National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Relevant for use in explosion hazard areas (Hazardous
Locations, Class I, Division 2)
This equipment is exclusively suitable for use in Class I, Division 2,
Groups A, B, C, and D or non-hazardous locations.
This device is an open-type device that is to be installed in an enclosure
suitable for the environment and accessible exclusively with the use of a
tool.
Exclusively use the device for the application cases specified by the
manufacturer. Failure to follow these instructions can impair device
protection.

characteristic value P
All of the following requirements are complied with:
There are fuses suitable for DC voltage in the positive conductors of
the supply lines, or the voltage sources are appropriately current-
limited. Regarding the properties of this fuse: See “Technical data”
on page 65.
The power sources are electrically isolated from the ground
potential. According to specification IEEE 802.3, the insulation
voltage must be 1500 V AC or 2250 V DC.
