6.2.2 Requirements on the Power Supply

Power Source
Note
PELV or SELV power source required
Only device the product with 24 VDC PELV (Protective Extra Low Voltage) or SELV
(Safety Extra Low Voltage) voltage sources. Failure to do so may result in electric shock.
If 1L and 2L are to be supplied separately (e.g., for safe switch-off of 2L), then either cen-
tral grounding must be implemented using two power supply units, or the power supply
connection must be made on the same phase. However, the use of two separate power
supply units is not mandatory.
Note
Note the following when 1L and 2L are supplied separately:
If 1L and 2L are to be supplied separately (e.g., for safe switch-off of 2L), then either cen-
tral grounding must be implemented using two power supply units, or the power supply
connection must be made on the same phase. Use of two separate power supply units is
not mandatory.
Fuse Protection
Always protect the power supply lines from the power supply unit to the first module with
a device circuit breaker or fuse. For this purpose, use a 24 VDC / max. 16 A fuse or cir-
cuit breaker with type B trip characteristics.
Note
Device damage if maximum supply current exceeded
The maximum supply current must not be exceeded. Otherwise, there is a risk of damage
to the PCB of the device and the pluggable connector.
