WARNING
 An external protection device must be installed if
failure of this instrument could result in damage to
the instrument, equipment or injury to personnel.
 All wiring must be completed before power is turned
on to prevent electric shock, fire or damage to the
instrument and the equipment.
 This instrument must be used in accordance with the
specifications to prevent fire or damage to the
instrument and the equipment.
 This instrument is not intended for use in locations
subject to flammable or explosive gases.
 Do not touch high-voltage connections such as
power supply terminals, etc. to avoid electric shock.
 When the withstand voltage test or each test is
performed, please contact RKC sales office or the
agent. If you make a mistake in the test method, the
instrument failure may result.
 RKC is not responsible if this instrument is repaired,
modified or disassembled
factory-approved personnel. Malfunction may occur
and warranty is void under these conditions.
High temperature caution:
Do not touch the heat radiation fin while the
power is turned on or just after the power is
turned off as it may be at high temperatures.
If touched, burning may result.
 This product is intended for use with industrial machines,
test and measuring equipment. (It is not designed for use
with medical equipment and nuclear energy plant.)
 This is a Environment A instrument. In a domestic environment,
this instrument may cause radio interference, in which case the
user may be required to take additional measures.

CAUTION
 Be sure to provide an appropriate surge control circuit
respectively for the following:
− If input/output or signal lines within the building are
longer than 30 meters.
− If input/output or signal lines leave the building,
regardless the length.
 This product is manufactured on the assumption that it is
mounted within
connections such as power supply terminals must be
enclosed in the control panel to avoid electric shock to
operating personnel.
 All precautions described in this manual should be taken to
avoid damage to the instrument or equipment.
 All wiring must be in accordance with local codes and
regulations.
 Always use this product at the rated power supply voltage,
load current and power frequency.
 All wiring must be completed before power is turned on to
prevent electric shock, instrument failure, or incorrect
action.
 To prevent instrument damage or failure, protect the power
line and the input/output lines with a protection device such
as fuse, etc.
 If this product is used for phase control, higher harmonic
noise may be generated. Therefore in this case, take such
measures as separating the power line from the
high-voltage line for load drive.
 Prevent metal fragments or lead wire scraps from falling
inside instrument case to avoid electric shock, fire or
malfunction.
 Tighten each terminal screw to the specified torque found
in the manual to avoid electric shock, fire or malfunction.
 For proper operation of this instrument, provide adequate
ventilation for heat dissipation.
 Do not connect wires to unused terminals as this will
interfere with proper operation of the instrument.
 Turn off the power supply before cleaning the instrument.
 Do not use a volatile solvent such as paint thinner to clean
the instrument. Deformation or discoloration may occur.
Use a soft, dry cloth to remove stains from the instrument.
 To avoid damage to the instrument display, do not rub with
an abrasive material or push the front panel with a hard
object.
 This manual assumes that the reader has a fundamental
knowledge of the principles of electricity, process control,
computer technology and communications.
 The figures, diagrams and numeric values used in this
manual are only for explanation purpose.
