3.0 SCOPE
This service manual covers the installation, servicing and operat-
ing instructions for the Patton Electronics Models 1001RPSM-RUI and
1001RPSM-R48V redundant, rack-mount power supply modules,
including the 1001RPEM-RAC and 1001RPEM-RVDC power entry
cards. The modules are part of the 1001RP series rack system.
3.1 DEFINITION OF SERVICE PERSONNEL
Qualified service personnel are defined as persons who have the
appropriate technical training and experience necessary to (A) perform
tasks in the SERVICE ACCESS AREA of the equipment, and (B) be
aware of the hazards to which they are exposed in performing a task,
and of measures to minimize the danger to themselves or other per-
sons.
4.0 SAFETY PRECAUTIONS AND OPERATING INSTRUCTIONS
To comply with the published safety standards, the following must
be observed when using or installing the power supply modules.
A.
Hazardous voltages exist in the primary circuits of AC-input
power supplies. Beware of internal lethal voltages due to charged
capacitors even after the AC input is disconnected. A minimum of
3 minutes should be allowed after input power is disconnected
before servicing the AC power supply modules.
B.
Normal operating temperature range is 0°C to + 50°C at full rated
output power. Derate linearly to 50% of full load from 50°C to
70°C.
C.
All chassis ventilation holes and fan intake openings must remain
open and unobstructed.
D.
The power supply modules are components of the 1001RP series
rack system. When installing the modules and making input con-
nections, the relevant safety standards e.g. IEC950/VDE 0805, UL
1950 and EN 60950 must be complied with.
E.
For continued safe operation, the power supplies must be operat-
ed with the appropriate fuses installed. For the AC supply, the
fuse should only be replaced by a 3.0A, 250V, time delayed,
Bussmann type GMD-3A or Wickmann type 198-1300-0-00.
For the DC supply, the fuse should only be replaced by a 5.0A,
250V, time delayed, LittelFuse type 215 005 or Wickmann type
19181-063-FS.
F.
The disconnection of the input line voltage is made by pulling the
mains plug (AC supply) or the disconnection of the DC source at
the rear power entry card (DC supply).
G.
The earth wire must be connected only to the chassis earthing
points marked with the earth ground symbol.
H.
In case of failure or malfunction, the power supplies must be
returned to Patton Electronics for servicing to ensure continued
compliance with all safety requirements
WARNING! -
High Voltage Service Access Area
The power entry cavities and power supply cards are part of a
Service Access Area. This is designated by the electric shock
symbol located on the front and rear panels. Only qualified
service personnel should be permitted to access, install,
remove, service or configure power supply modules.
