1.4Installation of an External Maintenance Bypass

When an external maintenance bypass is installed, a normally open, voltage free contact must be available. This contact must be connected to the connector M4, Pin1 and Pin 2 at the top left hand corner of the mother board for the inverter/bypass electronics (IBYBP-CP see figure 1.10.3).

If the standard SOLA no-break wall-mounted maintenance bypass switch is used (optional) in the MB3 cabinet, a normally open contact is provided.For the version 2 maintenance bypass (3 position), an additional contact is provided which automatically isolates the UPS system (EPO) when switched to the "UPS ISO- LATED" position (see FIG 1.4.2).
