    Control Box

    The explosion rated box is fitted with a single output gland for the control cable. The box is fitted with a unit “Ready Lamp” showing the unit has power and is available. A “Start” button switches the output of the unit “On” and a “Power On” lamp illuminates when the power is On. A “Stop” button switches the output off and the “Power Off” lamp extinguishes.

    The box is be fitted with an “Emergency Stop” mushroom which when pushed will locks and stop the unit from functioning. The “Ready Lamp” then extinguishes.

    All Glands, Lamps and Buttons are explosion rated.

    Junction Box

    The explosion rated box is fitted with 2 input glands for the 2 x 400mm2 cables and 4 output gland for the 4 x 70mm2 cables.

    All Glands are explosion rated.
