UK │ 5. Safety instructions and warnings
 Only connect unit to a permanently wired
electrical installation with NYM-O / NYM-J, 2
x 1.5 mm² or 3x 1.5 mm².
 The units may only be operated using the
voltage and frequency shown on the rating
plate.
 The degree of protection stated on the
rating plate is only guaranteed if installation is
undertaken correctly and if the connection
cable is correctly guided through the cable
grommet. The grommet must tightly seal the
cable sheathing.
 Unit may be energized even when at a
standstill and may be switched on

6. Installation preparations

Wall
NOTICE
If the surface is uneven, there is a dan-
ger of short circuits and damage to the
device if water can penetrate the
housing. Make sure there is a flat surface
in the area of the sealing ring. If necessary,
provide additional sealing measures.
The prescribed minimum distances
i
between the unit and the wall and
ceiling shown in figure D must be
observed.
1. Make sure the housing has a level base.
2. Fit wall breakthrough or drill core hole:
minimum diameter, 150 mm.
Recommendation: Fit wall sleeve
i
WH 150. Fit wall breakthrough with
minimum diameter 170 mm.

3. Lay power cable to installation location
(surface-mounted (AP) or recessed-moun-
ted (UP)); for clearances see  Fig. D.
Always note the relevant specifica-
i
tions for electrical installations and
when fitting equipment. In Germany
observe DIN VDE 0100 and the
corresponding parts in particular.
