2. Assembly and installation
2.1 Precautions for installation
Wrong wiring will lead to breakdown of the instrument or electrical shock,
please read the operating manual clearly before installation.
a. Make sure to remove AC power to the controller before wiring input and output
connections, and before opening the controller housing.
b. The installation site of the controller should be well ventilated and avoid direct
sunlight.
c. Relay contacts are subjected to electrical erosion. Do not connect relay contacts
directly to heavy loads, connect a magnetic switch instead. Especially with
inductive and capacitive loads, the service life of the contacts will be reduced.
d. For suppression of sparks and arcing, components such as RC combinations,
nonlinear resistors, series resistors, diodes and varistors are used.
2.2 Installation of controller
Reserve a 135x 135mm hole on the front panel of the wall mount chassis and
insert the controller from the front of the chassis, fasten the fixed support to fix the
controller.
