Prerequisites for Commissioning

Prerequisites

 DANGER
ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Disconnect all power from all equipment including connected devices prior to removing any covers or doors, or installing or removing any accessories, hardware, cables, or wires.
  • Place a "Do Not Turn On" or equivalent hazard label on all power switches and lock them in the non-energized position.
  • Wait 15 minutes to allow the residual energy of the DC bus capacitors to discharge.
  • Measure the voltage on the DC bus with a properly rated voltage sensing device and verify that the voltage is less than 42.4 Vdc.
  • Do not assume that the DC bus is voltage-free when the DC bus LED is off.
  • Block the motor shaft to prevent rotation prior to performing any type of work on the drive system.
  • Do not create a short-circuit across the DC bus terminals or the DC bus capacitors.
  • Replace and secure all covers, accessories, hardware, cables, and wires and confirm that a proper ground connection exists before applying power to the unit.
  • Use only the specified voltage when operating this equipment and any associated products.
Failure to follow these instructions will result in death or serious injury.
 DANGER
ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
  • Operate electrical components only with a connected protective ground (earth) cable.
  • After the installation, verify the secure connection of the protective ground (earth) cable to all electrical devices to ensure that connection complies with the connection diagram.
  • Before enabling the device, safely cover the live components to prevent contact.
  • Do not touch the electrical connection points of the components when the module is energized.
  • Provide protection against indirect contact.
  • Connect and disconnect cables and terminals only after you have verified that the power has been removed from the system.
  • Insulate the unused conductors on both ends of the motor cable.
Failure to follow these instructions will result in death or serious injury.
