3.7 AC INPUT POWER CONNECTION

CAUTION

Connection of this power supply to an AC power source should be made by an electrician or other qualified personnel

The power supply shall be connected to the AC source via protective device (circuit breaker, fuses, etc.) rated 30A max..

WARNING

There is a potential shock hazard if the power supply chassis (with cover in place) is not connected to an electrical safety ground via the safety ground in the AC input connector.

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.

The power supply ON/OFF switch is not the main disconnect device and does not completely discon- nect 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 shall comply with UL/IEC 60950-1 re- quirements and shall be easily accessible.

3.7.1 AC Input Connector

The AC input connector is a header (Phoenix Contact P/N:PC6-16/4-GF-10,16) with a screw plug in connector (Phoenix Contact P/N:PC 6/4-STF-10,16), located on the rear panel.

Use suitable wires and tightening torque as follows: 1. Wire diameter:.

12AWG for three-phase 200V models and

14AWG for three-phase 400V models. Refer to Table 1-1 for details.

2. Tightening torque: 10.7-13.4Lb-inch. (1.2-1.5Nm).

3.7.2 AC Input Cord

WARNING

The AC input cord is not provided with the power supply

Refer to Section 1.3.4 for details of the AC input cords and to section 3.7 for disconnected device requirement.

3.7.3AC Input Wire Connection

1.Strip the outside insulation of the AC cable approx. 10cm (3.94 inches). Trim the wires so that the ground wire is 10mm longer than the other wires. Strip 10mm (0.4 inches) at the end of each of the wires.
