   *a	Coolant Pipe

   NOTE:

   Do not damage the coolant pipes.

   HINT: 

   • Use a piece of cloth as shown in the illustration to prevent the coolant (for inverter) from spraying.
   • Cover the air inlet port with a piece of cloth to minimize air leakage.

1. Using a piece of cloth, clean the outside of the inverter with converter assembly and around the bolts.
   NOTE:

   To prevent foreign matter from entering the inverter with converter assembly, make sure that the protective tape is not partially removed.

See step  9

1. Using a voltmeter, measure the voltage between the terminals of the 2 phase connectors.

   Standard Voltage

   0 V

   HINT: 

   • Use a measuring range of DC 750 V or more on the voltmeter.
   • If it is confirmed that high-voltage is not being applied to the inverter with converter assembly, removal/installation can be performed without using insulated tools or gloves after this step.
2. Apply protective tape to the area that was exposed when the inverter terminal cover was removed.

2. Connect the ground clip of the SST (anti-static mat) securely to a ground point provided in the workshop or on a workbench (anchor bolt).
   • SST: 09890-47010 

   HINT: 

   If the ground clip cable is too short, use an extension cable.

3. Connect the ground clip of the antistatic wrist strap securely to the specified point of the antistatic mat.
4. After removing the converter cover, perform work with bare hands to prevent damage from static electricity and entry of foreign matter.
