DS200TCTGG1AFF gas turbine electric card

Mounting instructions: 1. Stop the drive. 2. Switch off the power supply of the drive and all dangerous voltages connected to the inputs and outputs. 3. Wait for five minutes to ensure that the capacitors in the intermediate circuit have discharged. 4. Remove the front cover of the drive. 5. Ensure that the mains cable, motor cable and capacitor bank (UDC+ and UDC-) are not powered. 6. Locate the position for the module (see the user’s manual of the drive). Fasten the mounting rail to its place if not already installed. Observe the free space requirements for the module (min. 10 mm from adjoining equipment/wall). 7. Push the module onto the rail. The module can be released by pulling the locking spring with a screwdriver

This chapter contains: 

• Cabling instructions • Instructions for bus termination • Connection and earthing instructions for the NMBA-01 Module and earthing instructions for the bus cable. WARNING! Before installation, switch off the drive power supply. Wait for five minutes to ensure that the capacitor bank of the drive is discharged. Switch off all dangerous voltages connected from external control circuits to the inputs and outputs of the drive.

Cabling

 Arrange the bus cables as far away from the motor cables as possible. Avoid parallel runs. Use bushings at cable entries. Handle the fibre optic cables with care. When unplugging optic cables, always grab the connector, not the cable itself. Do not touch the ends of the fibres with bare hands as the fibre is extremely sensitive to dirt. The maximum long term tensile load for the fibre optic cable is 1 N. The minimum short term bend radius is 25 mm. Bus Termination The built-in terminating resistors must be switched on if the NMBA-01 module is installed at the end of the bus. Otherwise the resistors must be switched off. Terminating resistors prevent signal reflections from the bus cable ends.
