OnSite Series Getting Started Guide 3 • Installation Overview

Powering On the OS-10 System with AC Power

To power on the OS-10 system using AC power, follow these steps:

1.Connect the AC power cable to the OS-10 system and then to the wall outlet.

2.Turn the power switch on the back panel of the OS-10 system to the ON position.

Note 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.

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.

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.

WARNING

Table 9 summarizes the wiring requirements for the OS-10 system chassis with a DC-input power supply.

Note For installations compliant with the National Electric Code, an AWG 14 (2.0 mm2) wire is required for DC input and safety ground wire.

Table 9. DC Wiring Requirements for the OS-10 System Chassis

DC Nominal Input	DC Input Wire Size	Safety Ground	Over-Current Protection
		Wire Size
–48 VDC at 2.0 A	AWG 18 (1.0 mm2)	AWG 14 (2.0 mm2)	15 A

Note The input voltage tolerance limits for nominal –48 VDC power sup- plies is –36 to –72 VDC.

Wiring Procedure for DC Input Power

To connect DC power to the OS-10 system, see Figure 13 and follow these steps:

	•Connect the DC input wires to the OS-10 system with the following wiring
	sequence.
WARNING	•Figure 13 shows the terminal block for the DC power supply on the OS-10
	system. Wire the DC power supply as shown.
