Precautions - HIOS BLT-AY-61 Operation Manual

■ Precautions

Please read this instruction manual thoroughly before use to ensure proper operation.
● On any commercial power source, install a ground-fault interrupt breaker and safety circuit
breaker.
● Connect the unit to ground and use only the rated voltage.
● Do not exceed the rated loads for the output connections on the rear panel. Exceeding the
rated load will cause the unit to malfunction.
● If the unit may be subjected to inductive loads from a relay or solenoid valve coil in auxiliary
equipment connected to the input/output connections on the rear panel, install a reverse
polarity diode to suppress electrical noise. The unit may malfunction if noise suppression is
not installed.
● The overload protection will be activated when the driver is locked or has become over-
loaded. If the driver is overloaded repeatedly, the maximum ratings of the unit or attached
electric driver may be exceeded. If the driver becomes overloaded during Forward operation
or begins to malfunction due to developing excessive heat, stop the ongoing operation im-
mediately, turn the main power switch off, remove the power cable, and contact our service
department for repairs.
● When tightening screws on work pieces constructed of plastics susceptible to static electric-
ity build-up, tightening should be performed after static electricity has been discharged. If
working on pieces that have not been properly discharged, static electricity may flow up
through the end of the bit, causing malfunctions.
● A common GND should be used if the unit is connected to auxiliary equipment that is pow-
ered separately. The unit may malfunction if a common GND is not used.
● Do not apply voltage to the inputs or outputs. This may cause malfunctions.
● Extending input/output connection cables longer than necessary or bundling power cables
together can cause malfunctions.
● Choose an installation area with no vibrations. If the unit is installed in a high location, en-
sure that it is properly secured.
● Do not install the unit near high voltage equipment or in an electrically noisy environment.
● Do not place heavy items on top of the unit, or stack the units on top of one another.
● Do not install the unit in an area where it may be subjected to dust or metal fragments.
● Do not use the unit with anything other than HIOS drivers as this will cause the unit to mal-
function.
● Do not disassemble or modify the unit in any way, as doing so may cause the unit to mal-
function. Such malfunctions are not covered by the HIOS warranty and repairs to the unit
may be refused.
● The operating environment for the driver should be between 5̊C and 40̊C with relative hu-
midity of 80% or less (there should be no possibility of condensation).
● Do not drop the unit or subject it to mechanical shocks.
● Always hold the plug when inserting or removing power cables or driver cords into or from
sockets.
● Do not drag cords or cables, subject them to oil or to sharp edges, or place them under
heavy objects.
● If the unit will not be used for a long period of time, turn the main power switch OFF and
unplug it from the service outlet.
