(1).Before using, SPD must have a reliable grounding.
(2).Before using, please check again whether the module's EX-proof rating
accords with the operating ambient, and wiring and polarity are correct. If
working with flameproof transmitter, live action is not allowed.
(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.
CZLBX-48-S series
Note:The wires connect SPD to protected device shoud be as short
as possible, and reduce bending. When use the earthing terminal
connect to ground, please cut the yellow-green lines and keep it
alignment.
