◆ Precautions on external wiring gland (pressure tight packing) ◆
For both of non-explosionproof type and explosionproof type, take the following into consideration.
1. The pressure-tight packing must fit the finished cable external diameter.
2. Securely tighten the pressure-tight packing so that there is no gap between the packing and the
cable.
3. If not using a pressure-tight packing, make sure to take necessary measures to prevent moisture and
dust from entering.
CAUTION: 1. After the cable is passed through the rubber packing, crush the screwed
packing of gland. At this time, screw the gland until the cable stop slipping.
2. This cable gland is a cable grand with anchor function. After the step(1), be
sure to screw the clamp with screw: M4 and fix the cable surely.
