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 (When installing inside a panel, make particular allowance for heat dissipation. Avoid installation in situations such as above equipment that generates heat.) 5) Locations in which temperature rapidly changes may cause condensation. 6) Locations or atmospheres in which gasoline, thinners, alcohol, or other organic solvents are present, or in which ammonia, sodium hydroxide, or other strong alkaline substances may adhere. 7) Locations susceptible to direct impact or the transmission of vibrations, or where splashing with water is possible. 8) In the proximity of equipment in which large switching surges occur or near high-voltage cables, high-voltage equipment, power lines, power equipment, ham radio transmitters, or equipment containing these or similar devices. 9) An ambient non-condensing humidity of 35 to 85%RH 10) No large capacity electromagnetic switches or cables through which large current is flowing 11) 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, 9, 4H, 4B series are designed to be wired from the left side (KT2 series are designed to be wired from the upper and lower direction). 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. Wirepressed terminal Company name Fork type NICHIFU Co., Ltd. J.S.T. Mfg. Co., Ltd. Round type NICHIFU Co., Ltd. J.S.T. Mfg. Co., Ltd. Part number 1.25Y-3 VD1.25-B3A 0.6 N⋅m, Max. 1.0 N⋅m. 1.25-3 V1.25-3 3.2mm dia. .126inch dia. Max. 5.8mm .228inch Fastening torque 3.2mm .126inch Max. 5.8mm .228inch 2) Terminal fastening torque is approximately 0.6N·m to 1.0N·m (KT4, 8, 9, 4H and 4B). For KT7 series by M3.0 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. 15 KT (AKT2,4,7,8,9,4H,4B) 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, 4H and 4B series. For KT4, 8 and 9 series, recommended torque is approximately 0.12N·m. For KT4H and 4B, recommended torque is approximately 0.05 to 0.06 N·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 (KT4, 7, 8, 9, 4H and 4B series) 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. 4) In three phase installations, ensure that R, S, and T are each connected to a 2-line CT that connects with CT1 ((13)– (14)) and CT2 ((14)–(15)) terminals. CT input terminal 5. Please use rod terminals for the terminal portion of the KT7 series. We recommend terminals made by Phoenix Contact. (1) to (4) are AI0.25–8YE, AI0.34–8TQ, AI0.5–8WH, AI0.75–8GY, AI1.0–8RD, and AI1.5–8BK. (5) to (9) are AI0.25–8YE, AI0.34–8TQ, and AI0.5–8WH. The screw tightening torque for (1) to (4) should be no more than 0.5 N·m and for (5) to (9) it should be no more than 0.25 N·m. Make sure no screw is loose.
