Installing the Hardware Hardware Installation

Warning Use a single-phase grounded power source located within 6 feet (1.89 meters)

of the installation site.

Warning High leakage current can be caused by multiple power supplies. For this

reason, it is essential that each power cord be connected to separate branch

circuits with proper earth connections.

3.3.4 Installing DC Power Supplies

Warning The RS 32000 with DC power supplies should be installed only in Restricted

Access Areas (Dedicated Equipment Rooms, Electrical Closets, or the like)

in accordance with Articles 110-26 and 110-27 of the 1999 National

Electrical Code ANSI/NFPA 70.

To install a DC power supply in the RS 32000 perform the following steps. For DC power supply environmental

specifications, see Table 3-4. For special DC power safety considerations, see Table 3-3.

1. Ensure that the DC power supply is not powered on or connected to its DC power supply source.

2. Position the power supply between two guides, making sure that the groove at the bottom of the

power supply aligns with the guide underneath it (see Figure 3-3).

3. Slide the DC power supply all the way into the slot, firmly but gently pressing to ensure that the pins

on the back of the power supply are completely seated in the backplane.

4. Using a straight-blade screwdriver, turn the screw on the power supply’s front panel clockwise 180

degrees to lock the power supply into the chassis.
