NOTE: UNIT FACTORY WIRED FOR 120VAC INPUT AND OUTPUT.
CHANGING FROM AN INPUT OF 120VAC TO AN INPUT OF 240VAC
ON MODELS RATED AT 1000VA AND BELOW, REQUIRES THAT THE
INPUT FUSE BE CHANGED AS INDICATED. A FUSE RATED AT 240VAC
AND THE CORRECT AMPERAGE HAS BEEN PROVIDED WITH THE TOPAZ 100.

SEE NOTE AT BOTTOM OF PAGE.)
NOTE: IF YOU DESIRE TO HAVE THE OUTPUT NEUTRAL UNGROUNDED, THE BONDING JUMPER CONNECTOR BETWEEN OUPUT TERMINAL
X4 AND GROUND MAY BE REMOVED. NOTE HOWEVER, THAT THIS WILL SIGNIFICANTLY REDUCE THE COMMON-MODE NOISE ATTENUATION
OF THE ULTRA-ISOLATOR. REMOVING THIS BOND WILL ALLOW FOR 240VAC LINE TO LINE APPLICATIONS AND PEOVIDE ISOLATION.
