To Replace The Cable - Montarbo W28As Instruction Manual

28A - 24A
Important !
Wiring of the power cable for the PowerCon
connector (supplied with the unit).
The power cord assembly must be made by a qualified techncian in
compliance with the national regulations in force for electrical systems.
Strip the cable for 20 mm of length and strip each wire for 8 mm of
length. We suggest to use a power cable with 2,5 mm
wires (the insert terminals can however support a cable with wires up
to a section of 4 mm 2 /12AWG).
Insert the power cable into the bushing and into the chuck (white
chuck for a cable diameter of 5 ÷ 11 mm; black chuck for a cable
diameter of 9.50 ÷ 15 mm). Insert the wires into the terminals and
fasten the clamping device by a flat screw driver.
The wire ends can be clamped in or soldered to the terminal, always
paying attention to the symbols shown on the connector:
L (Live - corresponding to the brown wire),
N (Neutral - corresponding to the light blue wire) and
(Ground - corresponding to the yellow and green wire).
Once the wires have been connected to the insert, lead the cable
through the housing and screw down the bushing by means of a 3/4"
fork wrench (min. torque 2.5 Nm / 1.8 lb-ft).
The cable must comply with the applicable, country specific, safety
regulations.
The minimum conductor size must be:
2.5 mm (13 AWG) for the cable wired to the NC3 MPA (AC line in) plug
2
1.5 mm (15 AWG) for the cable wired to the NC3 MPB (AC loop out)
2
plug.
The mains power plug on the other end of the cable must be certified
for a current equal to 20A at least (eg: IEC309 32A).
When, for any reason, the power cable show signs of damage, it is
mandatory to replace or repair it before any further use.

To replace the cable:

1 - disconnect the cable at both ends
2 - unscrew the bushing (3/4" wrench)
3 - using a screwdriver, disconnect all three conductors from the insert
4 - remove the chuck and the bushing from the cable
5 - using a new cable, complying with the previous reported require-
ments, proceed with the connector's assembly, as described above.
CAUTION:
- Before plugging and/or unplugging the PowerCon connector, it is
mandatory to switch off all the equipment that is connected to the
cable and to disconnect the cable from AC mains.
- Follow this procedure also when the speakers must be moved.
Operate as illustrated in the side drawing when you have to plug and/or
unplug the connector.
