1. The Matters regarding Safety
WARNING
For matters, regarding safety, potential damage to equipment and/or
facilities, additional instructions are indicated by the following headings:
Exercise extreme caution as indicated. This heading indicates hazardous
conditions that could cause injury or death of personnel.
CAUTION
Exercise extreme caution as indicated. This heading indicates hazardous
conditions that could cause damage to equipment and/or facilities.
NOTE
This heading indicates additional instructions and/or notes.
The mark designates a protective conductor terminal. Make sure to
properly ground it.
CAUTION
•Fuse: Since the instrument does not have a built-in fuse, do not
forget to install a fuse in the power circuit to be connected to the
power terminal.
The fuse should be positioned between the switch or the breaker
and the instrument and be attached to the L side of the power
terminal.
Fuse Rating: 250V AC 1.0A/medium lagged or lagged type
Use a fuse which meets the requirements of IEC 127.
•Voltage/current of a load to be connected to the output terminal
and the alarm terminal should be within a rated range. Otherwise,
the temperature will rise and reduce the life of the product and/or
result in problems with the product.
For the rated voltage/current, see 2. Specifications on page 12.
The output terminal should be connected with a device which
meets the requirements of IEC 1010.
•A voltage/current different from that of the input specification
should not be added on the input terminal. It may reduce the life
of the product and/or result in problems with the product.
WARNING
series controller is designed for controlling temperature,
humidity and other physical subjects. It must not be used in any
way that may adversely affect the safety, health or working
conditions of those who come into contact with the effects of its
usage. When used, adequate and effective safety countermeasures
must be provided at all times. No warranty, express or implied, is
valid in the case of using this product without the use of proper
safety countermeasures correspondingly.
CAUTION
To avoid damage to the connected equipment, facilities or the
product itself due to a fault of the product, safety countermeasure
must be taken before usage, such as proper installation of the fuse
and the overheating protection device. No warranty, express or
implied, is valid in the case of usage without having implemented
proper safety countermeasures.
CAUTION
• The mark on the plate affixed to the instrument: On the
terminal nameplate affixed to the case of your instrument, the
mark is printed. This is to warn you of the risk of electrical shock
which may result if the charger is touched while it is energized.
For the rated voltage/current, see 2. Specifications on page 12.
For the rated voltage (mV or V) or current (4~20 mA) input, the
input terminal should be connected with a device which meets the
requirements of IEC1010 as input terminals.
•As the CT input terminal for the heater break alarm (optional),
only the attachment CT should be used. Using anything else may
result in problems with the product.
For the CT provided, refer to 3-1. Check before Use on page 14.
•The CN130 series controller is provided with a draft hole for heat
discharge. Take care to prevent metal or other foreign matter from
obstructing it. Failure to do so may result in problems with the
product and may even result in fire.
•Do not block the draft hole or allow dust or the like to adhere to it.
Any rise in temperature or insulation failure may result in a
shortening of the life of product and/or problems with the product.
For spaces between installed instruments, refer to 4-4. External
Dimensions and Panel Cutout on page 3.
• It should be noted that repeated tolerance tests against voltage,
noise, surge, etc., may lead to deterioration of the instrument.
• Remodeling the instrument or using it in an anomalous way is
prohibited.
• A means to allow the power to be turned off, such as a switch or a
breaker, should be installed in the external power circuit to be
connected to the power terminal of the instrument.
Fix the switch or the breaker adjacently to the instrument in a
position which allows it to be operated with ease, and with an
indication that it is a means of turning the power off. The switch
or the breaker should meet the requirements of IEC 947.
