2.4 Location, Mounting And Cooling

This power supply is fan cooled. The air intake is at the front panel and the exhaust is at

the rear panel. Upon installation allow cooling air to reach the front panel ventilation inlets.

Allow minimum 10cm (4Inch) of unrestricted air space at the front and the rear of the unit.

The power supply should be used in an area that the ambient temperature does not exceed

+50ºC.

The D750 can be operated from a nominal 85V to 265V, single phase, 47~63Hz. The input

voltage range and current required for each model is speciﬁed in Chapter 2. Ensure that

under heavy load, the AC voltage supplied to the power supply does not fall below the

speciﬁcations described in Section 1.3.

Connection of this power supply to an AC power source should be made by an electrician

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.

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

The rear panel can be connected to AC power through AC and Euroblocks, and the ground

wire must be connected to ground for safe grounding.
