 NOTICE ON OPERATION
 
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 (
32 to 
122°F
) 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
7) No water, oil or chemicals or where the 
vapors of these substances can come into 
direct contact with the controller
 
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.
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.
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.
 
4. OPTIONAL HEATER BURN-OUT 
ALARM OUTPUT
 
1) This alarm is not available for detecting 
current under phase control.
2) Use the current transformer (CT) 
provided, and pass one lead wire of the 
heater circuit into the hole of CT.
3) When wiring, keep CT wire away from 
AC source and load wire to avoid external 
interference.
