4 Start-up
This chapter describes how to install, configure and connect the HART module to the analog
input and output modules. For more information, refer to the HIMax manuals for the analog input
and output modules and the HIMax Safety Manual (HI 801 003 E).
i
The safety
-related application (SIL 3 in accordance with IEC 61508) of the inputs and the
proximity switches connected m
ust 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 suitable connector board. For more information, see
Chapter 4.8.
 Only operate the module in parallel with the appropriate analog input or output module.
 The modules and their 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.
- Use shielded cables with twisted pairs.
- Connect one twisted pair of the shielded cable to each of the channels.
- 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.
 If the supply is used, utilize the voltage output used for the assigned channel, see 5.4.1.
 HIMA recommends using the supply of the analog input module.
If an external supply or measurement unit fails, the affected channel 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 analog modules may be wired redundantly using the corresponding connector boards.
For more information, see Chapters 4.8 and 5.4.
4.1.1 Wiring I/O Channels Not in Use
I/O channels 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.
