(1) In order to ensure safety, the switch housing must be connected to a good grounding wire.
(2) When connecting the switch, tighten the wiring to prevent the insulation inside the switch from being burnt out.
(3) For safety, a mechanical interlock is installed on the steel shell of the iron shell switch. When the shell cover is opened, it cannot be closed; after closing, the shell cover cannot be opened.
(4) When installing, first fix the fixing parts, fix the wooden switchboard with the fasteners on the wall or the pole, and fix the iron shell switch on the wooden switchboard.
(5) The iron shell switch should be installed perpendicular to the ground. The installation height is convenient for manual operation, usually around 1.3~1.5m.
(6) The power supply line of the iron shell switch and the output line of the switch must pass through the inlet and outlet holes of the iron shell. When installing the wiring, install a rubber washer at the inlet and outlet holes to prevent dust from falling into the iron shell.
(7) When operating, it must be noted that the iron shell switch must not be opened or closed, and the closing is generally performed with the left hand. If the fuse is replaced, it must be done after the brake is applied.
