」
MAC3 is designed for controlling temperature, humidity, and other physical subjects in general
industrial facilities. It must not be used in any way that may adversely affect safety, health, or
working conditions.
「
「「
「
CAUTION」
」」
」
To avoid damage to the connected equipment, facilities or the product itself due to a fault of
this instrument, safety countermeasures must be taken before usage, such as proper installation
of the fuse and the overheating protection device. No warranty, expressed or implied, is valid in
the case of usage without having implemented proper safety countermeasures.

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.
The external power circuit connected to the power terminal of this instrument must have a
means of turning off the power, such as a switch or breaker. Install the switch or breaker
adjacent 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 off the power. Use a switch or breaker, which
meets the requirements of IEC127.
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 breaker and the instrument and should be attached to the L side of
the power terminal.
Fuse Rating: 250V AC 0.5A/medium lagged or lagged type.
Use a fuse which meets the requirements of IEC127
Load voltage/current to be connected to the output terminal and the alarm terminal should
be within the rated range. Otherwise, the temperature will rise and shorten the life of the
product and/or result in problems with the product.
Voltage/current that differs from input specification should not be connected to the input
terminal. It may shorten the life of the product and/or result in problems with the product.
Input, output of voltage pulse, and output of electric current are not insulated. Therefore, do
not ground an adjusted power terminal when a ground sensor is employed.
A signal wire's common mode voltage to ground (signal wires other than contact output
including power supply and event) should be less than 30V rms, 42.4V peak, and 60 VDC .
「
「「
「
CAUTION」
」」
」
All the wires for the interior distribution, except for communication and contact output (including
power supply and event), should be less than 30m in length. When the wire's length is 30m or more,
or in the case of outdoor wiring, the suitable measure against a lightning surge is required.
EMC standard (IEC61326) classifies MAC3 into Class A apparatus. Electromagnetic interference
may occur when MAC3 is used at a business district or in the home. Please use after taking
sufficient measures.
