General information on installation/dismounting

DANGER!
With multichannel controller module 705010 and relay module 705015, the load circuits from re-
lay 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 removed 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.
Explosion hazard.
 The entire system must only be used outside of areas with an explosion hazard.
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.
Type 705070 panels are designed for installation in a panel cut-out. Information on the protection type
and other technical data can be found in data sheet 705070.
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 rea-
sons of stability, the spacing of the fastening screws for the DIN rail should not exceed 200 mm. The min-
imum distances for the modules that are specified in the module-specific installation or operating
instructions must be observed.
Installation position
The DIN rail should be mounted horizontally so that all modules are arranged vertically. Otherwise 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 distances the minimum
bending radius of the cables, the performance of the electrical installation, and the clear arrangement of
the plant are no longer guaranteed.
Cleaning
Only use a dry cloth for cleaning the modules (protection type IP20).
