3.2 Opening and Closing the Enclosure
Important Ensure that NO TOOLS come into contact with the flamepath
of the enclosure, as this may cause irreparable damage and
render the unit unsafe.
Warning! The iRFID101 flameproof enclosure must NOT be opened when
an explosive gas or dust atmosphere is present, or when the
equipment is energized.
Warning! The iRFID101 flameproof enclosure lid must be secured only
with the bolts supplied, and these must be tightened to the
correct torque value. Contact Extronics for spare bolts.
Important Always re-apply a thin layer of Loctite 8104 or Loxeal GS9
silicone grease to the enclosure flame paths whenever the
iRFID101 flameproof enclosure is opened. This is required to
maintain the IP rating of the enclosure.
3.2.1 Opening the Enclosure (Aluminium and Stainless-Steel enclosures)
The flame paths of the iRFID101 enclosure are supplied with grease applied to protect
them. This can make the enclosure lid difficult to open as the grease can cause it to stick.
Therefore, Extronics recommend the use of a double suction lifter. This tool is included
with iRFID101 deliveries and is available from Extronics or hardware and builders supply
stores. Extronics recommend using a lifter that has a working load of 50kg minimum and
approximate dimensions 300mm x 120mm
• Remove all bolts, using a wrench with an 8mm hex head. Store the bolts carefully
to avoid damage or loss.
• Attach the suction lifter as per the instructions provided and release the door.
