Operational temperature
(1)
(1) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air
temperature 2 cm (0.79 in.) below the unit.
-25…+70 °C (-13…158 °F) —
Storage temperature -40…+70 °C (-40…158 °F) For storage and transportation
Humidity

Altitude 0…6000 m (0…20,000 ft) Approvals apply only up to 2000 m (6562 ft)
Overvoltage category
III IEC 62103, EN 62477-1
II
IEC 62103, EN 62477-1, above 2000 m (6562
ft) altitude
Degree of pollution 2 IEC 62103, EN 62477-1, not conductive
LABS compatibility
The unit does not release any silicone or other LABS-critical substances and is
suitable for use in paint shops.
Attributes Values Notes
Electrical protection Electronically protected against overload, no-load, and short-circuits
Overvoltage protection in buffer mode
32V DC typ
35V DC max
If there is an internal buffer module anomaly, a redundant
circuit limits the max output voltage. Buffering stops and
automatically attempts to restart.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.5 mm (0.14 in.) For example, screws and other small parts
Reverse polarity protection Yes -35V max
Input overvoltage protection Yes 35V max, no harm, or anomaly of the unit
Internal input fuse Not included —
