Attaching the AC Line
Note:
8578AS loads are shipped from the factory foramtted for 115
VAC operation. For 230 VAC operation, the fuses and fuse drawer must
be changed to use the two pole fuse drawer included with the unit and
the two 3.15 Amp fuses also supplied. The power entry module must
also be set to 230 volts.
A standard AC power cord is required.
The AC power supply may be either 115 or 230 volts depending on the unit
requirements. AC is supplied to the power entry module by means of a cable
and matching plug. For proper protection, if a 3-wire type plug and outlet is not
used, fasten the green wire at the supply end to a satisfactory ground. Do not
apply RF power to the unit unless the power cord is connected and the ON/OFF
switch is in the ON position.
Note:
Ensure the proper fuses are used. The unit is shipped with
fuses installed for 115V usage. If the unit is to be used at 230V, install
the 3.15A fuses. See “Relpacing the Fuse” on page 17.
