3.7.1ACInput Connector
3.7.2ACInput Cord
3.7.3ACInput Wire Connection
TheAC input connector is:for single phase: Phoenix Contact P/N: PC6/3-STF-10,16
forthree phase: Phoenix Contact P/N: PC6/4-STF-10,16
Header :for single-phase: Phoenix Contact P/N: PC6-16/3-GF-10,16
forthree-phase: Phoenix Contact P/N: PC6-16/4-GF-10,16
Use suitablewires and tightening torque as follows:
1. Wire diameter: 12AWG forsingle-phase models,
14AWG fo rthree-phase 200V models and
16AWG fo rthree-phase 400V models. Refer to Table1-2 for details.
2. Tightening torque: 10.7-13.4Lb-inch. (1.2 -1.5Nm).
Refer to section1.3.4 for details of therecommended AC input cords and to section3.7 fo
r
disconnected device requirement.
1.Strip the outside insulationoftheAC cable approx. 10cm. Trim thewiressothat theground wire is
10mm longer than theother wires. Strip 10mm at the end of each of thewires.
2.Unscrew the base of thestrain relief fromthe helix-shaped body.Insertthe base through the
outside opening in theACinput cover and screw thelocknut securely(11-14 Lb-inch.)intothe
base, fromthe inside.
3.Slidethe helix-shaped body ontothe AC cable. Insertthe stripped wiresthrough thestrain relief
WARNING
AC input cordis not provided with power supply.
WARNING
Some componentsinsidethe power supplyare at AC voltage even whenthe On/Offswitch is in the
“Off”position.Toavoid electric shock hazard, disconnect the line cord and load and waittwo
minutes beforeremovingcover.
The power supply ON/OFF switch is not themain “disconnectdevice”and does not completely
disconnectall the circuits fromtheAC source.
An appropriately rated“disconnect device”suchas circuit breaker, typeBplugonpower cord, ...etc.,
shallbeprovided in the final installation. The “disconnectdevice” for onephaseunits shall
disconnect bothsupply lines simultaneously. The “disconnected device”must be easily accessible.
CAUTION
AC Input WiresNo Conductor Pretreatment:PhoenixContact clamping parts are designed
so
that all kinds of copper conductors canbe clamped without pretreatment.
It is forbidden to solder theconductors. The solder tin yieldsand fractures under high pressure.
The
result is increased contact resistance and an excessive temperature rise.Inaddition, corrosio

the
transition point fromthe rigid to the flexible conductorareaare also possible.
