To connect grounding cable to the metal heatsink of the product, Kerlink recommends using
tongue terminals. Those terminals must be tightened with wing nuts.
Regarding the DC surge protection integration process inside the Wirnet iBTS enclosure,
Kerlink recommends using the following guideline:
1.
DS71R-48DC must be inserted on the left side of the UC module.
The mechanical holding must be ensured by using a double face tape.
Note: It is important to avoid any enclosure deformation which may imply ingress
protection issue.
2.
The M25 cable gland must be used to introduce the power supply cable inside the
enclosure. As mentioned on the installation guide of the Wirnet iBTS product, the
external cable diameter must be between 5 to 8 mm to insure a good ingress
protection.
The power supply cable is a 1.5 sq. mm cable.
3.
The positive wire of the power supply cable must be connected to the surge
protector and then to the Wirnet iBTS connector.
4.
The negative wire of the power supply cable must be connected to the Ground side
of the surge protector.
5.
A ground connection must be done between the ground side of the surge protector
and the metal heatsink of the product. The best solution is to use tongue terminal.
6.
A ground connection must be done between the metal heatsink of the product and
the Wirnet iBTS connector.
