Section 2.2
Connecting Power
The RS900L supports a single integrated high AC/DC or low DC power supply
NOTE
• For 110/230 VAC rated equipment, an appropriately rated AC circuit breaker must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker must be installed.
• Equipment must be installed according to applicable local wiring codes and standards.
• All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases where users
require the inputs to be isolated from ground, remove the ground braid between Surge and Chassis
Ground. Note that all line-to-ground transient protection circuitry will be disabled.
IMPORTANT!
Siemens requires the use of external surge protection in VDSL applications where the line may be
subject to surges greater than that for which the device is rated. Use the following specifications as a
guide for VDSL external surge protection:
• Clamping Voltage: 50 V to 200 V
