Interfaces and Connections 2-25
AC Power Connection
➤ To connect LRS-24 to AC power:
1. Check that the switch on the PS is set to OFF.
2. Use the 5-ft. (1.5m) standard power cable terminated by a standard 3-prong
plug to connect AC power to the LRS-24.
3. Connect the power cable to the connector on the panel of LRSI-PSP/230/115
interface module.
4. Connect to the mains outlet.
5. Turn the POWER switch to ON to initiate the LRS-24.
DC Power Connection
➤ To connect LRS-24 to DC power:
1. Connect the power cable between the DC distribution panel and the
DC power connector of the LRSI-PSP/48 interface module.
2. Check that you have correct polarity.
DC power supply interface modules do not have power switches. Therefore, the
DC power supply will start operating when DC power is applied.
To avoid turning on LRS-24 when connecting the power cables, use an external
circuit breaker located near LRS-24 to control the supply of DC power, and
protect the DC input line. Set the circuit breaker to OFF before connecting the
DC power cable to LRS-24.
When redundant power supplies are used, it is recommended to connect the
power cables to outlets powered by different circuits.
Connection of External Phantom Feed Voltage
An external power supply unit is necessary to supply external feed voltages.
HTU-E1C/P, etc. require phantom feed voltage.
The recommended source for external voltages is LRS-PS-FEED, offered by RAD.
LRS-PS-FEED is a standalone unit, intended for rack mounting (refer to
Appendix B). To minimize cable runs, install LRS-PS-FEED directly above LRS-24
(leave 1U free space between LRS-24 and the LRS-PS-FEED). In this situation,
connect the output cable of the LRS-PS-FEED (supplied with the LRS-PS-FEED
unit) to the PHANTOM connector of the LRSI-PSP/48 or LRSI-PSP/230/115
interface module.
