【
The Method of Maintenance
】
This product is connected in series. The surge protection
device is installed in the front end of the protected
equipment. The “IN” of the surge protection device is the
input side, and the “OUT” is the output side. That is, the
external signal cable is connected to the “IN (Line)” end
of the surge protection device, The protected device is
connected to the “OUT (Equip)” end of the surge
protection device;
The length of the connection line between the protected
equipment and the surge protection device should not
exceed 0.5 meters, it is better that the surge protection
device is closer to the protected equipment;
The PE line of the surge protection device is connected
to the equipotential bonding terminal of the protected
device first, and then reliably connected with the
grounding network of the lightning protection system.
The connection line is required to be short, thick and
straight;
The components in the surge protection device are
strictly tested. Normally, no special maintenance is
required. The surge protection device should be
regularly tested during use. Remove the surge protection
device during fault detection. The resistance between
the input and output should be
≤
11
Ω
, and the
resistance between the core line and ground should be
≥
10
ΜΩ
.If there is a fault, it should be repaired or
replaced in time to ensure the safety of the equipment.
