Power Supply; Safety Wiring - Delta DVP-SE Series Instruction Sheet

 Dimension & Installation
Please install the PLC in an enclosure with sufficient
space around it to allow heat dissipation, See
[Figure 3].
 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.
 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-SE is DC. When operating DVP-SE please note the following
points:
1. The power is connected to two terminals, 24 VDC and 0 V, and the range of power is
20.4 to 28.8 VDC. If the power voltage is less than 17.5 VDC, the PLC will stop
running, all outputs will go "Off", and the ERROR 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).
 Safety Wiring
Since DVP-SE is only compatible with DC power supply, Delta's power supply modules
(DVPPS01/DVPPS02) are the suitable power supplies for DVP-SE. We suggest you
install the protection circuit at the power supply terminal to protect DVPPS01 or
DVPPS02. See the figure below.
