All cables enter and exit the enclosure via appropriate cable glands. The cable glands must meet a
minimum requirement of IP66 to maintain the integrity of the enclosure. If the ISUPS is to be installed in
a Zone 1 environment, then the gland used on the incoming AC supply will need to be certified to ‘Ex d’
or ‘Ex e’.
NOTE
Cable glands into the ISUPS enclosure must be a minimum of IP66. If
the enclosure is going to be installed in Zone1, then the AC Mains gland
must be rated to ‘Ex d’ or ‘Ex e’.
Typical use of this power supply is for gas detection systems but it is also suitable for voice
communication systems, serial to Ethernet converters, and other electronic equipment requiring
intrinsically safe power in Group I applications. The Intrinsically Safe UPS can be used as a simple
backup system for IS circuits in line with the output parameters and the factory default configuration or
can be user configured with optional functions.
The user can configure various functions of the UPS, as well as the use of the external I/O which
includes 3 digital inputs, 3 relay contacts and Modbus communications.
