Ambient conditions
Enclosure:
IP 54 pursuant to DIN EN 60529 with standard
socket pursuant to DIN EN 175301-803,
IP 00 with AMP plug.
Safety class: 1.
This unit is not suitable for cleaning with a high-
pressure cleaner and/or cleaning products.
Maximum medium and ambient temperatures:
DG..C: -20 to +70°C (-4 to +158°F),
DG..CT: -15 to +60°C (5 to 140°F).
Long-term use in the upper ambient temperature
range accelerates the ageing of the elastomer ma-
terials and reduces the service life (please contact
manufacturer).
Transport temperature = ambient temperature.
Storage temperature: -20 to +40°C (-4 to +104°F).
