The configuration or adjustment of EE300Ex may not be performed in the hazard area.
CH1 and CH2 must be disconnected while using the configuration adapter.
When the front section has been removed from the hazard area, e.g. for calibration, the empty bottom
section shall be protected against dirt and electrostatic charge with the blind front cover HA011401 (see
accessories).
4.8 Calibration of the Current Loop
For the calibration of the current loop in explosion hazard areas only approved multimeters are permit-
ted. During the measurement with these multimeters the requirements of the system description (the
proof of intrinsic safety) shall be observed
5 Display (optional)
Display is not permitted in the gas hazard area for EPL Ga IIC or Class I, Division 1,
Group A, B and in the dust hazard area for IIIA, IIIB and IIIC or Class II, III.
For EX6 (TIIS) no display in Ga.
The display shows the measured parameter on the outputs CH1 (top row) and CH2 (bottom row),
according the ordering code.
The top key change the visualization of the calculated parameter on the top row. The bottom key
change the visualization of the calculated parameter on the bottom row. Changing the display
visualization do not change the parameter on the output CH1 and CH2.
6 Maintenance
It is essential that operation and maintenance in explosion hazard areas are only performed by trained
specialist personnel authorised to do so by the system operator.
Maintenance and repair work in explosion hazard areas must comply with the requirements of
EN 60079-17 or IEC 60079-17, EN 60079-19 or IE C60079-19 and with all the relevant national
regulations.
In the U.S. maintenance and inspection must comply with ANSI / ISA RP12.6.01-2003 and the NEC
requirements.
In Canada maintenance and inspection must comply with the CEC requirements.
