Bird 8640 Series Moduload RF Load Resistor
6
DC Resistance
Before first using the load, get a resistance baseline for future
maintenance. Refer to “DC Resistance” on page 14 for instructions.
Meter Rack
If the Moduload will be used with a power meter, install the meter
rack to provide a convenient place to keep the meter. Use the
supplied #6-32 x
1 ⁄
4
screws to assemble the rack. To install the rack,
remove two screws from the Moduload where the rack will be
mounted, then screw it into place with the supplied #8-32 x
3 ⁄
8
screws.
Interlock
Connection
y Use number 22 AWG (or heavier) wire for interlock connection.
Attach solderless ring terminals to the wire for ease of installation.
y Connect the interlock wires to the interlock terminal strip as
required for the transmitter.
NOTE: Interlock contact resistance could be as high as 10 ohms
for circuits drawing less than 250 mA.
AC Mains
Connection
The ac power supply required for this unit is 115/230 V, depending on
the model, @ 50/60 Hz, 1
φ . The unit is equipped with an IEC 320
“cold” (70 ° C) ac inlet.
WARNING
Disconnect the unit from all power sources before servicing.
The unit may be energized from multiple sources.
The potential for electric shock exists.
WARNING
Improper wiring could result in electric shock and death.
CAUTION
Do not operate without the interlock. Even momentary
application of RF power while coolant is not circulating could
cause immediate destruction of the load.
CAUTION
Check the local electrical code for proper ac hookup prior to
operation of the unit. Make sure the neutral or return hookup is
only used for that purpose.
WARNING
Connect the power cord to the Moduload
BEFORE connecting to ac mains.
