WIRING OF THE POWER CABLE FOR THE powerCON
®
(SUPPLIED WITH THE UNIT).
the power cord assembly must be made by a qualified technician 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
2
section 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 with a flat-blade screwdriver.
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 blue wire) and
(Ground - corresponding to the yellow-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
2
(13 aWG) for
the cable wired to the nC3 mPa (aC line in) plug and 1.5 mm
2
(15 aWG)
for the cable wired to the nC3 mPB (aC loop out) 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 requirements,
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.
