3. Installation in an explosion hazard area 3.1 General The EE300Ex has been certified in accordance with the ATEX 94/9EC Directive, IECEX Scheme, , National Electrical Code (ANSI-NFPA 70 (NEC©) and Canadian Electrical Code (CSA C22.1). Devices in explosion-hazard areas are only permitted for operation in atmospheric conditions ≤ T ≤ 40 °C (104 °F) -20 °C (-4°F) 0.8 bar (12 psi) ≤ p ≤ 1.
3.2 Housing assembly The EE300Ex housing has a two-part construction. • Lower housing section with the connection and earthing terminals. • Upper housing section with the electronics and measurement probe. Upper housing part Lower housing part 3.2.1 Drilling plan for the housing 167 (6.6") 4.5 (0.18") 70 (2.8") The lower housing section is mounted using 4 screws. Screw diameter < 4.5mm (0.18") If the upper housing section is removed from the hazard area, e.g.
3.3 Assembly in category 1 (zone 0 / 20); Division 1 Only intrinsically safe power supply devices are approved to supply EE300Ex in category 1 or Division 1. In areas belonging to gas group IIC or Class I, Division 1, Group A,B, it must be ensured that during installation and operation, the possibility of impact and friction sparks has been excluded in rarely occurring fault situations. Work on open transmitter must only be performed if it is guaranteed that no explosive atmosphere is present.
3.4 Assembly in categories 2 and 3 (Zone 1 2 / 21 22), Division 2 Only intrinsically safe power supply devices and protective barriers are approved to supply EE300Ex in category 2 and 3 or Division 2. No display is permitted in the dust hazard area (Group III) or Class II, III. CH1 and CH2 must be galvanically isolated from one another during operation. The probe for wall mounting is not permitted to be used for Zone or Division bushing.
3.5 Mounting the measurement sensor To mount the transmitter, select a location with stable conditions, i.e. protected against direct sunlight or rain. The measurement probe should be fitted at a location where representative measured values are to be anticipated for the process. Wand / Wall r > 30mm The measurement probe must be mounted horizontally or vertically (downwards). If possible, a drip tray should be placed into position before every installation.
Installation instructions: • Tighten the union nuts finger-tight. • Mark the union nuts at the 6 o' clock position. • Hold the screw connection body tight and tighten the union nuts with 1 ¼ turns to the 9 'o clock position. Assembly with high pressure applications and applications with a high security factor: • Tighten the union nuts until the pipe can no longer be turned by hand or can no longer be moved axially in the fitting. • Mark the union nuts at the 6 o' clock position.
3.5.3 Mounting the probe using ball valve (optional) With ball valve mounting, the system being measured does not need to be emptied or brought to a standstill to mount or remove the probe. Install the sensor head against the flow direction. Metal sealing ring Metal sealing ring It is only permitted to use one ball valve that is approved for use in explosion hazard areas. (included with the ball valve set as standard) (as standard with probe) The process pressure must be below 10bar (145psi).

The configurator software and the drivers are available for download free of charge from our website http://www.epluse.com/en/service-support/download-center/. The EE300Ex in combination with the configurator software is only permitted for use outside the hazard area.
4.5 Grounding and potential equalization The EE300Ex must be integrated into the potential equalization to avoid hazards from electrostatic charges. It shall apply the requirements of the standards EN60079-14, EN60079-25 or IEC60079-14, IEC60079-25. With a remote sensing probe, the probe should also be integrated with the screw connection with a maximum of 1 MΩ in the potential equalization. The ground conductor or the potential equalization connection must have a cross-section of 4mm² (0.
