4 Start-Up Programming & Operation
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.
NOTICE: Install the inrush current suppression circuit outside the drive if the DC bus battery voltage is lower than 190 Vdc for 200 V.
NOTICE: Install the inrush current suppression circuit outside the drive if the DC bus battery voltage is lower than 190 Vdc for 200 V
class drives of models CIMR-LU20215 to 20415, 380 Vdc for 400 V class drives of models CIMR-LU40150 to 40605, and 500
Vdc for 600 V class drives of models CIMR-LU50099 to 50200. Failure to comply will cause the soft-charge bypass relay to remain
open and result in damage to the drive.
Using a Single-Phase, 230 Vac UPS (Uninterruptable Power Supply)
Follow the instructions when using a single-phase 230 V UPS for Rescue Operation. A 230 V UPS can be used for 200 V,
400 V and 600 V class drives.
