1. NOTICE ON SITE SELECTION
This instrument is intended to be used in
the following environment (IEC61010-1)
Overvoltage category II, Pollution degree
2
Mount the controller in a place with:
1) A minimum of dust, and an absence of
corrosive gases
2) No flammable, explosive gases
3) Few mechanical vibrations or shocks
4) No exposure to direct sunlight, an
ambient temperature of 0 to 50°C (

) that does not change rapidly
5) An ambient non-condensing humidity
of 35 to 85%RH
6) No large capacity electromagnetic
switches or cables through which large
current is flowing

2. NOTICE ON THE WIRING
1) The terminal block of KT4, 8 and 9
series are designed to be wired from the
left side. The lead wire must be inserted
from the left side of the terminal, and
fastened by the terminal screw. Use a
solderless terminal with insulation sleeve
that fits to the M3 screw.

that fits to the M3 screw.
2) Terminal fastening torque is approxi-
mately 0.6N·m to 1.0N·m (KT4, 8 & 9).
For KT7 series by M2.6 screw is less than
0.5N·m and by M2.0 screw 0.25N·m
respectively.

For KT7 series by M2.6 screw is less than
0.5N·m and by M2.0 screw 0.25N·m
respectively.
3) Use a thermocouple and compensating
lead wire according to the input
specification of the controller.
4) Use a 3-wire system of RTD according
to the input specification of the controller.
5) This controller has no built-in power
switch, circuit breaker or fuse. Therefore,
it is necessary to install them in the circuit
near the external controller.
(Recommended fuse: Time-lag fuse,
rated voltage 250V AC, rated current 2A)
6) In the case of 24V AC/DC power
supply, do not confuse the polarity when it
is DC.
7) With the relay contact output type, use
an auxiliary electromagnetic switch
externally according to the capacity of the
load to protect the built-in relay contact.
8) When wiring, keep input wire
(thermocouple, RTD, etc.) away from AC
source and load wire to avoid external
interference.
9) Turn the power supply to the instrument
off before wiring or checking. Working or
touching the terminal with the power
switched on may result in Electric Shock
which could cause severe injury or death.
10) Do not drop wire chips into the holes
of vent when wiring, because they could
cause fire, malfunction or trouble with the
device.
11) To prevent the unit from harmful
effects of unexpected high level noise, it is
recommended that a surge absorber be
installed between the electromagnetic
switch coils.

3. NOTICE ON THE MOUNTING
1) Do not use excessive force while
screwing in the mounting bracket of KT4,
8 & 9 series. Recommended torque is
approximately 0.12N·m.
2) When mounting the KT7 series to the
DIN rail, mount it in a lateral direction.
Make sure a click is audible when fixed
into place.
