General Guide to Cable Entry Positions into Cable Gland or Enclosure Side:
a.Maximum hole diameter is major thread diameter of cable gland plus 0.7mm (.03”)
b. Minimum material to be maintained between holes:
Glands M16 through M32: 15mm (0.59”)
Glands M35 through M75: 20mm (0.79”)
Glands M75 through M100: 35mm (1.38”)
Prior to making holes in the enclosure wall or gland plate, verify that the selected gland will not have
interference with the sealing washer and lock nut.
c. Hole location must be located so sealing washer and locknut do not interfere with gasket.
d. Select a gland for the correct application with the proper certifications. Make certain all cable gland
accessories are included for through hole installation. Additional accessories may include locknut and sealing
washers.
e. Install the gland in accordance to the manufacturers instructions.
Painted Enclosures require these additional instructions:
7.
For fixed installations minimize the risk of electrostatic discharge of painted enclosures
a. Remove the explosive atmosphere prior to contact or cleaning
b. Make certain enclosure is grounded and external enclosure ground connection is made; all conducting parts
should be properly bonded.
c. For painted surfaces, avoid friction with surface, only clean with wet cloth moistened with de-ionized water.
d. Avoid contact in low relative humidity environments. Increase environment humidity where possible.
