INSTRUCTION MANUAL
IMCB02-E5
Before operating this instrument, please carefully read this manual and
fully understand its contents. And always keep it around you to make it
available easily anytime.
•
If failure or error of this instrument could result in a critical
accident of the system, install an external protection circuit to
prevent such an accident.
•
Do not turn on the power supply until all of the wiring is completed.
Otherwise electric shock, fire or malfunction may result.
•
Use this instrument within the scope of its specifications.
Otherwise fire or malfunction may result.
•
Do not use this instrument in the places subject to flammable or
explosive gas.
•
Do not touch high-voltage blocks such as power supply terminals,
etc. Otherwise electric shock may result.
•
Never disassemble, repair or modify the instrument. This may
cause electric shock, fire or malfunction.
•
This is a Class A instrument. In a domestic environment this
instrument may cause radio interference, in which case the user is
required to take adequate measures.
•
This instrument is protected from electric shock by reinforced
insulation. So please arrange reinforced insulation to the wire for
input signal against the wires for instrument power supply, source of
power and loads as far as possible.
•
This instrument is manufactured on the assumption that it is used in
the condition of being mounted on the instrumentation panel.
Therefore, take the necessary measures on the equipment side
mounted with this instrument so that the operator or other personnel
are not accessible to high-voltage blocks in this instrument such as
power supply terminals, etc.
•
Always observe precautions described in this manual. Otherwise
serious injury or accident may result.
•
Conduct all of the wiring in accordance with the local codes and
regulations.
•
Install a protection device such as a fuse, etc. in the power supply,
input or output line, if necessary.
•
Do not allow metal fragments or lead wire scraps to fall inside this
instrument. This may cause electric shock, fire or malfunction.
•
Firmly tighten each terminal screw at the specified torque. Otherwise
electric shock or fire may result.
•
Do not place any obstacle around this instrument in order not to
impede radiation of heat. And do not close ventilation holes.
•
Do not connect wires to unused terminals.
•
Before cleaning the instrument, always turn off the power supply.
•
Remove stains from this instrument using a soft, dry cloth. Do not use
a volatile solvent such as thinner in order to avoid deformation or
discoloration.
•
Do not rub nor strike the display unit of this instrument with a hard
