Powering The System; Configuring The Soundstructure Devices - Polycom SoundStructure C16 Hardware Installation Manual

Hardware Installation Guide for the Polycom SoundStructure
When the logic output is set low (off), the transistor will turn off and an open circuit will be created between
the logic output and the chassis ground preventing any flow of current, as shown in the following figure.

See Logic Examples for information on how to wire the logic interface for common logic applications.

Powering the System

Connect the AC power line to a grounded AC power main when ready to power the device and plug the
other end securely into the rear of the SoundStructure unit. Ensure the plug is securely inserted as shown
in the following figure. Upon insertion there will be some initial resistance - continue pushing until the power
cord is plugged in.
The SoundStructure units require an AC voltage supply in the range of 90-250 VAC and 50-60 Hz. Power
should be applied after any plug-in cards are installed.
As there is no power switch on the SoundStructure devices, once power is connected, the system will begin
the boot-up process.
