PH 9283 - PH 9284 .
Note 1: Make sure that the wires are connected tightly with the terminals.
Note 2: There are two kinds of outputs: output terminal/outlets and programmable terminal. Please
connect non-critical devices to the programmable terminal and critical devices to the output
terminal/outlets. During power failure, you may extend the backup time to critical devices by setting
shorter backup time for non-critical devices.
Note 3: Please install the output breaker between the output terminal and the load, and the breaker
should be qualified with leakage current protective function if necessary.
Step 5.
Put the terminal block cover back to the rear panel of the UPS.
2.3. Setup the UPS for a Parallel System
If the UPS is only available for single operation, you may skip this section to the next.
Step 1.
Install and wire the UPSs according to the section 2.2.
Step 2.
Connect the output wires of each UPS to an output breaker.

breaker will directly connect to the loads.
Step 4.
Either common battery packs or independent battery packs for each UPS are allowed.
Step 5.
