The recommended cable section is 1.5 sq. mm.
The auxiliary power supply connector is a Euroblock plug, which is located on the front side
of the CPU module. The polarity of the power signals are indicated besides the connector, as
shown below:
Figure 158 : Auxiliary DC power supply connector
First, the auxiliary power supply cable must be introduced into the enclosure through a cable
gland. The operator needs to determine which cable gland can be used for this operation:
M25 cable gland can be used for that purpose if the Ethernet cable is no longer
required (LTE backhaul only).
If the Ethernet cable is required, then a M16 cable gland must be used. One M16
blind stops must be removed and replaced by the M16 cable gland.
Note 1:
The M16 cable glands are not provided by KERLINK.
The M25 cable gland allows external cable diameter from 5mm to 8 mm.
The M16 cable glands allows external cable diameter from 4mm to 8 mm.
After insertion through the cable gland, the 2-wire cable can be screwed to the dedicated
Euroblock plug as described on the Figure 158, according to the defined polarity.
Note 2:
the Euroblock plug must be inserted into the Euroblock receptacle only once all
other connections are settled and USIM card inserted (see §4.7).
Note 3:
the external power supply must be a limited power source.
