Use a GFCI type B according to IEC 60755 when leakage current protection or monitoring is required to help
protect against shock by direct or indirect contact with electrical equipment.
Failure to comply may result in injury due to electrical shock.
Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which could
result in death or serious injury. Always use a ground wire that complies with technical standards on electrical
equipment and minimize the length of the ground wire.
Always ground the ground terminal. (200 V Class: Ground to 100
Ω or less, 400 V Class: Ground to 10 Ω or less).
Sudden Movement Hazard
Comply with proper wiring practices.
The motor may run in reverse if the phase order is backward, causing incorrect elevator direction movement and injury
to personnel.
Connect motor input terminals U, V and W to drive output terminals U/T1,V/T2, and W/T3. The phase order for the
drive and motor should match.
Install a properly controlled contactor on the input-side of the drive for applications where power should be
removed from the drive during a fault condition.
Improper equipment sequencing could result in death or serious injury.
Fire Hazard
Drive Short-Circuit Current Rating
Install adequate branch circuit protection according to applicable local codes and this Installation Manual.
Failure to comply could result in fire and damage to the drive or injury to personnel.
The device is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 240
Vac maximum (200 V class) and 480 Vac maximum (400 V class) when protected by branch circuit protection devices
specified in this manual.
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
Improperly tightened terminal screws can also cause erroneous equipment operation.
Do not use improper combustible materials in drive installation.
Failure to comply could result in death or serious injury by fire.
Attach the drive or braking resistors to metal or other noncombustible material.
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire. Verify that the rated voltage of the drive matches the
voltage of the incoming power supply before applying power.
The braking resistor connection terminals are B1 and B2. Do not connect a braking resistor directly to any
other terminals.
Improper wiring connections could result in death or serious injury by fire.
Do not connect the AC power line to the output motor terminals of the drive. Failure to comply could result in
death or serious injury by fire as a result of drive damage from line voltage application to output terminals.
• Do not connect AC line power to output terminals U, V, and W.
• Make sure that the power supply lines are connected to main circuit input terminals R/L1, S/L2, T/L3 (or R/L1 and S/
L2 for single-phase power).
