only with
250
V
fuse(s) or the same current rating and type (for
example, normal blow or time delay). Do not use repaired fuses or
short circuited fuseholders.
Always use the three-prong ac power cord supplied with this
product. Failure to ensure adequate earth grounding by not using
this cord may cause product damage.
