4 DIN rail mounting
Mounting the unit on the DIN rail
This unit should be mounted on 35 mm DIN-
rail, horizontally mounted.
Removing the unit from the DIN rail
5 Cooling
To avoid obstructing the airflow around the unit, the spacing must be at least 25 mm above and below, and 10 mm left and
right.
6 Supply voltage
XSRING+2400, XSRING+BP2400 : 10 to 60 VDC
XSRING+2230, XSRING+BP2230: 10 to 60 VDC
XSRING+2220, XSRING+BP2220 : 10 to 30 VDC
Power consumption : 6 W
The product is protected against the inversion of the polarity of the supply voltage.
7 Isolation and grounding
The enclosure of the product is metallic; It must be grounded.
The minus polarity of the supply voltage is common with the minus voltage of the electronic board –
usually called 0 V - and is isolated from the enclosure.
Moreover, the Ethernet signal and the SHDSL signal are isolated through transformers. It is why
• the versions XSRING+2400 and XSRING+BP2400 are fully isolated. The common mode voltage must not exceed 1500 V.
• The versions XSRING+2220 and XSRING+BP2220 provide the minus voltage through the RS232 interface and through
the RS485 interface.
• The versions XSRING+2230 and XSRING+BP2230 provide the minus voltage through the RS232 interface.
