voltage, or (if it is to be powered by direct current) connect the DC terminal block
(
Figure 11 ) to –48 V battery power.

4.1 Configuring the RDS-AS for 100 to 120 VAC Operation
The RDS-AS is factory set for –48 VDC or 240 VAC operation, with “230V” showing as the
voltage setting in the power inlet module window (
Figure 12 ). To configure the RDS-AS for
100 to 120 VAC operation, perform the following:
1. Make sure the power cord is removed from the power inlet module before continuing.
2. Pry open the power inlet module door from the right side using a small screwdriver or
equivalent.
3. Remove the fuse module using a small screwdriver or equivalent.
4. Rotate the fuse module 180º so that the text “115V” will show through the power inlet
module window when the door is closed.
Note: If the total cable length exceeds 1,000 feet, termination per requirements of the
RS485 Card Adapter Specification may be required.
Note: The OUT A and OUT B –48 VDC and VAC outlet connectors are not used in this
RDS version. They are left unpowered in all modes of operation.
Warning: The RDS-AS is factory set for –48 VDC or 240 VAC operation. For 100/120 VAC
operation, refer to Section 4.1 , Configuring The RDS-AS for 100 to 120 VAC Operation.
Note: The RDS-AS is supplied with a detachable power cord for 120 VAC operation. For
240 VAC operation, consult your local electrical code for the correct type or style of power
cords required.
