6.2.2 Connecting the power supply
Cable specification
DANGER
Protective separation
The 24 V direct voltage must be configured as an extra-low-voltage with protective separation
- DVC A or PELV.
The required 24 VDC load power supply is wired to the screw-type terminal block (X1).
Use flexible cables with a cross-section of 0.25 to 2.5 mm
2
(or AWG 23 to AWG 13) for wiring
the power supply according to the maximum occurring current.
If you only use one wire per connection, a ferrule is not required. The following wire-end ferrules
are permissible: Without an insulating collar in accordance with DIN 46228, Form A, long
