Rittal Hygienic Design assembly instructions
HYGIENE RISK!
If the distance from the wall is too small, this prevents effec-
tive cleaning and so favours the accumulation of dangerous
micro-organisms. Choose the distance from wall sufficiently
large so that you can fully see the rear housing surface and reliably
reach it with the cleaning utensils. Use for the wall mounting only such
screws that the valid regulations and standards classify as being
hygiene uncritical.
DANGER!
If the HD wall spacer brackets are mounted on the wall
without the HD compact enclosure, there is the danger
of severe injury being caused by colliding with the ends
protruding into the room. Barricade the area during mounting so
that no unauthorised persons can enter this area.

HYGIENE RISK!
To prevent the accumulation of dangerous micro-organ-
isms, the following items must be considered for welding
the HD compact enclosure:
● Hollows, dead spaces and gaps that cannot be seen and cleaned
must be prevented or sealed hygiene-conform.
● The welding seams must be continuous and hygiene-conform, and,
if necessary, reworked.
NOTE!
Never weld directly on the HD compact enclosure.
A guarantee for the standards and specifications named
by Rittal is then void because this can cause distortion
to the HD compact enclosure. Consequently, indirect welding
should be used in preference, for example, using spacer brackets.
Information for welding
● Recommended welding procedure: TIG (without spatter formation),
with or without additive
● Additive: Higher alloyed than the base material of the HD compact
enclosure (corrosion protection)
● Process: With the least possible generation of heat to prevent distor-
tion and joint changes. Tarnishing colours (rough, brittle surfaces)
must be prevented by using an appropriate inert gas or removed
with reworking.
