Repalcement
Please check if SPDs’ type and specification on the
packages and the labels are consistent with the contract.
Read this instruction carefully before using SPDs.
Contact us if there is any questions.
In case of damage cause by electrostatic, friction should
be avoid.
In case of any failure, disassembling SPDs is prohibited.

Status indication: a red
window indicates failure.
Check the status indicator. If the indicator is red, it need to be
replaced.
1.SPDs must be reliably grounded.
2.Make sure the connections between cable and terminals are firm
and correct.
3. SPDs’ quality are well controlled and strictly inspected before
delivery. If non-functional ones are found during operation, please
contact us early enough.
4.Within 5 years of delivery, any problems occurred during normal
operations can get treatments free.

Dimension
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.
L=a+b+c
In case of the main circuit broken because of a failed SPD, a
protection device such as air switch or fuse should be installed
before the SPDs. According to our tests, protection devices with a
nominal current of 100A are recommended. The cross sectional
area of the upper (for L/N connection) cable should be no less than
2
6mm and the cross sectional area of the cable for grounding should
2
be no less than 10mm .

CZLB -160 /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. Normally, it is
used in lighting protection zone 1. For better protection effect, SPDs
with different protection levels should be used downstream.

CZLB-160/440 series SPDs are delivered in single pieces. They
should be connected by a bus-bar and then you can choose any piece
for ground connection. Otherwise you need to ground all pieces.
Loosen all the screws completely before you put the bar in and then
tighten the screws except the one you chose for ground connection.
