Power Supply
The following table lists the key tests and thresholds for the device's power supply:
IEC/EN 61131-2
Review of the DC supply characteristics
Alternatively, the power supply must comply with the following stan-
dards:
IEC/EN 61131-2 or
SELV (Safety Extra Low Voltage) or
PELV (Protective Extra Low Voltage)
HIMax devices 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.
Backup duration withstand test:
Test B, 1000 h

ESD Protective Measures
Only personnel with knowledge of ESD protective measures may modify or extend the
system or replace a module.
NOTE
Electrostatic discharge can damage the electronic components within the control-
lers!
When performing the work, make sure that the workspace is free of static, and
wear an ESD wrist strap.
If not used, ensure that the module is protected from electrostatic discharge, e.g.,
by storing it in its packaging.
Only personnel with knowledge of ESD protective measures may modify or extend
the system wiring.
2.1.4
Requirements to be met by the operator and the machine and system
manufacturers
The operator and the machine and system manufacturers are responsible for ensuring that
HIMax systems are safely operated in automated systems and plants.
The machine and system manufacturers must validate that the HIMax systems are correctly
programmed.
2.2 Residual
Risk
No imminent danger results from a HIMax system itself.
Residual risk may result from:
Faults in the engineering
Faults in the user program
Faults in the wiring
