GENERAL INFORMATION
DEFINITION OF INVERTER
The Mikasa FU162A with built-in high frequency induction
motor, is a special inverter to convert single phase AC 80-
130V and single phase AC180-250V power to the voltage
and frequency suitable for use by a high frequency vibrator.
The output frequency can be varied from 100Hz to 240Hz.
This small and light weight inverter is portable, and it is
suitable for use at every concrete casting site.
COMPONENTS
Electric parts other than the external cooling fan, output
outlet and power cable are placed inside the dust and
water proof box. For protection of the box, a pipe frame
is provided.
The power cable led inside the box is connected to the relay
substrate.Via the relay substrate, the cable is connected to
the circuit protector, then to the voltmeter. The output from
the circuit protector is connected to the output outlet via
the rectifier, smoother, inverter circuit, and control circuit.
POWER TRANSMISSION
This machine converts the commercial power or single-
phase AC power from a generator into direct current. The
direct current is then converted again, by electronic control,
to high frequency AC power suitable for a high frequency
vibrator.
Commercial power (single-phase AC) enters through the
power cable, and when the attached breaker switch is
turned on, electric current flows through the circuit. This
current is converted to direct current via the rectifier and
the condenser.This direct current is converted again by the
transistor switching control to alternate current suitable for
a high frequency vibrator. The power is sent to the output
outlet and the power is supplied to the high frequency
vibrator.
APPLICATION AND TECHNIQUES
A high frequency vibrator can be connected to the inverter.
This machine should only be connected to the specified
high frequency vibrators.
As input power source, use general commercial power
and power generator that is equivalent to the general
commercial power. Do not connect to other power sources.
Also, do not use this machine beyond the allowable input
voltage of the inverter. Otherwise, the vibrator and the
inverter will be damaged.
Do not try to connect to a vibrator having a motor with
different specification by altering the plug and the outlet
for connection. The vibrator and the inverter might get
damaged, and also there is a danger of electric shock.

COMPONENTS
Figure 2 shows the location of the basic controls and
components of the FU162A Inverter. The function of each
control is described below:
1. Guard Frame — Protects the components of the
frequency inverter.
2. Power Cable —Connects the inverter to the power
plug.
3. Power Plug — Connects to the power source.
4. LED — Green LED lamp lights up when at normal
voltage range. If the green or orange LED lamp is
blinking or the red LED is ON, abnormality in power
source is detected. Stop using immediately.
5. Outlet — Connects the vibrator to the inverter.
6. Frequency Adjustment /Abnormality Display
Switch — The display indicates operation frequency,
input voltage, output current, input current in normal
mode. When there is an abnormality, an error number
is indicated.
7. Circuit Protector Switch — Check to make sure that
the switch is always turned off when machine is not in
use. If you insert the power plug into the power outlet
when switch is turned on, the vibrator connected to
the inverter might start suddenly, which might cause
an accident.
8. Voltmeter Input — Indicates the input voltage. Make
sure voltage is in the green zone.

PAGE 14 — FU162A INVERTER • OPERATION MANUAL — REV. #0 (05/12/22)
INSPECTION
BEFORE STARTING
1. Read safety instructions at the beginning of manual.
2. Check power plug and contact for dirt, rust, deformation
and breakage.
3. Check power cable for wear, crushing, crack, etc.
4. Open the output outlet cover to check inside and
terminal part for dirt, etc. Check bolts and nuts used on
inverter for looseness, deformation, etc. Also check the
output outlet cover for smooth open/close movement.
5. Check circuit protector switch to see if it properly
switches ON and OFF, and the green LED turns ON.
After inspection, always turn the switch OFF.
6. Connect to a vibrator and check to see if the vibrator
operates normally.
7. Check anti-vibration rubber for deformation and cracks.
8. Check conduction resistance between power plug
contacts when circuit protector is OFF.
For safety purpose, the input voltmeter needle moves
when the power plug is inserted into the power source
outlet even if the circuit protector is turned OFF.
Measure conduction resistance between power plug
contacts. The tester needle will point to around 200
to 300Ω. This is the impedance (resistance) of the
voltmeter, not conduction trouble.This value pointed by
the tester may vary slightly depending on the detection
method and accuracy of the tester.

OPERATION
1. Check to see if the power source matches the
specification of this inverter and the voltage is within
the normal voltage range of this product. When a
generator is used, check to see if it is of or above the
rated output shown in Table 6.
2. Connect the power plug to the power source, then
check to see if the voltmeter on the inverter shows a
value within the green zone (Table 6). Always connect
the grounding wire. For single phase 100V outlet of
non-grounding type (without grounding wire), use the
grounding clip attached to the power plug to connect

NOTICE
If used at a voltage exceeding values shown in Table 6,
the inverter board and parts may be damaged.
If the voltage used is low, the inverter output gets
lowered and the performance of the concrete vibrator
will also be lowered, making it difficult to do efficient
concrete consolidation. Also, the inverter substrate and
parts might be damaged.
3. Turn on the inverter circuit protector switch (Figure 3).
Make sure that the cooling fan starts and the green LED
lamp lights up (normal voltage range). If the green or
orange LED lamp is blinking or the red LED is lighted,
some abnormality has been detected in the power
source. Stop using immediately and correct the cause
of abnormality before operation.

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 1m2per minute with a water spray nozzle having
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.
