Option for the rear panel view of the 1U model power source showing the location of
the connectors and Figure 2-8. Rear Panel View, 2U Chassis . Table 2-1 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 0.
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. In a unit with the standard
Non-Isolated Analog Interface, the signals of 44 pin analog
programming and external user interface connector, would float at
the same potential as the negative output terminal. Damage might
occur if the signals of the Non-Isolated Analog control connector are
connected to an external ground referenced device, due to
unintentional ground loop
currents that this connection could
generate. To correct ground loop problems, it is advised to use the
optional Isolated Analog Interface to isolate the external signals from
