Replacing the starting capacitor

The starting capacitor is mounted next to the fan connection.
The starting capacitor is mounted on the fan assembly.
• Remove the plug connections from the starting capacitor
• Unbolt the starting capacitor
• Install a new starting capacitor in the inverse sequence

Replacing the capacitor bank

The capacitor assembly consists of three boards. Each board has a capacitor mounting element and a DC link
bus connection.
• Remove the plug connections
• Release the mechanical retaining elements (three screws: two at the left, one at the right)
• Remove the capacitor by slightly raising them and withdrawing them from the drive converter towards the
front.
The capacitors weight up to 30 kg depending on the drive converter rating.
• Install a new capacitor bank in the inverse sequence.
