6.4 ELECTRICAL INSTALLATION
When connecting cabling to the MEM and RSM (if applicable), always pull the cabling first through
the appropriate housing connector without stretching the cabling.
Remove the numbered connectors from the rear of the MEM to connect all cabling. After connecting
cabling, plug the connectors into the RSM first and then into the rear of the MEM when reinserting
the MEM back into the housing.
6.4.1 ELECTRICAL PRECAUTIONS
Explosion hazard
● A live circuit can cause an explosion. Do not open a powered-up unit when explosive
atmosphere is present.
● For battery powered equipment, never open the housing when explosive atmosphere is
present.
● When installed in a potentially explosive atmosphere that requires apparatus of equipment
protection level Gb and Db, the unit must be installed such that, even in the event of rare
incidents, an ignition source due to impact or friction sparks between the enclosure and
aluminum/steel is excluded.
● Due to internal dissipation, the enclosure temperature can rise above the current ambient
temperature. At the specified maximum ambient temperature of 70 °C / 158 °F, the enclosure
will always remain below the maximum T6 temperature of 85 °C / 185 °F.
● When mounted directly on or near a process, the process temperature shall not exceed the
specified maximum ambient temperature of 70 °C / 158 °F. If this is not possible, a suitable
thermal separator should be used to limit the temperature rise at the outside of the unit, to the
maximum ambient temperature.
● Always use suitable cable and cable glands to withstand the maximum temperature of the
installation. Cable running along a high temperature process, should be suitable for the process
temperature.
Equipment damage
● Electro static discharge can inflict irreparable damage to electronics! Before installing cabling,
always first discharge yourself by touching a well-grounded object.
● Always install the unit according to the EMC guidelines (Electro Magnetic Compatibility) and
according to local requirements (e.g. in Canada, the Canadian Electrical Code, C22.1, Part 1
and in USA, the National Electrical Code, NFPA 70 and ANSI/ISA-RP 12).
● Use an effective shielded cable for sensor input signals and ground its screen either to the
appropriate ground terminal (GND) AND the housing, or to the sensor itself, whichever is
appropriate for the application.
