2.3.3 EMC Requirements
Higher interference levels are required for safety-related systems. HIMatrix systems meet
these requirements in accordance with IEC 62061 and IEC 61326-3-1 (DIS). See column
"Criterion FS“ (Functional Safety).

The following table lists the key tests and thresholds for the HIMatrix systems' power
supply:
IEC/EN 61131-2 Review 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 V...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.
