LRS-24 Installation and Operation Manual Appendix B LRS-PS-FEED Power Supply
Installation and Operation B-5
Rack Installation
Position the LRS-PS-FEED unit above LRS-24, leaving at least 1U free space, and
fasten the unit with four screws to the rack side rails.
Power Connection
Note that only the AC-powered LRS-PS-FEED has a POWER (On/Off) switch; the
DC-powered unit does not have a power switch, and therefore it will start
operating when DC power is applied.
➤ To avoid turning on LRS-PS-FEED when connecting the power cables:
1. Before connecting LRS-PS-FEED to AC power, set the On/Off switch on the
LRS-PS-FEED panel to Off.
2. Use an external circuit breaker located near LRS-PS-FEED to control the supply of
DC power, and protect the DC input line. Set circuit breaker to Off before
connecting the DC power cable to the LRS-PS-FEED.
AC Power Connection
Supply AC power to LRS-PS-FEED through the 5 feet (1.5m) standard power cable
terminated by a standard 3-prong plug.
Connect the power cable first to the connector on the panel of the LRS-PS-FEED,
and then to the mains outlet.
DC Power Connection
Connect the power cable between the DC distribution panel and the
DC power connector of the LRS-PS-FEED. Pay attention to correct polarity.
Phantom Voltage Connection
Connect the connector of the Phantom Out cable of the LRS-PS-FEED to the
designated Phantom Feed connector of the LRSI-PSP* interface module installed
in the LRS-24.
* Interface module version, for example, LRS-PSPF1, LRS-PSPF2, etc.
Operation
➤ To operate LRS-24 with LRS-PS-FEED:
1. Turn on LRS-24 before powering up LRS-PS-FEED.
2. After LRS-24 is operating, apply power to LRS-PS-FEED. The Power indicators
of the LRS-PS-FEED light up.
3. When turning off the system, first turn off LRS-PS-FEED; then turn off LRS-24.
