New Multiple Parallel UPS Installation

Only qualified service personnel (such as a licensed electrician) shall perform the electrical installation. Risk
of electrical shock.
NOTE Do not make unauthorized changes to the UPSs; otherwise, damage may occur to your equipment
and void your warranty.
To install two to six UPSs in a new parallel configuration:
1. Verify that the UPSs to be paralleled are installed in individual rail kits in a rack
containing a BladeUPS Bar.
2. Switch off utility power to the distribution point where the parallel system will be
connected. Be absolutely sure there is no power.
3. Verify that all circuit breakers are in the OFF (O) position.
NOTE The load connector breaker controls the load connector only, not the output power cord.
4. Unpack the Powerware Hot Sync CAN Bridge Card and verify that the card was
not damaged during shipment (see Figure 33).
NOTE Eaton recommends installing the Powerware Hot Sync CAN Bridge Card in X-Slot Communication
Bay 2 (see Figure 32 on page 43), leaving Communication Bay 1 available for other types of X-Slot cards.
5. Remove the X-Slot communication bay cover on the UPS and retain the screws.
