ATTACHING THE AC INPUT POWER CONNECTOR TO POWER
SUPPLY UNIT (PSU)
1. Mount the PSU to the backside of the EDGE mounting plate as shown in
.
Use 2 each of M4 hardware consisting of pan head screws, flat washers and nylon
locknuts. Make sure the PSU is mounted vertically with the 24V dc outlet wire on
the bottom.
2. Each PSU includes the mating connector for the ac cord in the box. Open the bag
and carefully remove the contents. Choose the correct cable sealing compression
grommet for the size of cable being provided. This is indicated on the side of the bag.
See
Figure 4.
3. Assemble the compression clamp, the correct size cable compression grommet and
the connector back shell onto the cable in the order and orientation shown in
Figure 5
.
4. Strip back the outer cable sheath 1 inch (25 mm) and strip each core wire 1/4 inch
(6 mm) — see
Figure 5.
5. Twist the wire elements and insert each wire into its correct location in the
connector front after slackening the core wire clamp screws. Typically the wires will
be black to “L”, white to “N” and green to ground symbol on connector front. See
Figure 6
.
6. Hold the front of the connector very firmly with dry fingers and screw on the
connector backshell. Do not use tools or you will overtighten and break the
connector. Firmly hand tight will achieve a good IP65 seal. See
Figure 7
.
7. Push the cable sealing compression grommet into the connector backshell fingers.
See
Figure 8
.
8. Hold the connector backshell firmly with fingers and screw the compression clamp
onto the connector backshell. A firm hand tightening will achieve a good seal to
IP65. Do not use tools as you are likely to damage or overtighten the connector. See
Figure 9
.
9. Attach this female connector onto the mating male connector on the end of the ac
lead cable on the PSU by turning it slowly until it fits on and turning the locking
bayonette ring through half a turn. See
Figure 10
.
10. Apply ac power to the incoming ac power cable and test the 24V dc output by
plugging a Gen III Serial Edge Device onto the dc cable from the PSU.
