3 • Installation Overview

 

 

Note The DC-to-DC converter has dual power inputs (A and B power). The system continues to operate normally if either the A or B power input fails.

The system uses natural convection for heat dissipation (that is, it does not use fans). The absence of fans increases system reliability and eliminates periodic maintenance visits for fan filter replacement.Table 8 pro- vides the maximum power consumption figures for the OS-10 system under normal operating conditions.

This section explains how to connect the AC or DC power to the OS-10 system chassis.

Read the installation instructions before connecting the system to the power source.

WARNING

Do not work on the system or connect or disconnect cables during periods of lightning activity.

WARNING

The installation must comply with all required electrical codes applicable at the installation site.

Connecting AC Power to the OS-10 System

If your OS-10 system uses AC power, connect it to a 15 A at 120 VAC (or 10 A at 240 VAC) circuit with over- current protection.

Note

WARNING

The input voltage tolerance limits for AC power are 100 to 245 VAC.

•AC-connected units must have a permanent ground connection in addition to the power cable ground wire. NEBS-compliant grounding satisfies this requirement.

•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: 15A at 120 VAC (or 10 A at 240 VAC).

•The AC power supply for the OS-10 system has Double Pole/Neutral Fusing.
