INSTALLATION INSTRUCTIONS - (
II 2 G Ex e IIC Gb Ta -15°C to +120°C)
Determine location for the hub mounting hole, making sure there is enough room internally to install the locking nut. Using the dimensions in the table
below, machine a mounting hole in the enclosure, following the maximum wall thickness dimensions. Secure the locking nut to the hub body using the
torque values below. Tighten the locking ring set screw. Install Ground [Earth] Lead, consisting of a maximum of TWO 6-AWG TO 14-AWG solid or
stranded copper wires, between the ground bracket and the lock nut and tighten the ground screw to the specified torque. If the available Ground
[Earth] Lead AWG is greater than specified, a copper lug style connector, specified per NEC may be utilized. Reference NEC for Ground [Earth] Lead
preparation and insulation stripping requirements. Both screws should be tightened to 35 lb/in (4.0 Nm). Hub is now ready to accept NPT threaded
conduit or cable fittings (glands).
