ŶInstallation Area
ƔUse a HIOS power supply that is compatible with the driver being used.
ƔInstall the unit in a temperature and humidity controlled room with adequate ventilation.
ƔInstall the unit in an area that is not subjected to dust, dirt or metal fragments.
ƔInstall the unit in an area that is not subjected to water or oil.
ƔDo not place heavy items on top of the unit or stack units on top of one another.
ƔSelect a safe installation area that is free from vibrations.
ƔIf the unit is to be installed in an elevated location, ensure that it is fixed firmly so that there is no
danger of the unit falling.
ƔDo not install the unit near other high-voltage equipment or electronically noisy environments.
ƔDo not use input and output cables that are longer than required or knot them. Doing so may
result in incorrect readings.
ŶPrecautions for Use
ƔGround the HIOS power supply connected to the unit and use the power supply within the
specified rated power and voltage.
ƔEnsure that loads connected to the output terminals on the rear panel terminal block do not
exceed the rated load.
Exceeding the rated load can cause a malfunction.
ƔIf external equipment connected to the +DC 24 V output terminal or input/output terminals on the
rear panel terminal block are affected by the electromagnetic induction of relays and solenoid
valves coils, noise prevention in the form of reverse voltage absorbing diodes should be used.
Equipment may operate incorrectly or malfunction if noise prevention is not used.
ƔDo not connect the +24 V DC terminals on the rear panel terminal block to the GND terminal.
Doing so will result in a malfunction.
ƔDo not connect the +24 V DC terminals on the rear panel terminal block to any output terminal.
Doing so will result in a malfunction.
ƔA common GND terminal should be used if the unit’s functions are used to power external
equipment with an external power supply. Equipment may operate incorrectly or malfunction if a
common GND is not used.
ƔDo not provide additional voltage to the input terminals. Do not provide voltage or current to the
output terminals that exceeds their rated values. Doing so can result in a malfunction.
ƔUse the unit in temperatures of 5°C to 40°C and 80% or less humidity (with no condensation).
ƔAlways hold the plug when connecting or removing the power cord or driver cord.
ƔDo not pull the cords, drag them across oil or sharp edges, or place heavy objects on top of them.
Doing so may result in severed wires or malfunctions.
ƔThe overload protection function of the HIOS power supply connected to the unit will operate if the
driver remains locked or becomes overloaded. Please note that work involving repeated
overloads will increase load over the capacity of the connected HIOS power supply and electronic
driver. If the unit malfunctions with repeated overloads during normal operations, immediately stop
using the unit, turn off the main power switch of the HIOS power supply connected to the unit,
remove the power cord from the power outlet and bring the unit to our service department.
ƔIf the unit overheats, turn off the main power switch of the connected HIOS power supply, remove
the power cord from the power outlet and let the unit cool down. The unit may be used again once
it has cooled down. If it overheats again immediately stop using the unit, turn off the main power
switch, remove the power cord from the power outlet and bring the unit to our service department.
ƔWhen tightening screws on plastic work pieces that may have a lot of static electricity buildup,
