Installation / assembly
5.1
Surrounding conditions
•
Dry and frost-proof
•
Adequate ventilation
•
The control system installation must be flood-proof
•
The technical data, especially the maximum permissible ambient temperature, must
be observed.
•
The control system must not be exposed to direct sunlight.
5.2
Control system assembly notes
The device is intended for wall mounting. Assembly may take place via the existing holes in
the housing or via the associated wall straps, if present. The installer is responsible for
selecting the appropriate material for attachment. Make all the necessary electrical
connections after assembly.
Attention!
You must be careful to not let any moisture into the control system during any kind of work on
the system. Ingress of moisture must be prevented during assembly and/or as long as the
electrical connections of the control system are exposed through an open door, even with only
light precipitation, e.g. by covering it with a tarpaulin. After completed installation and also in
case of longer breaks, close the cover.
The enclosure door must be firmly closed to be in compliance with the
respective protection rating! Unused fittings must be closed off with a
blind plug!
Should the electrical connection not be completed immediately after the mechanical
installation, possible ingress of moisture via open cable fittings must be prevented with
temporary bungs.
5.3
Immersion probe assembly notes
The function of the immersion probe is mostly independent of the installation position.
The protective cap may only be removed immediately before installation
in order to protect the process connection and the pressure diaphragm.
To prevent measurement errors and damage, the immersion probe should
be installed in a flow- and turbulence-free location, or in a guide tube!
