Installation Guidelines

• Safety First: Ensure all power to the 1336STG drive is completely disconnected and locked out before attempting to access or replace the gate drive board.
• ESD Protection: Use an anti-static wrist strap and grounded work surface when handling the PCB to prevent damage to sensitive electronic components from electrostatic discharge.
• Inspection: Before installation, verify that the replacement board is free of debris and that all pins are straight and undamaged.
• Seating: Ensure the board is firmly seated in its designated slot within the drive chassis. Verify that all ribbon cables and connectors are securely locked into place.
• Verification: After installation, perform a visual inspection of all connections before reapplying power. Follow the manufacturer's startup procedure for the 1336STG drive to ensure the new board is recognized and operating within parameters.

FAQ

Is this board compatible with other 1336 series drives?

This gate drive board is specifically designed for the 1336STG series at the 575V/125HP rating. It is not recommended for use in other 1336 series drives unless explicitly specified by Allen-Bradley documentation, as gate drive timing and signal requirements vary by drive model and power rating.

What should I do if the drive displays a fault after installation?

If a fault persists, verify that all internal connectors are fully seated and that no pins were bent during installation. Ensure the drive firmware settings match the hardware configuration. If the fault remains, consult the 1336STG technical manual for specific error code diagnostics.
