Do not connect the equipment to the power source until the proper voltage selection
has been made. Doing so could result in electrical shock and/or damage the
assembly.
All instruments leave the factory set for 120VAC and with the line fuse removed. The correct
setting of the universal power entrance must be checked and the appropriate fuse(s) installed
before the instrument can be operated. The degasser is designed to operate with universal line
voltage of 100/230VAC ±10, 50/60 Hz through a standard wall receptacle. Voltage selection and
fusing are made at the power connector located on the rear panel of the unit.
n
The power cord should be disconnected from the instrument before removing the
cover from the input power connector. Failure to disconnect the power cord could
result in electrical shock.
n
The input power connector can be used with either a single-fuse arrangement
(100/120VAC) or a double-fuse arrangement (230/240VAC). Use the
appropriate fuse(s) for the input power source. The fuses must be identical in type
and rating to that specified. Use of other fuses could result in electrical shock
and/or damage to the instrument.
Fuses may be obtained from Micromeritics or a vendor of your choice as long as they
meet the requirements specified in this section.
