Special conditions (ATEX)
WARNING
Danger of explosion
Gases or dusts can be ignited in potentially explosive areas. Read and follow the safety instructions to pre-
vent deflagration or explosions.
Provisions shall be made to prevent the rated voltage from being exceeded by transient disturbances of
more than 119 V.
If the temperatures during rated operation are higher than 70 °C at the feed-in points of cables, lines or
pipes, or higher than 80°C at the wire branching points, then cables must be selected whose temperature
data correspond to the actual measured temperature values.
Observe the permissible ambient temperature during operation in potentially explosive areas. The
permissible ambient temperature range during operation is 0 °C to +50 °C.
The connections of the Control Panel may only be connected or disconnected if the supply voltage has been
switched off or if a non-explosive atmosphere is ensured.
The connectors on the backside of the Control Panel must be protected against mechanical damage with the
attached protective housing or on site by customer installation.
The connectors on the backside must be fully tightened to meet the IP65 rating.
The equipment shall be installed in such a way that the risk of mechanical danger is low.
The equipment shall only be used in an area of not more than pollution degree 2, as defined in IEC 60664-1.
The Control Panel may only be mounted horizontally (see: Mounting).
