Using the S-240P
The S-240P is designed to be used with the S-4000S or S-4000H units that are part of an RSS S-4000 Modular
Digital Snake. When properly connected, the S-240P will supply power to, and allow the continued operation
of, the S-4000 unit that it is connected to in case the internal power supply of the S-4000S or S-4000H is
damaged and fails; or if the power switch on the unit is accidentally turned off. In these rare and unexpected
cases, the S-240P will allow the S-4000 unit to keep working and the audio of the system will continue without
interruption. For this reason, we suggest that, whenever possible, the S-240P should be plugged into a circuit
that is separate from the circuit supplying the power to the S-4000S or S-4000H.
The S-240P can be used in a free standing configuration, or rack-mounted using the installed rack-mount
brackets.
The S-240P unit has an AC cord clamp to prevent the cord from being pulled out accidentally.
Use the following procedure to secure the power plug.
1.
Connect the power cord to INT. POWER AC INPUT on the rear panel.
2.
Lower the power cord clamp to secure the power cord plug.
3.
Connect one end of the supplied AC power cord to a grounded AC outlet.
About the S-240P
When this is the case, even if there is a failure of the power line to the S-4000, the audio of the S-4000 Digital
Snake system will continue without interruption using the power supplied from the S-240P. The redundant Ether-
net connectors provided with all S-4000 units and the optional S-240P have been designed to provide the great-
est security possible to an RSS Modular Digital Snake system.
Installation Notes
Whatever method you choose, be sure to provide adequate air flow around the units, and be sure not block the
intake and exhaust vents. Failure to do so will result in the units overheating, causing automatic shutdown and
possible damage.
For the location of the intake and exhaust vents, see “S-240P Front Panel” (p. 6).
