The operational temperature range can be reduced by the battery
specification. The DC-UPS includes some safety features, which reduce
the temperature range for charging. See

(1) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air temperature 2 cm below the unit.
(2) Higher levels are allowed when using a wall mounting bracket (catalog number 1606-XLC).
(3) Shock and vibration are tested in combination with DIN rails according to EN 60715, with a height of 15 mm (0.59 in.) and a thickness of 1.3
mm (0.05 in.). These tests are performed with the power supply in standard mounting orientation.
