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 connections 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.
