3500/15 AC and DC Power Supplies Operation and Maintenance Manual
The High Voltage DC Power Supply supports dc inputs from 88 to 140 Vdc. The
Low Voltage DC Power Supply supports dc inputs from 20 to 30 Vdc.
2.2 Single Power Supply
The 3500 will operate under fully loaded conditions with a single power supply. If
your installation will use a single power supply, we recommend that you install
the supply in the upper power supply slot.
2.3 Redundant Power Supplies
When you install 2 power supplies in a rack, the supply in the lower slot acts as
the primary supply and the supply in the upper slot acts as the backup supply. If
the primary supply fails, the backup supply will provide power to the rack without
interrupting rack operation.
Each supply provides power on an independent power distribution network. This
ensures that any failure in one power distribution network (e.g., a short in +5 volt
supply) will not affect the other supply.
Application Advisory
Triple Modular Redundant (TMR)
applications require redundant
power supplies.
2.4 CE Compliance Information
For systems installed in areas that must comply with EN61000.3.2, the equipment
shall only be used in industrial environment with a connection to the industrial
power supply network. If the system is connected to the public power supply
mains, the system must meet EN61000.3.2 by using a 3rd-party device that
provides power factor correction.
2.5 Low Voltage Directive Compliance
To comply with EN 61010-01 Low Voltage Directive the PIM Connector Shield
should be orientated properly. If the shield is not installed as in Figure 2-2,
carefully remove the shield and replace it in the correct orientation. Failure to
correctly place the connector shield will make the power terminals accessible to
an operator.
