6.2.3 Installing the Indoor Lightning Arrester
For the wide-band lightning arrester that need not be grounded separately, you may
directly connect it in serial to the place between the main feeder and the indoor set top
jumper. During the installation, the lightning arrester and indoor equipment as the
cabling rack should be insulated.
For the lightning arrester that need be grounded, a lightning arrester frame should be
provided. Please refer to the assembly instructions provided by the supplier for the
assembling of the lightning arrester frame. The installation steps are as follows:
1. Install the lightning arrester on its frame in advance.
During the installation, please note that the connectors at both ends of the
lightning arrester are different: One end is a DIN male connector (DIN-M) and
the other is a DIN female connector (DIN-F). Make sure that the DIN-M
connector of all the lightning arresters installed on the frame are in the same
direction, and the DIN-F connector of all the lightning arresters are in the same
direction. The lightning arrester should be securely installed on the frame and in
close contact with the frame.
2. Fix the assembled lightning arrester to the cabling rack.
Plan the installation position carefully to make both the main feeder and the set
top jumper easily be connected to the lightning arrester and to enable easy
cabling.
The lower part of the lightning arrester frame that is secured to the cabling rack
can be adjusted according to the width of the cabling rack.
When the lightning arrester frame is installed on the cabling rack, make sure that
its DIN-M connector points to the main feeder and its DIN-F connector points to
the connection line from the jumper to the rack.
3. The lightning arrester is installed indoor. Its grounding wire should be connected
to the outdoor grounding copper bar and should not contact with the conductor
of the indoor cabling rack. The lightning arrester frame is insulated from the
cabling rack.
The installation of the lightning arrester frame is as shown in Fig. 6.2-4.
