microSD Card Installation and Removal
▪
Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing
the microSD card.
1.
To install the microSD card slide it
into the slot as shown in the
accompanying figure, until the card
clicks into place.
2.
To remove the card, press it into its
slot lightly, the spring ejects it.
Wiring
▪
This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power
environments.
▪
All power supplies in the system must include double insulation. Power supply
outputs must be rated as SELV/PELV/Class 2/Limited Power.
▪
Do not connect either the ‘Neutral’
or ‘Line’ signal of the 110/220VAC to device’s 0V
point.
▪
Do not touch live wires.
▪
All wiring activities should be performed while power is OFF.
▪
Use over-current protection, such as a fuse or circuit breaker, to avoid excessive
currents into the power supply connection point.
▪
Unused points should not be connected (unless otherwise specified). Ignoring this
directive may damage the device.
▪
Double-check all wiring before turning on the power supply.
C
aution
▪
To avoid damaging the wire, do not exceed a maximum torque of:
- All terminal blocks except T42
outputs’ terminal block: 0.5
N·m (4.4 in-lb).
-
T42 outputs’ terminal block (with smaller pitch): 0.2
N·m (1.8 in-lb).
▪
Do not use tin, solder, or any substance on stripped wire that might cause the
wire strand to break.
▪
Install at maximum distance from high-voltage cables and power equipment.
Wiring Procedure
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm
2
–
3.31 mm
2
)
1. Strip the wire to a length of 7±0.5mm (0.250
–
0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.
