Maintenance and inspection
●
For risk of electric shock, please do not directly touch terminals of the controller. Some
of them have high voltage and very dangerous.
●
For risk of electric shock, please do install the housing before power-on; and must
disconnect the power firstly before removing the housing.
●
For risk of electric shock and fire, please confirm that the power source is in the OFF
state or not before wiring.
●
Inspection and maintenance only can be carried out after cut off the main circuit input
power and confirm that the power charge indicator CHARGE completely extinguished.
There is a risk of electric shock as residual power in electrolytic capacitor.
●
Please make designated professional electrical engineering personnel to conduct
inspection and maintenance. Before work, please take off metal object (watch, rings
etc.), and use tools with insulation protection during operation. Otherwise, it may cause
electric shock.
●
For risk of explosion and fire, used battery, circuit printing plate must not be throw into
fire. Otherwise, it may cause explosion.
●
CMOS IC integrated circuit is installed on main control panel. Full attention shall be
paid during operating. The electrostatic induction due to direct touching of finger on
the main control panel may cause damage to the main control panel.
●
For risk of electric shock, please do not conduct wiring and removing terminal when
the equipment is energized.
●
For risk of damage to the equipment, the appropriate parameter settings must be
carried out before running after control panel replacing.
