7 Installation and electrical connection

DANGER! Risk of fatal injury!
Incorrect installation and improper electrical
connections can be life-threatening.
• The installation and electrical connection may
only be carried out by qualified personnel in
accordance with the applicable regulations!
• Adhere to regulations for accident prevention!

7.1 Installation

NOTE:
Observe special requirements for country-specific
building codes, the conditions of permits and fire
safety reports.
• WM (wall mounted): For pressure boosting sys-
tems, the switchgear is mounted on the compact
system. If the wall device should be mounted
separately from the compact system, this is done
using 4 screws?, Ø 8 mm. While doing so, the pro-
tection type is to be ensured using suitable mea-
sures.
• Floor model, BM (base mounted): The floor model
is set up free-standing on a level surface (with
sufficient bearing capacity). In the standard, there
is a mounting pedestal 100 mm high for the cable
inlet. Other pedestals are available on request.
