ZGG40-275 Modular Power Supply SPD
Product Specification
General
The ZGG40-275 Modular Power Supply SPD can be used for protection of L-N and L/N-PE. It is applied in the
low voltage AC power distribution system, and connected between AC power supply and system equipment in
parallel. It can prevent equipment from the impulse surge and transient overvoltage caused by the outside
environment (such as lightning, EMI, etc.) or by the system (such as switching effects of the system, startup or
shutoff of the inductance and capacitance load, etc.).
Features
1
Anti-reverse slot design;
2
High discharge capacity and low residual voltage;
3
Overtemperature protection;
4
Failure indication and remote signalling alarm dry contacts.

Installation, Usage and Maintenance
Installation
1
This product can only be installed and maintained by qualified professionals. The installation position
cannot be touched by hands. Ensure that it is uncharged and check whether the SPD is all right before
installation. If there’s damage or the display window is red, the SPD can not be used any more; if the
window is green, the SPD is normal.
2
The SPD should be installed behind the fuse (FU1) of the power supply circuit, with the capacity of the
fuse not exceeding 125A gL/gG; otherwise an 80A gL/gG fuse (FU2) should be provided in the surge
protection branch circuit.
3
Refer to Fig. 3 for connection, according to the marks on the SPD. The sectional area of the connecting
wire must be more than 4mm2, as short as possible.
4
Connection of remote signalling alarm: the SPD is provided with remote signalling interfaces (1 and 2
normally closed, and 2 and 3 normally open), applicable for remote monitoring or alarm.
5
After the connection, check if the module is fitted in. If so, 1 and 2 are closed, and 2 and 3 are open; if not,
repress the module.

Usage and Maintenance
1
After failure, the ZGG40-275 Modular Power Supply SPD shall be automatically disconnected with the
power supply circuit through the internal thermal fuse system, the display window changes to “Red” from
“Green”, and remote signalling interfaces 1 and 2 are open and 2 and 3 are closed. When the degradation
display window is “Red” or there’s a remote alarm signal, the SPD should be changed immediately.
