Before installation, confirm that the work environment meet the
installation require, including the power needs and abundant
space. Whether it is close to the connection equipment and other
equipments are prepared or not.
1. Avoid in the sunshine, keep away from the heat fountainhead or
the area where in intense EMI.
2. Examine the cables and plugs that installation requirements.
3. Examine whether the cables be seemly or not according to
reasonable scheme.
4. Power: 12 ~ 48VDC
5. Environment: Working Temperature: -40～75℃
Relative humidity 5%～95%
DIN Rail Installation
In order to use in industrial environments expediently, the product
adopt 35mm DIN-Rail installation, the installation steps as below:
1. Examine the DIN-Rail attachment
2. Examine DIN Rail whether be firm and the position is
suitability or not.
3. Insert the top of the DIN-Rail into the slot just below the stiff
metal spring.
4. The DIN-Rail attachment unit will snap into place 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. It should have corresponding simple signal at both sides of the
cable for maintaining.
