MX28B600-48V

Prior to installation, drawings, floor loading requirements, external alarm points, AC service entrance, and grounding schemes should all be checked and confirmed. If batteries are to be mounted in a room separate from the power plant, careful attention should be paid to battery cable voltage drop effects. Environmental operating temperatures and ventilation/cooling considerations should also be noted, not just for the power system but for all other equipment that may reside in the power room area.

5.1.6 Mounting

Front mounting on standard 23” rails, and/or installation in appropriately vented cabinets is possible.

5.1.7 Ventilation

The rectifiers have fans that provide front to rear airflow for internal cooling. The MX28B600 housing should be installed and/or mounted such that there is free airflow to the front, top, and bottom of the unit. [Refer to Section 4.9 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 been removed including any battery sources before proceeding.

The MX28B600 DC power plant requires the supply of 208/220/240V AC, single-phase, 50/60 Hz power through individual external 20-amp two-pole circuit breakers to the AC input terminal block connections for each rectifier in the system. (The AC wiring, from the AC input terminal block connections to the hot-pluggable AC input connector for each rectifier, is factory installed.)

The AC input enclosure, located at the top left rear of the MX28B600 housing, is provided with three one-inch conduit entry holes. Inside, 3 terminal strips for AC input power connection and a separate “Earth Ground” bar for connection of the safety ground wires are provided. The terminal blocks are labeled as Position 1 through Position 4 for shelves 1, 2, and 3 with each position having inputs designated “L1” and “L2” for connection of the two AC wires. Positions 1-4 correspond to the respective rectifier shelf positions from left to right.

The suggested wire size is #10 AWG rated at 90°C or higher; however, the ambient temperature and number of wires in a conduit must also be considered in accordance with NEC requirements. It is suggested that feeds for four rectifiers (8 wires) and one safety ground wire be run in a one-inch conduit; however, be sure to follow any local electrical wiring codes.

If the AC input power is provided from a three-phase distribution panel, the circuit breaker positions should be selected such that the load is balanced as much as possible.

5.3Battery Connections

An external circuit breaker or fused disconnect (Customer supplied) is recommended in the negative line (located at the battery end of the related cables) to protect the cables from the battery to the MX28B600 DC power plant. The power plant can monitor auxiliary contacts from this breaker.
