Safety Instructions

Please read this instruction manual carefully before use to ensure proper operations.
Installation
◦ Do not install this unit in a place with a lot of dust, dirt,
metal pieces, etc.
◦ Use this unit in the operating environment of
temperatures between 5 to 40 °C and humidity of 80%
or less (no dew condensation).
◦ Do not place heavy objects on top of this unit or stack
them.
◦ Choose a stable location with no vibrations. Especially,
when installing this unit in a high place, fix it firmly.
◦ Do not install this unit near high-voltage equipment
or in a noisy environment.
Handling
◦ On any commercial power supply, be sure to install an
earth leakage breaker and a safety breaker.
◦ Connect the earth wire and use this unit with the
specified rated voltage.
◦ The load connected to the output terminal on the
back should not exceed the rated load. Exceeding the
rated load may cause a malfunction.
◦ If external devices connected to the I/O ports on the
back are affected by the electromagnetic induction
load from the relay, solenoid valve coil or others, take
measures against noises by using a diode to absorb
reverse voltage. Otherwise, it may cause a malfunction
and failure.
◦ When the automatic screwdriver is locked or
overloaded, the overload protection works. Please
note that if the overload protection works frequently,
that operation may impose a load larger than the
capability of this unit or the automatic screwdriver.
◦ Even if it is properly used, if the overload protection
works frequently with abnormal events including
heat-up, immediately stop using it, turn off the power,
unplug the power cord, and send it to our service
department for repair.
◦ When you tighten screws of workpieces such as resin
products that are charged with a lot of static
electricity, discharge them before screw tightening. If
the workpieces are not completely discharged, static
electricity may flow into the unit from the tip of the bit
causing malfunctions.
◦ When external equipment is to be used with an
external power supply using the function of this unit,
use the GND as the common terminal.
◦ Failure to do so may cause a malfunction and failure.
◦ Do not apply a voltage to the input side. It may cause
a malfunction.
◦ Do not make the wiring for input / output longer than
necessary.
◦ Note that bundling power cables together may cause
a malfunction.
◦ Do not connect parts other than specified ones to the
connection part of this unit. It may cause a
malfunction.
◦ Do not disassemble or remodel this unit. It may cause
a malfunction.
◦ In that case, we may not be able to accept your claim
for warranty or repair.
◦ Do not cause any strong impacts or vibrations against
this unit.
◦ Do not drag cords and do not allow them to touch oil
or sharp edges, or to be trapped under heavy objects.
◦ When connecting/disconnecting the power cord or
screwdriver cord, always hold the plug.
◦ If it is not used for a long time, turn off the power and
disconnect the power plug from the outlet for safety.
