53.2
Please install the PLC in an enclosure with sufficient space around it to allow heat
dissipation. See [Figure 5].
 Direct Mounting: Use M4 screw according to the dimension of the product.
 DIN Rail Mounting: When mounting the PLC to 35mm DIN rail, be sure to use the
retaining clip to stop any side-to-side movement of the PLC and reduce the chance of
wires being loose. The retaining clip is at the bottom of the PLC. To secure the PLC to
DIN rail, pull down the clip, place it onto the rail and gently push it up. To remove the
PLC, pull the retaining clip down with a flat screwdriver and gently remove the PLC from
DIN rail. See [Figure 6].
 Wiring
1. Use 22-16AWG (1.5mm) single or multiple core wire on
I/O wiring terminals. See the figure in the right hand side
for its specification. PLC terminal screws should be
tightened to 1.90 kg-cm (1.65 in-lbs) and please use only
60/75ºC copper conductor.
2. DO NOT wire empty terminal. DO NOT place the I/O signal cable in the same wiring
circuit.
3. DO NOT drop tiny metallic conductor into the PLC while screwing and wiring. Tear
off the sticker on the heat dissipation hole for preventing alien substances from
dropping in, to ensure normal heat dissipation of the PLC.
 Power Supply
The power input of DVP-SV/SV2 is DC. When operating DVP-SV/SV2, note the
following points:
1. The power is connected to two terminals, 24VDC and 0V, and the range of power is
20.4 ~ 28.8VDC. If the power voltage is less than 20.4VDC, the PLC will stop running,
all outputs go "Off", and the ERROR LED indicator will start to blink continuously.
2. The power shutdown for less than 10ms will not affect the operation of the PLC.
However, the shutdown time that is too long or the drop of power voltage will stop the
operation of the PLC, and all outputs will go off. When the power returns to normal
status, the PLC will automatically resume the operation. (Please take care of the
latched auxiliary relays and registers inside the PLC when doing the programming).
