Installation

Connections between ACPZ boards (frequency converters or parallel UPSs with SSC)

Connections between each rectifier-inverter cubicle and the Static Switch Cubicle (example

of 3 parallel UPS rectifier-inverters with SSC)

– these connections are made through the special cables supplied;

– these connec tions only concern installations with a Static Switch Cubicle and should be made in addition to the connections

between rectifier-inverter cubicles described previously;

– the ribbon cable from connector XM133 of the ACPZ board of one rectifier-inverter cubicle is connected to one of the

connectors XM127 to XM132 of the ACPZ board of the Static Switch Cubicle.

Important:

Outside the cubicles, group the APOZ inter-board and ACPZ inter-board connections with the inter-cubicle auxiliary

connections, and separate this assembly from the power cables.
