about 2 mm to allow room for sliding the Modbus gateway
between the wall and the screws.
5. Before tightening the screws into the wall, make sure the
screw head and shaft size are suitable by inserting the
screw through one of the keyhole-shaped apertures of
the gateway.
6. Once the screws are fixed in the wall, hang the Modbus
gateway on the 2 screws through the large opening of the
keyhole-shaped apertures, and then slide the switch
downwards. Tighten the two screws for added stability, as
shown below.
Wiring Requirements
Cable laying need to meet the following requirements,
1. It is needed to check whether the type, quantity and
specification of cable match the requirement before
cable laying;
2. It is needed to check the cable is damaged or not, factory
records and quality assurance booklet before cable
laying;
3. The required cable specification, quantity, direction and
laying position need to match construction requirements,
and cable length depends on actual position;
4. All the cable cannot have break-down and terminal in the
middle;
5. Cables should be straight in the hallways and turning;
6. Cable should be straight in the groove, and cannot
beyond the groove in case of holding back the inlet and
outlet holes. Cables should be banded and fixed when
they are out of the groove;
7. User cable should be separated from the power lines.
Cables, power lines and grounding lines cannot be
overlapped and mixed when they are in the same groove
road. When cable is too long, it cannot hold down other
cable, but structure in the middle of alignment rack;
8. Pigtail cannot be tied and swerved as less as possible.
Swerving radius cannot be too small (small swerving
causes terrible loss of link). Its banding should be
moderate, not too tight, and should be separated from
other cables;
9. It should have corresponding simple signal at both sides
of the cable for maintaining.
