3.5. 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 a
minimum of 10cm (4 Inch) 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
+50°C.
3.6. AC Source Requirements
Depending on its input option, the Genesys
TM
3300W series can be operated from a nominal
190V to 240V. 50/60Hz single phase, and three phase 200V models and 380-415V, 50/60Hz for
three phase 400V models. 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 Chapter 2.
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. for single phase models, or 20A max for three phase models.
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
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 shall comply with
UL/IEC 60950-1 requirements and shall be easily accessible.
3.7.1. AC Input Connector
The AC input connector is a wire clamp located on the rear panel. Use suitable wires
and tightening torque as follows:
1. Wire diameter: 12AWG for single-phase models.
14AWG for three-phase 200V models and
16AWG for three-phase 400V models. Refer to Table 1-2 for details.
2. Tightening torque: 10.7-13.4Lb-inch. (1.2-1.5Nm).
