! WARNING
 To prevent injury to persons, damage to the instrument and equipment,
a suitable external protection device shall be required.
 All wiring must be completed before power is turned on to prevent
electric shock, fire or damage to the instrument and equipment.
 This instrument must be used in accordance with the specifications to
prevent fire or damage to the instrument and 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.
 RKC is not responsible if this instrument is repaired, modified or
disassembled by other than factory-approved personnel. Malfunction may
occur and warranty is void under these conditions.
CAUTION
 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 Class A instrument. In a domestic environment, this instrument may cause
radio interference, in which case the user may be required to take additional measures.
 This instrument is protected from electric shock by reinforced insulation. Provide
reinforced insulation between the wire for the input signal and the wires for instrument
power supply, source of power and loads.
 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.

To prevent electric shock or instrument failure, always turn off the power
before mounting or removing the instrument.
1.1 Mounting Cautions
(1) This instrument is intended to be used under the following environmental conditions.
(IEC61010-1) [OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]
(2) Use this instrument within the following environment conditions:
 Allowable ambient temperature:
 Allowable ambient humidity:
 Installation environment conditions: Indoor use
(3) Avoid the following conditions when selecting the mounting location:
 Rapid changes in ambient temperature which may cause condensation.
 Corrosive or inflammable gases.
 Direct vibration or shock to the mainframe.
 Water, oil, chemicals, vapor or steam splashes.
 Excessive dust, salt or iron particles.
 Excessive induction noise, static electricity, magnetic fields or noise.
 Direct air flow from an air conditioner.
 Exposure to direct sunlight.
 Excessive heat accumulation.
(4) Mount this instrument in the panel considering the following conditions:
 Ensure at least 50 mm space on top and bottom of the instrument for maintenance and
operating environment.
 Do not mount this instrument directly above equipment that generates large amount of heat
(heaters, transformers, semi-conductor functional devices, large-wattage resistors).
 If the ambient temperature rises above 55 C, cool this instrument with a forced air fan, cooler,
etc. Cooled air should not blow directly on this instrument.
 In order to improve safety and the immunity to withstand noise, mount this instrument as far
away as possible from high voltage equipment, power lines, and rotating machinery.
High voltage equipment: Do not mount within the same panel.
Power lines: Separate at least 200 mm.
Rotating machinery: Separate as far as possible.
 For correct functioning mount this instrument in a horizontal position.
(5) In case this instrument is connected to a supply by means of a permanent
connection, a switch or circuit-breaker shall be included in the installation. This shall
be in close proximity to the equipment and within easy reach of the operator. It shall
be marked as the disconnecting device for the equipment.

 For thermocouple input, use the appropriate compensation wire.
 For RTD input, use low resistance lead wire with no difference in resistance between
NO: Normally open
the three lead wires.
 To avoid noise induction, keep input signal wire away from instrument power line, load
lines and power lines of other electric equipment.
 If there is electrical noise in the vicinity of the instrument that could affect operation,
use a noise filter.


The Loader port is only for parameter setup. Not used for data logging
during operation.
 To use the loader communication, power on RZ100/400.
Loader communication can be used on a RZ100/400 even when the
Communication function (optional) is not installed.
The loader communication corresponds to the RKC communication protocol
"Based on ANSI X3.28-1976 subcategories 2.5 and A4."
