WARNING
Some components inside the power supply are at AC
voltage even when the On/Off switch is in the "Off "
position. To avoid electric shock hazard, disconnect the
line cord and load and wait two minutes before removing
cover.
AC Input Wires No Conductor Pretreatment: Phoenix Contact clamping parts are designed so
that all kinds of copper conductors can be clamped without pretreatment.
It is forbidden to solder the conductors. The solder tin yields and fractures under high pressure. The
result is increased contact resistance and an excessive temperature rise. In addition, corrosion
caused by pickling or fluxes has been observed on soldered conductor ends. Notch fractures at the
transition point from the rigid to the flexible conductor area are also possible.
The power supply ON/OFF switch is not the main "disconnect device" and does not completely
disconnect all the circuits from the AC source.
An appropriately rated "disconnect device" such as circuit breaker, type B plug on power cord, ...etc.,
shall be provided in the final installation. The "disconnect device" for one phase units shall
disconnect both supply lines simultaneously. The "disconnected device" mustl be easily accessible.
3.7.1 AC Input Connector
The AC input connector is a 4-Terminal wire clamp located on the rear panel.
Phoenix-Contact P/N: FRONT4-H-7.62/4. Use suitable wires and tightening torque as follows:
1. Wire diameter: 12AWG or 10AWG.
2. Tightening torque: 4.4-5.3Lb-inch. (0.5-0.6Nm).
3.7.2 AC Input Cord
WARNING
AC input cord is not provided with power supply.
Refer to section 1.3.4 for details of the recommended AC
input cords and to section 3.7 for disconnected device
requirement.
3.7.3 AC Input Wire Connection
1.Strip the outside insulation of the AC cable approx. 10cm. Trim the wires so that the ground wire is
10mm longer than the other wires. Strip 10mm at the end of each of the wires.
2.Unscrew the base of the strain relief from the helix-shaped body. Insert the base through the
outside opening in the AC input cover and screw the locknut securely (11-14 Lb-inch.) into the
base, from the inside.
3.Slide the helix-shaped body onto the AC cable. Insert the stripped wires through the strain relief
base until the outer cable jacket is flush with the edge of the base. Tighten (16-18 Lb-inch.) the
body to the base while holding the cable in place. Now the cable is securely fastened inside the
strain relief. Refer to Fig.3-2.

Einige Komponenten innerhalb des Netzteils f hren
Netzspannung, selbst wenn der On/Off-Schalter in der
Position "Off" steht. Um die Gefahr eines elektrischen
Schlags zu vermeiden, trennen Sie es vom Netz und
warten Sie zwei Minuten, bevor Sie die Abdeckung
entfernen.
Das Netzteil wird ohne AC-Netzkabel ausgeliefert.
In Abschnitt 1.3.4 finden Sie Empfehlungen f r die zu
verwendenden AC-Netzkabel, und Abschnitt 3.7 gibt
Hinweise zur vollst ndigen Trennung des Ger tes vom
