WARNING – PRESSURIZED ENCLOSURE
This enclosure shall not be opened unless the area is known to be free of flammable
materials or unless all devices within have been de-energized.
Refer to Analyzer instruction manual for purge system instructions.
PURGE GAS IS AIR OR NITROGEN
Power shall not be restored after enclosure has been open until enclosure has been
purged for 5 minutes at a flow rate of 225 L/min or more.
WARNING: The safety of this equipment relies on the provision of proper purging and
pressurizing when used in hazardous locations. It must not be put into use without
“Special Permission” from the inspection authority having jurisdiction.
Overpressure: 0.5 mbar (0.2”wc) min. 2 mbar (0.8”wc) nom, 10 mbar (4”wc) max.
Supply Pressure 4.15 bar (60 psi)min. 5.0 bar (72.5 psi) max.
Max. Leakage Rate: 15 LPM @ 10 mbar overpressure
Protective Gas Flow Requirements 225 Lpm min.
WARNING: When nitrogen is used as purge gas, there may be an asphyxiation hazard.
Special Condition of Use
• Repairs of flameproof joints must be made in accordance with struc-
tural specifications provided by the manufacturer.
• Repairs must not be made on the basis of the values provided in Table
1 or 2 of IEC/EN 60079-1.
• The installer must install appropriate protection from light to ensure
that the resistance to light of the IPS-4, or parts of the IPS-4 is satisfac-
tory.
• The installer must ensure that the installation minimizes the risk from
electrostatic discharge.
