3.6 Installing Cables for Parallel UPSs

NO TICE

● Before parallel running, ensure that all output circuit breakers for each UPS are

ON. Otherwise, a UPS fault (error code #72) will occur.

● Batteries must be connected for parallel running.

Installing AC Input and Output Power Cables

1. Switch off the upstream AC circuit breaker for the UPS.
2. Remove the AC input and output terminal cover from each UPS.
3. Install AC output power cables and then AC input power cables in sequence.

Figure 3-8 AC input, output, and battery wiring diagram (using two UPSs

connected in parallel as an example)

Installing Battery Cables

After lithium batteries are connected in parallel, connect signal cables to the BMS

ports on the UPS. Install a build-out resistor at the COM-OUT port on the last

lithium battery.
