Tie cabinets
The Tie Cabinets (TCs), provided by UPS manufacturer, has input connections up to three
parallel UPS modules. It is also possible to use two redundant UPS modules and one bypass
connection. This bypass option can be used for service or test purposes.
Note!
It is not allowed to feed the load simultaneously from mains (bypass) and
inverter(s) of the UPS unit(s). While turning the switch, where the bypass is
connected, ON/OFF, UPS should be on static bypass mode or shut down.
Note!
The maximum load supported by the system is limited to 15 kVA if there are two
UPSs and bypass connected to TC (See wiring diagrams below).
Terminals of the TC have two-wire connection (L1 and N) and ground terminals. The upper ground
terminal is for a load cable and the lower ground terminal is for UPSs. The wiring shall be done
according to the wiring diagrams. The terminals and cable routing is shown in Figure 44.
