5.1.7Ventilation

The rectifiers have fans that provide front to rear airflow for internal cooling. The MX28B1200 housing should mounted to allow free airflow from the front and out the top of the unit. [Refer to Section 4.10 for environmental characteristics.]

5.2AC Service and Ground Connections

*****WARNING *****

Ensure that all of the DC and external AC circuit breakers are in the OFF position prior to connecting service to the power plant. Confirm that all voltages have be en removed including any battery sources before proceeding.

The MX28B DC power plant requires the supply of 208/220/240V AC, single -phase, 50/60 Hz power through individual external 80-amp circuit breakers to the AC input terminal block connections for each rectifier shelf the system. Each rectifier shelf has four 20-amp breakers, each serving one rectifier. The AC Grounding wiring, from the Earth terminal block to the individual shelves is factory installed for each shelf installed. Connections to the AC input connector for each rectifier, is factory installed.
