2.1 Standard 35mm DIN slot installation
◆Fixed installation guide rails;
◆Open the DIN snap-fit at the bottom of the module and fix the bottom
of the module to the DIN guide
◆Insert the module into the expansion socket of the front module one
by one;
◆Push up the side latch to fix with the front module, and fix the module
to the guide rail by pushing up the latch.
*Checking carefully that the DIN snap-fit is tightly fixed to the DIN guide
rail, as shown in Figure

2.2 Panel installation
The screws (M3 optional), must be used to fix the module in situations
with high vibration. Positioning and drilling the installation holes according to
the dimensions shown in Figure 2-2, and use the suitable screws to fix the
module on the backplane.
2.3 Cable connection and specification
It is recommended to use shielded twisted-pair cables and prefabricate
insulated terminal ends to ensure the quality of the wiring. The following
table lists the cross-section and models of the recommended cables.

position and 0.5 ~ 0.8Nm tightening torque, to ensure reliable connection
without damaging the screw.
2.4 Wiring requirement
For the safety (to prevent electric shock and fire accidents) and lower
noise, the ground terminal of the controller should be connected in
accordance with the requirements from national electrical regulations, and
the ground resistance should be less than 100 Ω . Single point grounding
should be used when wiring multiple controllers, and the ground wire cannot
form a loop. As shown in the diagram below:
