Warning: The UPS system’s output voltage is set at 220/380V by default. If you require output voltage of 230/400V or 240/415V, you must
change the UPS system’s output voltage by accessing the output setup menu described in
Section 10-5-2
. You must place the UPS system in
bypass mode before changing the output voltage. Do not connect your equipment to the UPS system’s output until you have set the proper
parameters.
