Do not route the control cables in the same conduit where the power cables are Installing the Inverter 19 Installation routed. Use a separate conduit for the control cables. • Incoming power cables must be connected to the R, S, and T terminals. Connecting incoming power cables to other terminals will cause internal damage to the inverter. Motor cables must be connected to the U, V, and W terminals. The correct phase rotation is not necessary. • Do not install phase advance capacitors in the inverter output and uninstall them if they had been previously installed. Phase advance capacitors in the inverter output causes inverter overcurrent fault trip. • B1 and B2 terminals on the main terminals block are for connecting braking resistors only. Do not connect any other device to these terminals.

(Connect a brake resistor to P2 and B terminals) U/V/W Output terminals to motor 3-phase motor (induction motor, synchronous motor) wiring connections. Note • Both P1 (+) and P2 (+) terminals are for DCP (+) connections. Installing the Inverter 21 Installation • N (-) terminal is for DCN (-) connection. It is not a “neutral” contact. • P2(+) and B terminals are for connecting a brake resistor only. Do not connect any other device P2(+) and B terminals. • Use STP cables to connect remotely located motors to the inverter. Do not use 3 core cables. • Make sure that the total cable length does not exceed 328 ft (100 m). • Long cable runs can cause reduced motor torque in low frequency applications due to voltage drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may trigger overcurrent protection devices or result in the malfunction of equipment connected to the inverter. • Voltage drop is calculated by using the following formula: • Voltage drop (V) = [√3 X cable resistance (mΩ/m) X cable length (m) X current (A)] / 1000 • Use cables with the largest possible cross-sectional area to ensure that voltage drop is minimized over long cable runs. Lowering the carrier frequency and installing a micro surge filter may also help to reduce voltage drop. • The permitted cable lengths for the combinations of motor type and switching frequency are listed in the table below. Motor switching frequency Maximum cable length 3 – 5 kHz < 330 ft (100 m) 3 – 8 kHz < 165 ft (50 m) Do not connect power to the inverter until the inverter is completely installed and the inverter is ready to operate. Doing so may result in electric shock. Installing the Inverter 22 • Power supply cables must be connected to the R, S, and T terminals. Connecting power cables to other terminals will damage the inverter. • Use insulated ring lugs when connecting cables to the R/S/T and U/V/W terminals. • The inverter’s power terminal connections can cause harmonics that may interfere with other communication devices located near to the inverter. To reduce interference, the installation of noise filters or line filters may be required. • To avoid circuit interruption or damage to connected equipment, do not install phase-advanced condensers, surge protection, or electronic noise filters on the output side of the inverter. • To avoid circuit interruption or damage to connected equipment, do not install magnetic contactors on the output side of the inverter.
