Checking the direction of the rotating field

Check the correct direction of the rotating field of the

power supply when first making the connection and after

any changes to the electrical connection.

The connector is wired for a clockwise rotating field

when shipped.

While pressing the OFF button switch on the master

switch. If correctly wired, the display reads

VERSION: Vx.xx

and then

SYSTEM OFF

If the wiring is incorrect, the message

SYSTEM ERROR

is displayed. After pressing the SELECT button the mes-

sage

Phase/Fuse ERROR

is displayed. As this error message also appears if one

of the fuses (6/12) has blown, first check the fuses. If

they are OK, disconnect the power from the power leads

and reverse two phases on the power supply connec-

tion.

Switch off the main switch.
