Maintenance
1.Check the status indicator. If the indicator is red, replace the SPD
or the failed module.
4. Within 5 years of delivery, any problems occurred during normal
operations can get treatments free.
3. SPDs’ quality are well controlled and strictly inspected before
delivery. If non-functional ones are found during operation, please
contact us early enough.
2. Check if the connections are correct and reliably fixed before
powering on SPDs.

Installation
Dimension
A single module has a thickness of 18.0mm.
CZLB-80/440 Serie SPDs use a bus-bar to short terminal PE/N.
Please insure the bus-bar is well connected before mounting(figure
blow). While loosing or tightening the screws, hold the bus-bar in
case it drops. If the bus-bar got lost, every piece of the module must
be connected to PE/N separately.
In case of the main circuit broken because of a failed SPD, a
protection device such as fuse should be installed before the SPDs.
Protection devices with a suitable nominal current should be selected
according to the Parameter table. Corresponding cross sectional
area of the cable for L/N and PE connection should also be selected
according to the Parameter table.
L=a+b+c
When install SPDs, the connection cable should be as short as
possible. As the diagrams shown below, L( in normal
connection) should be less than 0.5 meters. Cable between SPD and
the protected device should be less than 10m. The housing of the
protected device should be grounded via SPD terminals.

Typical applications
Single phase system
Main technical parameters
CZLB-80/440 series AC power supply SPDs are designed
according to the domestic criterials. It enables the connection
between the power supply system and an equipotential network
instantaneously when the surge occurs and limit the residual voltage
to a certain level to protect the devices protected.
