(1).When using the SPD,you must have a reliable grounding.
(2).Check again wiring and polarity are correct before SPD energizing.
(3).The products were test strictly before leaving factory. If users find any
abnormalities in the module, please contact the nearest agent or our
company.
(4).In 5 years from the delivery date, if the product works improperly during
normal operation, we will repair or replace it without payment.
(1).Insert a screwdriver (its edge length≤6mm)into the downside
metal lock of the SPD;
(2).Push the screwdriver upwards to open the metal clip;
(3).Take the SPD out of the guide rail.
This SPD is designed for mounting on 35mm DIN guide rail.
Installation according with the following steps:
(1).Make the upside of the SPD locked into the guide rail;
(2).Push the downside of the SPD in the rail.
CZLB-EX series
(1).The SPDs adopt screw terminals;
(2).The wires are single or multiple cables with a cross section area of
1 ~ ;
(3).The length of bared wires is about 8mm,locked tightly by M3 bolt.
