2. Connect input L2 wire to UPS input L2 terminal.
3. Connect input GND wire to input GND terminal.
4. Connect output L1 wire to UPS output L1 terminal.
5. Connect output L2 wire to UPS output L2 terminal.
6. Connect output N wire to UPS N terminal.
7. Ensure ISO TAP Jumper is in correct posion (208V for 208V input or 240V for any other input
voltages).
8. Ensure Output voltage parameter is set to match the site input voltage. Refer to secon 3.3
NOTE 1: The ISO Tap Selector Jumper is electrically located between the output of the inverter and the
transformer primary. In the 208V posion it steps up the voltage by 11%. In the 240v posion there is
no voltage change. 208V is default Posion. Refer to gure 2-4.

NOTE 1: If other than default seng is desired, conguraon can be done at the factory for an
addional voltage conguraon fee.
6. Aer connecng the wires, replace the terminal block cover on the rear panel of the UPS.
NOTE 1: Install the output breaker between the output terminal and the Load. I.A.W NEC code.
NOTE 2: UPS Cabinet contains an Isolaon Transformer with N-G bond. This system qualies as a
separately derived source.
Warning:
Make sure the UPS is turned o before installaon.
The UPS should not be turned on during wiring connecon.
