UB-Series
24V, 20A, DC-UPS
16. ENVIRONMENT
Operational temperature
*) -40°C to +70°C (-40°F to 158°F) Reduce continuous output current according
Fig. 16-1.
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 chapter 5 for details.
Derating 2.5%/°C +60°C to +70°C (140°F to 158°F)
Storage temperature -40 to +70°C (-40°F to 158°F) For storage and transportation

LABS compatibility The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.
*) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air temperature 2cm below the
unit.
**) Do not energize while condensation is present
***) Higher levels are allowed when using the wall mounting bracket ZM2.WALL
