Rear Panel Input/ Output Connections
Figure 2-3 shows the rear panel view of the power source and locations of the rear
panel connector for the rear panel view of the 1U model power source showing the
location of the connectors. Table 2-2 provides details of the connectors located in the
rear panel of the power source.
WARNING!
High voltage present at rear panel poses risk of electrical shock. The input and
output covers maintain protection against hazardous voltages. Do not remove
protective covers on AC input or DC output. Refer installation and servicing to
qualified personnel.
WARNING!
The input and output voltages at the rear panel of the unit might be HAZARDOUS
LIVE. When rack-mounting or panel-mounting the unit, suitable safeguards must
be taken by the installer to ensure that HAZARDOUS LIVE voltages are not
OPERATOR accessible. OPERATOR access should only be to the front panel of
the unit.
WARNING!
A safety disconnect device for the AC mains input must be installed so that it is
readily accessible to the user.
WARNING!
A properly sized input overcurrent protection device must be installed at the AC
mains input, either a circuit breaker or fuse having a rating of 25% over the
maximum AC input line currents listed in Table .
WARNING!
To prevent an electrical shock hazard, a safety ground wire must be connected
from the safety ground stud on the rear panel to the AC mains ground.
CAUTION!
Under no condition should the negative output terminal exceed 600V to earth
ground. Floating the negative output terminal subjects the internal control circuitry
of the power supply to the same potential as present at the negative output terminal.
The signals of analog programming and external user interface connector are
isolated from the output terminals of the power supply.
