4 Start-up
This chapter describes how to install, configure and connect the module. For more
information, refer to the Safety Manual (HI 801 003 E).
4.1 Mounting
Observe the following points when mounting the module:
Only operate the module with the appropriate fan components. For more information,
see the System Manual (HI 801 001 E).
Only operate the module with the suitable connector board. For more information, see
Chapter
3.6.
The module and its connected components must be mounted to provide protection of at
least IP20 in accordance with EN 60529: 1991 + A1: 2000.
NOTE
Damage due to incorrect wiring!
Failure to comply with these instructions can damage the electronic components.
Observe the following points:
Plugs and terminals connected to the field zone.
- Take the appropriate earthing measures when connecting the plugs and terminals to
the field zone.
- An unshielded cable may be used for connecting proximity switches and switching
contacts to the digital inputs.
- When using stranded wires, HIMA recommends fastening ferrules to the wire ends.
The terminals must be suitable for fastening the cross-sections of the cables in use.
If the supply is used, utilize the supply output used for the assigned input, see
Table 9.
HIMA recommends using the supply of the module.
If an external supply or measurement unit fails, the affected digital input on the module
can be overloaded and damaged. If an external supply is required for the given
application, check the switching threshold following a non-transient overload that
exceeds the limit values of the module.
The inputs can be interconnected redundantly using the corresponding connector
boards, see Chapters
3.6 and 4.4.
4.1.1 Wiring Inputs Not in Use
Inputs that are not being used may stay open and need not be terminated. To prevent
short-circuits, never connect a wire to a connector board if it is open on the field side.
