Wrong wiring will lead to breakdown or electrical shock of the instrument, please read this
operation manual clearly before installation.
zMake sure to remove AC power from the controller before wiring input, output connections,
and remove it before opening the controller housing.
zThe installation site of the controller should be good in ventilation and avoid direct sunshine.
zThe material of signal cable should be special coaxial cable. Strongly recommend using our
coaxial cable. Do not use normal wires instead.
zAvoid electrical surge when using power. Especially when using three-phase power, use
ground wire correctly.
3.Assemblyandinstallation
3.1 Controller installation: This controller can be installed through panel mounting, wall
mounting and pipe mounting.
Installation of panel mounting: First,prepare a square hole of 138 x 138mm on the panel box,
and then insert the controller directly into the panel box. Insert the accessorial mounting
bracket from the rear, and make it be fixed in to pickup groove.
