6Installation, wiring and precautions

6.1 When installing the junction box, check whether the explosion-proof mark on the junction box nameplate matches the installation environment.

6.2 Open the junction box, use a wrench to unscrew the compression nut of the cable entry device, firmly connect the cable to the terminal post (or terminal) in the junction box, then cover the junction box and tighten the screws at the four corners.

6.3 The grounding screw on the junction box must be reliably grounded with a grounding wire.

When the sealing ring inside the device ages and deteriorates, it should be replaced in a timely manner.

6.5 It is strictly prohibited to open the top cover of the junction box when it is live.

During maintenance, attention should be paid to tightening and introducing the rubber sealing ring into the device to avoid scratches or abrasions.

6.7 After the installation of the incoming (outgoing) line connection is completed, the upper cover should be tightened and the installation screws should be firm.

6.8 The minimum outer diameter of the cable used by the user is φ 14/φ 25.
