Power Supply
The following table lists the most important tests and limits for the HIMatrix systems' power
supply:
IEC/EN 61131-2
Verification of the DC supply characteristics
The power supply must comply with the following standards:
IEC/EN 61131-2:
SELV (Safety Extra Low Voltage) or
PELV (Protective Extra Low Voltage)
HIMatrix systems must be fuse protected as specified in this manual
Voltage range test:
24 VDC, -20...+25 % (19.2...30.0 V)
Momentary external current interruption immunity test:
DC, PS 2: 10 ms
Reversal of DC power supply polarity test:
Refer to corresponding chapter of the system manual or data sheet of
power supply.

2.2.2
Noxious Gases
HIMatrix components may be operated without functional and safety restrictions in
environments with noxious gas concentrations as described in the following standards:
ANSI/ISA -S71.04:1985
Corrosive gases, Class G3
DIN EN 60068-2-60: 1996 (also IEC 68-2-60: 1995)
With noxious gas concentrations higher than those mentioned in the standards, a reduced
component lifetime is to be expected. The user is responsible for demonstrating that the
environment is sufficiently free from noxious gases.
2.3
Tasks and Responsibilities of Operators and Machine and System
Manufacturers
Operators and machine and system manufacturers are responsible for ensuring that HIMatrix
systems are safely operated in automated systems and plants.
Machine and system manufacturers must sufficiently validate that the HIMatrix systems were
properly programmed.
2.3.1
Connection of Communication Partners
Only devices with safe electrical separation may be connected to the communications
interfaces.
2.3.2
Use of Safety-Related Communication
When implementing safety-related communications between various devices, ensure that the
overall response time does not exceed the fault tolerance time. All calculations must be
performed in accordance with the rules given in this chapter.
