KONE Elevator Power Board KM713140G04 – Installation, Commissioning & Replacement Guide

The KM713140G04 is the 400 VAC, 6 kW switch-mode power board that feeds every KONE MiniSpace® and MonoSpace® elevator from 630 kg to 1,600 kg. Mounted in the controller cabinet, this board converts 3-phase mains into rock-solid 24 Vdc logic supply, 110 Vdc brake and 230 Vac auxiliary while meeting IE3 efficiency and SIL-2 safety standards. A single shorted IGBT or a swollen DC-bus capacitor will throw a “65” fault and shut the car down. Nanjing Zhuye Elevator Parts keeps hundreds of factory-tested KM713140G04 boards in Rotterdam and Nanjing so you can restore full power the same day. Below is an 800-word field manual that explains correct usage, on-site commissioning and the replacement cycle that keeps your elevators energized, efficient and code-compliant.
1. What the KM713140G04 does
-
6 kW continuous, 10 kW peak, 98 % efficiency at 400 VAC ±10 %
-
24 Vdc logic, 5 A; 110 Vdc brake, 3 A; 230 Vac auxiliary, 2 A
-
Integrated PFC choke, brake chopper and 3 % harmonic filter
-
Dual CAN channels (Power-CAN & Car-CAN) for real-time diagnostics
-
IP20 steel housing, built-in heat-sink, forced-cooling fan 24 Vdc 0.4 A
-
UL/CE certified to EN 81-20/50 and CSA B44.1 for 15-year design life
2. Tools to carry
-
KM713140G04 power board (Nanjing Zhuye part #KN-PWR-KM713140G04-6kW) in anti-static box
-
4 mm, 5 mm, 6 mm Allen keys, 10 mm & 13 mm sockets
-
Torque wrench (10–50 N·m) and 1,000 Vdc multimeter
-
KONE E-Link Service Tool (EEST) laptop with power board plug-in licence
-
IR thermometer and vibration pen
-
Lock-out / tag-out kit
3. Installation – 60 minutes with two technicians
Safety: place the car on top-of-travel buffers, open the main disconnect and wait 5 min for DC bus to discharge (<50 V).
-
Photograph every power and signal connector – note L1/L2/L3, DC+, DC-, 24 V, 110 V, 230 V, CAN.
-
Remove four M6 flange bolts; slide the old board out of the card guides.
-
Check the heat-sink pad – if torn, replace with new 0.5 mm thermal sheet supplied.
-
Mount new KM713140G04; torque bolts to 25 N·m.
-
Re-connect all plugs; apply KONE-supplied conductive grease on DC bus.
-
Power up – STATUS LED blinks green 3 times then solid; CAN LED flashes every 100 ms.
-
Launch EEST → Power → Auto-Tune; board measures PFC inductance and stores values.
-
Run 3 full-speed cycles; verify 24 Vdc ripple <100 mV and heat-sink <70 °C.
-
Record serial number, date and voltage values in CMMS.
4. Functional test – prove it to the controller
a) Output voltages: 24 Vdc ±1 %, 110 Vdc ±2 %, 230 Vac ±3 %.
b) DC bus ripple: <100 mV at full load.
c) Efficiency: >98 % at 50 % load.
d) Temperature rise: <40 K above ambient after 30 min run.
e) Export EEST report and attach PDF to site file.
b) DC bus ripple: <100 mV at full load.
c) Efficiency: >98 % at 50 % load.
d) Temperature rise: <40 K above ambient after 30 min run.
e) Export EEST report and attach PDF to site file.
5. Preventive maintenance schedule
-
Monthly – visual sweep for dust, fan noise or swollen capacitors.
-
Quarterly – measure heat-sink temperature <70 °C with IR gun.
-
Annually – scope PWM outputs; shoot-through spikes must be <50 V.
-
Every two years – replace the 470 µF, 450 V capacitor – ESR doubles every 5 years.
6. Replacement cycle – duty and temperature decide
KONE specification: 15 years. Nanjing Zhuye analytics refine this:
-
Light duty (<150 starts/day, office): 18 years
-
Standard duty (150–400 starts, residential): 15 years
-
Heavy duty (>400 starts, hospital, mall): 12 years
-
High ambient (>45 °C, rooftop MRL): 10 years – capacitor life halves every 10 °C rise.
Replace immediately if:
-
STATUS LED red steady – IGBT desaturation or over-temperature
-
DC bus droops below 500 V under load – capacitor ESR too high
-
Burn mark around IGBT terminals – heat-sink paste dried out
-
Fan noise >65 dB(A) – bearing failure imminent
7. Eco-disposal & warranty
Return the old board in the recycling box; Nanjing Zhuye recovers aluminium, copper and gold and issues a €50 recycling credit. Every KM713140G04 ships with a 24-month replacement warranty, extendable to 60 months when you join our annual capacitor-replacement program.
