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).
i
The safety-related application (SIL 3 in accordance with IEC 61508) of the outputs and the
actuators connected must comply with the safety requirements. For more information, refer
to the HIMax Safety Manual.
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).
Operation is only permitted with the suitable connector board, 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, twisted pair cable may be used for connecting field current circuit to
the digital outputs.
- On the module side, the shielding must be connected to the cable shield rail (use
SK 20 shield connection terminal block or similar).
- 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.
The outputs can be interconnected redundantly using the corresponding connector boards,
see Chapters
3.6 and 4.5.
4.1.1 Wiring Outputs not in Use
Outputs that are not being used may stay open and need not be terminated. To prevent
short-circuits and sparks in the field zone, never connect a wire to a connector board if it is
open on the field side.
