Notice
When setting the specifications and functions of this controller, connect terminals 1 and 2 for power
source rst, then set them referring to “5. Setup” and “6. Operation flowchart” before performing
“3. Mounting to the control panel” and“4. Wiring”.
3. Mounting to the control panel
3.1 Site selection
This instrument is intended to be used under the following environmental conditions
(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
• Few mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 )
that does not change rapidly
• An ambient non-condensing humidity of 35 to 85%RH
• No large capacity electromagnetic switches or cables through which large current is flowing
• No water, oil or chemicals or where the vapors of these substances can come into direct
contact with the controller

3.4 Mounting to DIN rail
Caution
Mount the DIN rail horizontally.
When DIN rail is mounted vertically, be sure to use commercially available fastening plates at both ends of
KT7 series. Mount the KT7 series to the DIN rail so that the KT7 series cannot move.
However, if the DIN rail is mounted horizontally in a position susceptible to vibration or shock, the
fastening plates must be used as well.
Recommended fastening plate
Matsushita Electric Works, Ltd. Fastening plate ATA4806
(1) Hook (A) of KT7 series on the upper side of
the DIN rail. (Fig. 3.4-1)
(2) Making (B) part of the KT7 series as a support,
fit the lower part of the KT7 series to the DIN rail.
KT7 series will be completely fixed to DIN rail with
a “Click” sound. (Fig. 3.4-1)
(Fig. 3.4-1)
4. Wiring
Warning
Turn the power supplied to the instrument OFF before wiring or checking it.
Working or touching the terminal with the power switched ON may result in severe injury or
death due to Electric Shock.
