13. Safety rules of electrical
system
1. ONLY can the personnel who is trained or has
professional knowledge do electrical repairing and
maintenance .
2. DON'T modify or omit the safety interlocking devices.
3. Reading the warning signs before operation.
4. Turning off the power and locking the main switch before
eliminating the trouble.
5. If the air is too moist, watching out for getting an electric
shock.
6. The room should be cleared, before the lift got power.
7. The control box can be opened ONLY when the
electrical inspection need to be carried out.
8. Without the authorization of manufacturer, CAN'T modify
the circuit.
9. Confirming that the electrical accessories are in
accordance with the specifications (including the colour
code of wires), before changing them.
10. DON'T wear glasses with metal frame, necklace, ring,
watch or bangle during the operation.
Notice for onsite installation
and adjustment of electrical
equipment
1. The external power cord must be copper core which
can't be under 4 mm
aluminum core. Some external power cords were
found on site only 1.5mm
current of 10A. Comparing to the operating current of
15.9 A when the lift is fully loaded, this severely
contravenes the requirements. Personnel for
installation and adjustment must clarify this to
customer.
2. The external power cord (4 mm
be longer than 10m , which means the length from

main switch to power unit can't be above 10m, if
above ,the installation personnel should require
customer to provide power cable with larger diameter.
3. Power cord and air switch must connect correctly
and firmly. It's found on site that when lift was being
used by customer ,the lock screw of air switch had
slipped and didn't lock the power cords at all ,which
led to the continuous power's on-and-off and result in
the breakdown of power unit. If the air switch can't be
locked, the installation and adjustment personnel must
inform customer that a sound air switch must be
provided.
4. The power cords of lift must be separated from
home appliance and the air switch for lift power wire
can't be shared using by home appliance. For the
reason that the use of home appliance would cause
voltage drop, with the inadequate voltage the current
will increase and can easily make the motor coil burn
out.
5. During installation and adjustment, the button box
would be opened to put in the power wire and signal
wire. As a must, these wires should be ordered and
clear to avoid interference with the use of other
electrical equipment. Also the wire connection must be
firm.
6. The power wire of lift can not be directly inserted in
wire board with plug. It must connect with air switch.
The wire of wire board for civil use is normally very thin
and some of which are only 1.5 mm
the current of lift, and would also cause severe voltage
drop to burn out the motor.
