1. Overview
DC power surge protectors are mainly used for C-level protection of DC power distribution systems. They
are used to protect electrical and electronic equipment from lightning electromagnetic pulse induced voltages,
operating transients and resonance (<100μs) overvoltages. They are widely used in communication equipment,
power protection in electrical, electrical appliances, power equipment, security monitoring, transportation,
industrial control, aviation and other fields. This series of products has the characteristics of extremely fast
response time, built-in thermal protection, low residual voltage, timely tripping, etc., and the flame retardant
level reaches V-0 level, which can prevent fires to the greatest extent and provide safety protection.
2. Safety guide
Only professional and technical personnel are allowed to install, maintain and replace lightning protection
products according to this manual.
Installation must be carried out in the case of power failure.
Please check the working status of the lightning arrester regularly, and replace it in time if the lightning
arrester fails.
Surge protector and circuit breaker should keep a distance of 3-18cm.

Please make sure it is indoors or in a waterproof box.
Avoid direct sunlight.
Avoid installing in places with severe vibration, it should be installed on DIN35mm rail.
Make sure that the working voltage of the surge protector complies with the mains working voltage.
Ensure that the lightning arrester can be reliably grounded, and the power frequency grounding resistance
is lower than 10 ohms.

7. Malfunctions
Malfunctions
Reasons
Solutions
The display window of the SPD is
red.
The lightning protector is damaged by
lightning strike or other external force.
Contact the lightning protection manufacturer
or agent to replace the lightning protection
device.
After the remote signal is
connected, the alarm or the line is
disconnected.
The remote signal wiring is wrong or the
lightning protector is damaged.
Please refer to the instruction manual to adopt
the correct remote signal wiring method or
confirm whether the lightning protector is
damage.
Circuit breaker trips frequently.
The parameters of the circuit breaker
do not match/the leakage current of the
surge protector is too large.
Replace circuit breaker/replace lightning
protector.
