517EPS1 External Power Supply Installation
Instructions
Figure 1: 517EPS1

General

The compact 517EPS1 power supply is designed to supply
power to two fully loaded 517R1 card cage racks. It is 19
inches (483 mm) wide and mounts in EIA standard 19-inch
racks. It is one rack unit (1 RU or 1.75 inches or 44 mm) high.

Capacity

The 517EPS1 provides two power outputs, each rated at 6.0 A.

Safety considerations

The input voltage to the 517EPS1 is 115–230 V (50 to 60 Hz).
Input power is supplied through an AC line cord with a three-
pin grounding plug.
WARNING: Do not modify the plug by removing the grounding
pin. Ensure that the outlet is properly grounded to an earth
ground.
Consider the overall loading of the branch circuit before
installing the power supply into the rack.
WARNING: This is not a user-serviceable product. There are
hazardous voltages inside. It should NOT be opened by the
user. Refer all servicing to factory trained or authorized
personnel only.
Do not block power supply vents or otherwise restrict airflow
when installing the unit in a rack.

Installation

Installation consists of physical installation in a 19-inch (483
mm) instrument rack and electrical connections.
P/N 1073567-EN • REV A • ISS 14NOV18

Rack installation

We recommend that 1 RU (1.75 mm or 44 mm) of space be left
between the 517EPS1 and any racks above and below it. This
provides improved circulation of cooling air. Slide the power
supply into the rack from the front. Secure it with four screws
suitable for the rack.

Electrical connections

Electrical connections consist of connections to the card cage
rack or racks being supplied from the 517EPS1, dry contact
connections to remote alarm devices, alarm input ocnnections
from the supported racks, and input power connection.
Note: Make all the connections described in steps 1 through 3
before connecting the 517EPS1 to a power source (step 4).
1. The two screw terminal strips on the rear panel are
labeled DC OUTPUT A (right side) and DC OUTPUT B
(left side). Two interconnecting cable assemblies are
supplied with each 517EPS1. The three conductors in the
cable assembly are color-coded to the labels on the screw
terminal blocks. Attach the cable assembly as follows:
a. Connect the red, white, and black wires to the RED,
WHT, and BLK screw terminals, respectively. Refer to
Figure 2 on page 2 and Table 1 on page 2.
b. Plug the other end of the cable into the mating
connector on the rear of the card cage.
c. Repeat steps a and b above for the second terminal
strip and the remaining cable assembly.
2. For a redundant power supply only: The two independent
channels of the 517EPS1 may be combined to provide a
redundant power supply. Total output in this configuration
is 6 A at 13.5 VDC. Connect the wiring as follows:
a. Connect the BLK terminal of DC OUTPUT A block to
the BLK terminal of DC OUTPUT B block.
b. Connect the RED terminal of DC OUTPUT A block to
the RED terminal of DC OUTPUT B block.
c. Connect only ONE of the prewired harnesses to either
terminal block A or B as described in step 1.
3. The two screw terminals labeled RELAY are the outputs
for the dry contact relay for remote alarm announcement.
The relay is normally open (NO) and closes when the
optics in one of the rack-mounted receivers fails. Connect
the external alarm equipment to the 517EPS1 according to
Table 1 on page 2. The contacts are rated at 30 VDC, 0.5
A resistive.
