6.4.2.2 Replacing fuse F1

 Replace the fuse in the fuse holder in the cover panel:

old rating: 3.15 A T

new rating: 6.3 A T

 Replace the adhesive label specifying 3.15 A with the 6.3 A label from the conversion kit.

6.4.3 Checking the protective wire connections, fitting the covers

 Check that the detached protective earth wires have been reconnected correctly.

 Fit the covers.

6.4.4 Carry out the safety check to DIN EN 60 204

 When the conversion is complete, carry out a safety check to DIN EN 60 204.

 Follow the procedure described in section 2, page 146 onwards.

6.5 Converting the power supply from 3 x 208 VAC to 3 x 400 VAC

 Dock the MTC out of the placement machine.

RISK OF DEATH 6

 Disconnect the MTC from the main power supply.

 Remove the plug for the communication cable from the placement machine.

 Take suitable action to ensure that the MTC cannot be connected to the power supply during

the conversion work.

 Put up warning signs to indicate that work is being carried out on the electrical system.
