3.2 Connecting the supply voltage
Connecting the supply voltage
• Remove COMBICON connector XD1 from the device.
• Connect the supply voltage to the COMBICON connector. Observe the polarity:
– 1 = US1 = 24 V
– 2 = GND = 0 V
• Plug COMBICON connector XD1 onto the device.
⇒ As soon as one or both US LEDs are lit, the device is connected.
3.2.1 Grounding the device
The devices must be grounded in order to shield the data telegram from any possible inter -
ference and to discharge such interferences to ground potential.
Grounding the device
• Mount the module on a grounded DIN rail.
• Functional grounding of the module is achieved when the module is snapped onto the
grounded DIN rail or via clamping point 5 (functional ground – FE) of COMBICON
connector XD1 .
NOTE: Electrical voltage
The device is designed exclusively for operation with safety extra-low voltage
(SELV/PELV) in accordance with IEC 60950/EN 60950/VDE 0805. The device may only
be connected to devices that meet the requirements of EN 60950. Provide overcurrent
protection (I ≤ 5 A) in the installation.
The device is operated using a 24 V DC voltage.
