ABB 3HNA018559-001 Redundant module

Electronic drives contain electrostatic sensitive devices which can be damaged when handled improperly. Qualified personnel must follow ESD protection measures. For example: wear grounded heel and wrist straps when contacting drive. 

• The discharge time for the bus capacitors may be as long as 5 minutes. After disconnecting the drive from the ac mains be sure to wait 5 minutes before removing the drive’s cover and exposing live parts.

Follow IEC 536-2 and IEC 1140 for installation

 protection against electric shock. 

• Installation shall be performed in accordance with local electric codes, local accident prevention rules, EN 50178 and EN 61800-3. 

• Due to high leakage current this drive is to be permanently installed, i.e. hard wired. The PE connection shall be made by two separate conductors between the earth ground and the two PE terminals on the device. 

• Consult the factory before using this product on a circuit protected by a residual-current-operated protective device (RCD).

• External, supply line

 fusing is required. PC833: Bussman, MDA-20, PC834: Littlefuse, FLM 30. 

• Motor cable shield must be connected to protective earth. 

• All covers shall be closed during operation. 

• During periods of extreme regeneration or excessively high input voltage the temperature of the regen resistor may exceed 70 °C. 

• When using an external regen resistor, if regen cabling is accessible during normal machine operation, regen resistor cable should be rated at 450 VDC and shielded with shield connected to PE.
