables to the connection terminals as
described in the following section Ä ‘Terminal
assignment’ on page 29.
n Power input and outputs: First connect PE and
then N and L.
n Strain reliefs:
- First insert the strain reliefs at the bottom and
then the strain reliefs at the top.
- When using a strain relief at the top, use the
plastic bridge as described below.
- If the opening of a strain relief is too large,
e.g. for thin cables, turn the strain relief frame
(bend it downwards).
- Only use strain reliefs with cabling through
the underside of the housing. For cabling
through the back of the housing, use external
strain reliefs.
Insert or remove plastic bridges
You can insert the plastic bridges as follows:
1. Insert the right plastic bridge first using the
locking catch 1 (Fig. 30).
2. Press the other side of the plastic bridge
down 2 until the clip clicks into place.
3. Insert the left plastic bridge in the opposite
manner (locking catch left, clip right).
Fig. 30: Inserting the right plastic bridge
You can remove the plastic bridges as follows:
1. Insert a screwdriver 2 on the right plastic
bridge between the housing and the clip 1
(Fig. 31).
2. Carefully push the screwdriver to the left 3 .
In this way, raise the clip 1 to the right until
the plastic bridge 4 is free.
3. Pull the plastic bridge upwards using your
free hand 5 .
4. Remove the left plastic bridge in the same
way.
