Installing the Rear Support Brackets
In some cases, (mobile trucks, etc.) it may be desirable to also support the rear of the SRG-4500. The rear support
bars can be attached to the SRG-4500 in six possible positions. ( Figure 4.1 )
Figure 4.1 Installing the Support Brackets
To install the support brackets
1. Choose the position that suits the cabinet depth and will give approximately a 0.5” projection beyond the
previously mounted bracket.
2. Using four screws per bracket, as shown in Figure 4.1 , attach both bars.
3. Mount the frame to the front rails of the rack cabinet using rack screws.
4. At the rear of the cabinet, slide the bracket slots over the rear of the support bars and secure to the cabinet rear
rails with rack screws. Refer to the SRG-4500 Quick Start Guide for more information.
5. If your SRG-4500 was shipped with a Breakout PCB, refer to “ Installing the Breakout PCB ” on page 123 for
additional installation details.
Connecting Power
The SRG-4500 operates from a single-phase power source with the neutral conductor at or near earth ground. The
line conductor is fused for over-current protection. A protective ground connection through the grounding
conductor in the power cord is essential for safe operation. Safety earth studs are also provided for earth bonding
the chassis if you so require.
Your SRG-4500 includes the N+1 power option (PS-4500), you need to provide two power connections. For full
power security, these should be on separate, independent and secure power grids. However, you still gain the
security of power supply failure redundancy if you use the same power grid for both connections.
AC Power Requirement
Check that your location provides the proper electrical power requirements as listed in Table 4.1 .
Warning
— Do not use the support brackets to carry the SRG-4500. The brackets are not primarily
designed for this purpose, and property damage or personal injury may result.
Warning
— Disconnect both power cords. If two power entry connectors are present on the rear panel,
the unit will still be powered until both power cords are removed.
Caution
— The SRG-4500 does not have a power switch. Removing the Power Supply Cord(s)
disconnects the device from the mains power. Ensure easily accessible socket outlets are available near
the unit to power the device.
