5. Connect the power cords 1 and 2 accordingly to mains connection 1 and 2 (
9
,
10
or
11
,
12
), according to the following installation example (see below) and the connection
diagram following it and take care to leave the ground connector longer than the other
cords in every case. Also see that the cables do not come in contact with the pump (
4
)
or other hot objects such as the water pipelines at any point, so that the insulation is not
damaged.
6. Connect the other end of the power cord to the power grid via the separator which is
absolutely required in all cases.
7. Secure the individual mains connections according to the cable cross section and the
maximum power consumption. Note that the separation distance between the poles must
be a minimum of 3.0 mm.

Connecting power cord to the compact device
The following method is applicable as appropriate for all compact devices, but will be explained
here on the basis of the example of a B8 model compact device (H-Generation) and B9 model
(G-Generation) (
→
Installation example: Compact devices, p. 179
).
Carry out the following steps to connect the power cord to the compact device:
1. Open the compact device (
→
6.5 Opening devices, p. 148
).
2. If a cover is available on the rear side of the cabinet on the cable gland (depends on mod-
el), remove the cover before connecting the cable and re-assemble it afterwards.
If a cable sleeve is available (depends on model), cut the cable sleeve in the form of a
cross using a knife.
3. Guide the cable through the cable glands (
2
,
3
) into the device.
4. Fix the cables using cable binders (
5
) and cable holders (cable reliefs) (
8
).
