4.6 Setup Procedure for Elevator Applications
Select the configuration that matches your application. Follow the corresponding instructions for wiring and drive
settings. For configurations not covered in the list above, contact your Yaskawa representative or our sales office directly
for consultation.
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Never remove or install option cards
or attempt to replace the cooling fan while the drive is switched on. Make sure that the drive and all devices connected to the drive
have been shut off prior to performing and type of maintenance or wiring. After shutting off the power, wait for at least the amount of
time specified on the drive before touching any components or perform wiring. The internal capacitor remains charged even after the
power supply is turned off.
NOTICE: Be sure to thoroughly read the instructions for wiring and magnetic contactor sequence described in this section before
setting up the drive for Rescue Operation. Failure to follow these instructions can damage the drive.
NOTICE: Refrain from using Rescue Operation for extend periods of time. Rescue Operation uses a low DC bus voltage, which can
cause the cooling fan to shut off temporarily during Rescue Operation. Continuing to operate under these conditions can trigger an
overheat fault and damage the drive.
