2. Turn the power switch on the back panel of the OS-10 system to the ON position.
Note
CAUTION
Connecting DC Power to the OS-10 System
If your OS-10 system has a DC-input power supply terminal block on the front panel, follow the directions in
this section for proper wiring.
WARNING
Table 9 summarizes the wiring requirements for the OS-10 system chassis with a DC-input power supply.

OnSite System Installation
The green PWR (power) LED on the front panel is lit when the sys-
tem receives power from the AC source.
After turning off the AC power switch, wait for at least 3 seconds
before turning it back to the on position.
This product relies on the installation of the building for short-circuit (over-
current) protection. Ensure that the protective device is rated not greater than
15 A at 60 VDC.
For installations compliant with the National Electric Code, an AWG
14 (2.0 mm2) wire is required for DC input and safety ground wire.
DC Input Wire Size
AWG 18 (1.0 mm
The input voltage tolerance limits for nominal –48 VDC power sup-
plies is –36 to –72 VDC.
