Wiring Procedures
Use crimp terminals for wiring; use 26-14 AWG wire (0.13 mm
2
–3.31 mm
2
) for all wiring purposes.
1.
Strip the wire to a length of 7±0.5mm (0.250–0.2.08 inches).
2.
Unscrew the terminal to its widest position before inserting a wire.
3.
Insert the wire completely into the terminal to ensure that a proper connection can be made.
4.
Tighten enough to keep the wire from pulling free.
To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).
Do not use tin, solder, or any other substance on stripped wire that might cause the wire strand to break.
Install at maximum distance from high-voltage cables and power equipment.
Wiring Power Supply
Connect the "positive" cable to the "+V" terminal, and the “negative” to the "0V" terminal.
Earthing the Power Supply
To maximize system performance, avoid electromagnetic interference by:
Mounting the module on a metal panel.
Earthing the module’s power supply: connect one end of a 14 AWG wire to the chassis signal;
connect the other end to the panel.
Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length. However, it is
recommended to earth the module in all cases.
