III — INSTALLATION

MOUNTING RACK ADAPTER:  

The rack adapter

mounts directly to EIA-RS 310D standard 19" racks via
the two mounting ears; two screws are required per
mounting ear for proper support. 

CAUTION: Rack adapter should be mounted before
installing power supplies. 

Two 8-32 threaded holes (see Figure 2 are provided adja-
cent to each input power terminal block which can be
used for user-supplied strain relief cable clamps if desired.

INSTALLATION/REMOVAL OF HSF POWER

SUPPLIES:  

To install each HSF power supply insert

HSF power supply in selected slot until power supply
front panel is flush with rack adapter chassis. and secure
with two front panel screws on power supply. 

CAUTION: Do not overtighten these screws: max.
torque is 2 in.-lbs (0.23 N x m). 

WARNING: Removal of HSF power supply from a
“live” system must be done only by authorized ser-
vice personnel after HSF power switch is set to OFF.
Dangerous voltages may be accessible through the
open slot after a power supply is removed.

IV — WIRING

A-C WIRING:  

It is the user’s responsibility to obey all

local, national and international safety rules regarding
field-wired apparatus and the grounding of the metal
cover and case of any instrument connected to the a-c
power source. Grounding is an intrinsic part of the safety
aspect of the unit. 

SOURCE POWER:   

Source power requirements are

determined by the HSF power supply (see HSF power
supply Instruction Manual); no adjustment or modification
of the rack adapter is required. 

Source power can also be custom configured via jumpers
on the internal PC board. Contact Kepco Applications
Engineering for further details. 

Wire must be sized according to expected current. Wire
size range for each terminal block is AWG 20-10; torque
to 6 lb-in (0.6 N•M) maximum. 

CAUTION: PROTECTION

OF INPUT WIRING REQUIRES USER-CONFIGURED
SAFETY INTERRUPTS. 

The terminals are labeled L, N,

and G. Their functions are:

• Terminal G (Ground) is the safety ground con-

nection for the RA 19-(X)B. 

• Terminals L (Line Phase) and N (Neutral) are 

connected to the input power entry connectors. 
Source power is distributed to the power supplies 
according to the label on the rear panel. 

CONTROL SIGNALS:   

Access to all the control sig-

nals for each HSF power supply is provided via two 15-pin
D-subminiature I/O connectors on the rear panel of the
rack adapter (see Figure 2). Four mating connectors
(Kepco P/N 142-0449) are provided in a plastic bag. 

OUTPUT LOAD:  

Load connections to the rack adapt-

ers are achieved via two 4-terminal terminal blocks
located on the rear panel assembly. DC and –
for PS1 and PS2 are on one terminal block and + and –
for PS3 and PS4 are on the other. Wire must be sized
according to expected current. Wire gage may be
between 20 GA and 10 GA; torque to 6 lb-in (0.6 N•M)
maximum. As the length of load wires increases, ripple
and noise may increase proportionally, therefore length
and placement are critical for minimum ripple and noise. A
filter consisting of a 50mF electrolytic capacitor in parallel
with a 0.01mF capacitor must be used to eliminate
unwanted ripple and noise pickup on the load wire during
measurements. For remote sensing refer to RA 19-(X)B
Operator manual. For noise-sensitive applications the
load wires and sense wires must be twisted and/or
shielded.
