  • Page 84: External Dc Power Equipment

    The MFA150 Modular Power System and the System 600 Power Plant are considered “external” power equipment because they are not housed in Meridian 1 columns. DC-powered systems generally require one input receptacle per rectifier, within 1.8 m (6 ft) of each rectifier. The commercial power receptacles required are determined by the number and type of rectifiers used.
  • Page 85 System 600/48 Power Plant The System 600/48 Power Plant is a positive ground, –48 V dc, 600-A power plant. It can be used with all Meridian 1 DC-powered systems, but is optimized for larger system configurations such as system options 71, 81, and 81C.

NT6D53 Junction Box If a rectifier is positioned at a distance from the Meridian 1, the NT6D53 Junction Box can provide an interim connection between the rectifier and the field wiring terminal block in the pedestal. One junction box supports one column.

Allow enough slack in the wiring to allow tracing and to reconnect wires if they break at the terminal. Extend incoming wiring (such as cables from the central office or wiring from a recorded announcement machine) to the MDF and terminate them on separate connecting blocks.

Cabling for the whole backplane can be expanded using four NT8D81AA Cable/Filter Assemblies. Note: Backplane slots 0, 4, 8, and 12 (for cables A, E, K, and R) are already fully cabled for 24 pairs, so no change is required to those slots.

    If the customer supplied equipment is not configured with a Low Voltage Disconnect feature that disconnects power to the load after severe discharging of the batteries, then this Trip signal may be used to trip the Meridian 1 circuit breakers and initiate a line transfer.

  • Page 514: Recommended Features On Customer Supplied Power Equipment

    Typically a disconnect voltage is 42 Volts DC, to provide adequate protection of batteries. When the AC input voltage returns and the batteries are sufficiently recharged, the Meridian 1 power can be restored by switching the Meridian 1 circuit breakers.
