An ambient temperature from +20 to +25 °C is recommended to achieve a long
life of the UPS and batteries. The cooling air entering the UPS must not exceed
+40 °C. Avoid high ambient temperature, moisture, and humidity.

4.3.2 UPS system power wiring preparations
Note: If you are installing a maintenance bypass, provide one of the following:
- a minimum of 2 separate feeds with upstream feeder breakers or
- a single feed with 2 upstream feeder breakers: one for the UPS or rectifier
input breaker (if installed) and one for the maintenance bypass input.
Do not use a single feed or a single feeder breaker to supply both
- the UPS or rectifier input breaker and
- the maintenance bypass.
If a bypass input breaker is installed in the maintenance bypass and a single-
feed UPS is being installed, a single feed to the maintenance bypass is
acceptable for supplying both the UPS and the bypass.
When you plan and perform the installation, read and understand the following
