INSTALLATION INSTRUCTION 

According to lightning protection zones concept, for installed at LPZ 0 -1 or higher. This surge protection is usually A installed in distribution-box or feeder bus of UPS, protecting devices or equipment downstream.

Fuse must be installed at the upstream of the Surge Protection or the lightning arrester to make sure that protected system has double protection. The value of the fuse used in a Surge Protection system should be conformed to:

1. The value of FUSE should not be larger than the max.withstand capacity of the Surge Protection's backup fuse value.

2. Under the status of the max. current in the power supply & close loop circuit available current, the fuse should be able to disconnect when overloaded or short-circuited.

Take 1 & 2 into consideration, the fuse should be as large as possible to allow the maximum surge discharge of Surge Protection.

INSTALLATION STEPS 

a. Mount the Surge Protection on 35 mm DIN rail.

b. Connect conductors, the cross-sectional area of cable (L-N) must be larger than 16mm² , and the earthing cable(N-PE) larger than 25mm² . The withstand voltage value of cable is not smaller than AC500V; ensure wiring reliable.

c. After above, switch on the power supply and turn on the circuit breaker, test the Surge Protection does not fault appear, this indicates the unit is operating normally.

Regularly inspect the operating status, especially after lightning. Once the fuse upstream break, or the Surge Protection’s fault appear, electrician should check/replace the SPD. 

WARNING:  

1. The device must be installed by electrically skilled person, conforming to national standards and safety regulations. 

2. It is recommended that installation should be done under power off condition.
