5. Installation, Operation, and Maintenance
a) Before installation, check the rated operating current
is consistent with the contract, and check the product for
damage or integrity.
b) The switch should be installed inside the circuit
control switch and fuse. No overload, short circuits or
no-voltage protection is provided for this switch. Its
wiring connection is shown in Fig. 1. Do not install it in
a place whether there is too wet or there is corrosive gas.
c) The switch cannot be used for frequent braking.
d) The metal shell must be grounded.
e) The switch is not suitable for hoisting or lifting
equipment.
f) When the motor is in a forward rotation state, to make
it rotate reversely, turn the handle to the "Stop" position
to stop the motor, and then turn the handle to the
"Reverse" position from the "Forward" position to rotate
it reversely. The stator winding of motor will generate a
very large inverse current due to the sudden reverse
connection of power supply, which easily cause damage
to the motor stator winding due to overheating.
g) Please often check the contact surface and rotating
mechanism during the operation of switch (turn off the
power supply before check); if found that the contact is
burnt or the rotating mechanism works inflexibly, please
timely repair it before use; if the mechanism is rotating
inflexibly, an appropriate amount of grease shall be
applied between the cam rollers.
