Precautions
During
maintenance
•
Do not repair or maintain the controller at power-on. Failure
to comply will result in electric shock.
•
Repair or maintain the controller when its voltage is lower
than 36 VAC, about 10 minutes after the controller is
powered off. Otherwise, the residual voltage in the capacitor
may result in personal injury.
•
Do not allow unqualied personnel to repair or maintain the
controller. Failure to comply will result in personal injury or
damage to the controller.
•
Repair or maintenance of the controller can be performed
only by the warranty center or qualied personnel authorized
by Monarch. Failure to comply will result in personal injury or
damage to the controller.
•
Power supply must be cut off before repair or maintenance
of the controller.
•
Set the parameters again after the controller is replaced. All
the pluggable components must be plugged or removed only
after power-off.
•
Strictly obey the laws and regulations and repair and
maintain the elevator equipment periodically. Only timely
troubleshooting can ensure the safety of passengers.
Disposal
The packaging materials, screws and terminal blocks can be
re-used and it is suggested that you keep them well for future
use.
The electrolytic capacitors on the main circuits and PCB may
explode when they are burnt. Poisonous gas is generated when
the plastic parts are burnt. Treat them as ordinary industrial
waste.
1.2 General Precautions
1. Requirement on the residual current device (RCD)
The controller generates high leakage current during running, which flows through the
protective earthing conductor. Thus install a type- B RCD at primary side of the power
supply. When selecting the RCD, you should consider the transient and steady-state leakage
current to ground that may be generated at startup and during running of the controller. You
can select a specialized RCD with the function of suppressing high harmonics or a general-
purpose RCD with relatively large residual current.
2. High leakage current warning
The controller generates high leakage current during running, which flows through the
protective earthing conductor. Earth connection must be done before connection of power
supply. Earthing shall comply with local regulations and related IEC standards.
