2.1 General information on installation/dismounting
Mounting site
All modules have protection type IP20 and are only intended for use in fireproof control cabinets
or switch boxes. The mounting site should be virtually vibration-free. Electromagnetic fields
caused by equipment such as motors or transformers should be avoided.
Multifunction panel 840 has protection type IP67 at the front and is intended for installation in
a panel cut-out. The rear has protection type IP20.
Climatic conditions
The ambient temperature and the relative humidity at the mounting site must correspond to the
technical data. Aggressive gases and vapors have a negative effect on the operating life of the
modules. The mounting site must be free from dust, powder, and other suspended matter so
that the cooling slots do not become blocked.
DIN rail
All modules are mounted on a DIN rail according to DIN EN 60715 (35 mm × 7.5 mm × 1 mm).
For reasons of stability, the spacing of the fastening screws for the DIN rail should not exceed
200 mm. The minimum distances for the modules that are specified in the module-specific in-
stallation or operating instructions must be observed.
Installation position
The DIN rail should be mounted horizontally so that all modules are arranged vertically. Other-
wise the admissible ambient temperature range will be restricted.
Space requirement
The modules require the minimum distances shown in the following figure for the purpose of
installation/dismounting and for future maintenance or replacement. In the event of shorter dis-
tances the minimum bending radius of the cables, the performance of the electrical installation,
and the clear arrangement of the plant are no longer guaranteed.
DANGER!
With multichannel controller module 705010 and relay module 705015, the load circuits from
relay or solid state relay outputs can be operated with a dangerous electrical voltage (e.g.
230 V).
There is a risk of electric shock.
Prior to the installation/dismounting of these modules or the removal of the module insert, the
load circuits are to be disconnected from the voltage and the terminal strips are to be re-
moved from the module. This work must only be performed by qualified personnel.
WARNING!
The modules must never be installed in areas with an explosion hazard.
There is the risk of an explosion.
The entire system must only be used outside of areas with an explosion hazard.
