Putting the UL notice label
for the Alpha series SERVO
FANUC Alpha series SERVO AMPLIFIER has been authorized its compliance to UL/c-UL
marking through UL, a competent third party certification body, i.e. compliance to standards of
UL 508C for the US and C22.2, No. 14 for Canada.
The authorization, though, includes specific markings on the amplifiers additionally to
conventional markings. Those are shown below but there is not enough marking space for them
on each face-plate of the amplifier modules.
Then we decided to ask customers for applying the UL relevant marking label at the inside
wall of machine tool cabinet which employ PSM and other modules, by attaching the label to the
PSM when shipping. Please put the label on the conspicuous location in your control cabinet.
2. CONTENTS OF LABEL
The label to be attached to the PSM is as follows. These contents are applied not only to
PSMs but also SPMs and SVMs.
The labels will be started being attached to the PSMs in November 2000.
