Prior to mounting please ensure that the wall the module is to be mounted to is solid, flat, and dry.
Mark three mounting places on the wall as per Figure 1.
Drill the mounting holes. Then insert wall plugs to the holes and screw two woodscrews provided to
the two upper holes so that the distance between a woodscrew head and the wall is about 7 mm.
Remove the right-side panel that covers mounting area of the module by pulling the cover panel
forward.
Suspend the module onto the two woodscrews. Screw the woodscrew into the mounting hole (see
Figure 1) and fix the module on the wall.
It is acceptable to install the module within mounting enclosures (cabinets, boxes, etc.). If the
module and any other unit are arranged adjacently then vertical and horizontal distances between them
shall be at least 10 mm each.

Connecting the Module
Connect wires to the terminals as shown in Figure 2.
Figure 2.
External Connection Diagram
Please observe polarity while connecting the module to power supplies.
The cross section of wires should not exceed 1.5 sq. mm.
If the module, the control panel, or other equipment connected to the RS-485 interface bus are
supplied by different power supplies then couple their relevant “0V” circuits.
Unless the module is the last or the first device in the RS-485 interface bus, remove the EOL
jumper from the module’s PCB (see Figure 2)
.
Put the right-side cover panel back onto place.
