DANGER
!
• Do not remove the digital operator from the unit since it carries
high voltages and are extremely dangerous.
between operator and unit is also prohibited.
• Do not touch the terminals since some of them carry high voltages
and are extremely dangerous.
Otherwise, it may cause an electric shock.
• Do not remove the cover when power is being supplied to the
inverter. Always turn off the power to the inverter through the
MCCB when detaching the cover.
Otherwise, the capacitor remained charged may be very dangerous.
• After turning off the main circuit power supply, wait for a while
before maintenance or inspection since it may remain charged.
Otherwise, it may cause an electric shock.
• Maintenance, inspection, and replacement of parts must be done
only by authorized personnel.
Otherwise, it may result an injury or an accident.
• Remove all metal objects, such as watches and rings, before the
maintenance, inspection, and replacement of parts. Also, always
use grounded tools.
Otherwise, it may cause an electric shock.
CAUTION
!
• Do not touch the CMOS IC in the control board directly.
Otherwise it can be damaged by static electricity.
• Do not change the wiring, or remove the digital operator or
connectors, during operation.
Otherwise, it may cause a personal injury.

MOSCON-E7 User's Manual
Periodically inspect the MOSCON-E7 within 18 months of shipping
from the factory or within a year of being delivered to the user,
whichever comes first. Regular inspection will prevent accident and
ensure high-performance with higher-reliability.
7.1 Daily inspection
Check the system in operation if:
• the motor vibrates or makes unusual noises.
• there are any abnormal heat generation
• the ambient temperature is too high
• the output current value shown on the monitor display is higher than
normal
• the cooling fan is operating normally.
7.2 Periodic inspection
Refer to the table below for the periodic inspection.
!
• Always turn off the power supply before the inspection.
Otherwise, it may cause an electric shock.
• After turning off the main circuit power supply, wait for a while
before maintenance or inspection since it may remain charged.
Otherwise, it may cause an electric shock.
