2.2 Electrical Connections

This section provides cabling requirements for interfacing to the RC3050. Note that cables should be
made long enough to allow the unit to be open while still connected to the system.
The following sections supply a schedule of connection requirements. Note that the pinout requirements
for J1, J3, and J7 are the same as required for RC3000 installations and therefore should not require
rework of those cables for retrofitting to the RC3000. The backpanel diagram shows the location of the
connectors.

Note that holes in the backpanel that are used for additional connectors by the RC3000 are covered by
metallic tape for the RC3050.

2.2.1 Power Entry

J6 is an IEC power connector for supplying AC power to the RC3050.
The RC3050 is shipped from the factory with an line cord appropriate for the line voltage selected. If the
line cord received with the unit is not appropriate for the power available at the installation site, the
installer should check the controller to ensure that the proper line voltage has been selected.
The RC3050A can be configured to operate on either 115 VAC or 230 VAC. The AC input voltage the
unit is currently configured for is displayed in a window located in the fuse holder. To change the AC
input voltage selection, remove the fuse holder and reverse the jumper assembly (on which the '115'
and '230' labels are located).
To convert AC Voltage. Switch the power off at the front panel. Remove the IEC power cord from the
back panel power entry module. With a small straight-blade screwdriver, remove the fuse drawer from
the power entry module. With the same tool, remove the small plastic circuit card. Rotate the card so
that the desired operating voltage will be displayed through the front of the fuse drawer and reinsert the
card so that it firmly seats into the power entry module.
NOTE: The RC3050B can only be configured for 115 or 230 VAC since the internal DC motor
controller module is different for each voltage. The fuse holder is glued into the correct voltage
position and cannot be modified as in the RC3050A case.
The fuse holder is designed to accommodate 1/4" by 1 1/4" fuses. "Slow Blow" type fuses should be
used. The following table shows the appropriate fuse for each model and line voltage combination.
