Maintenance - MULTIQUIP Mikasa Series Operation Manual

Check the following items before and after use.
1. Check power plug and contact for dirt, rust, deformation
and breakage.
2. Check power cable for wear, crushing, crack, etc.
3. Open the output outlet cover to check inside for dirt.
4. Check terminal part for dirt.
5. Check bolts and nuts used on inverter for looseness
or deformation. Also check the output outlet cover for
smooth open/close movement.
6. Check circuit protector switch to see if it properly
switches ON and OFF, and that the green LED turns
ON. After inspection, always turn the switch to OFF.
7. Connect to a vibrator and check to see if the vibrator
operates normally.
8. Check anti-vibration rubber for deformation and crack.
While doing concrete consolidation, promptly remove the
concrete that splashes on the inverter. When washing the
inverter with water, pay attention to the following point. Do
not wash with water if there is deformation or breakage on
the inverter, or when the female panel outlet cover does
not close securely.
1. Check the bolts, screws, switches and input cable of
the inverter for looseness.
2. Check the parts of the inverter (front panel, switch
panel, top surface cover, side surface cover) for
deformation and crack. If there is deformation or
breakage, dust and water proofing performance will be
lowered, and water might enter inside during washing
with water, leading to trouble of electronic parts.

3. Check the output side outlet cover to make sure it
closes. if it does not close properly, water might enter
inside through the terminal part. When washing, close
the output side outlet.
4. When washing, keep the inverter in the upright position
while splashing water from the top. If washed with the
inverter set on its side or put upside down, the cooling
fan will be immersed in water, leading to malfunction of
the fan. Do not put water nozzle directly to the intake/
exhaust holes at the bottom.
5. Pay attention to the amount and pressure of the water
used for washing to maintain them at the level specified
by JIS standard IP56. See Notice.
NOTICE
The first number "5 (IP5X)" indicates class 5 of dust
proof structure protection class (no effect on machine
when exposed in talc dust for 8 hours), and the ending
number "6 (IPX6)" indicates class 6 of water proof
performance protection class (no abnormality in the
machine when the machine body installed normally is
injected with water from outside from every direction for
more than 3 minutes at a rate of 100 liter per surface
area of 1m per minute with a water spray nozzle having
2
a diameter of 12.5 mm positioned 2.5 to 3.0 m away
from the machine body).
CAUTION
After washing, wipe off the water and let the inverter dry.
Wipe off water also from the inside of the output side
outlet cover and the terminal holes. If there is remaining
water, electric shock and electric leak might occur.
