FRONT PANEL DESCRIPTION
2.2.
2.2.1. ON/OFF POWER SWITCH
This two position toggle switch enables operation of the UPS when it is set
to the “ON” position. When set to the “OFF” position, the LEDs will be OFF
and there will be no voltage present on any of the connector terminals,
making the UPS safe for installation or transport.
Note that when the toggle switch is in the “ON” position, voltage may still be
present at the DC output terminals even when the input terminals are
disconnected from power. Do not transport or attempt to make connections to
the terminals when the toggle switch is in the “ON” position.
Warning:
A disconnect switch shall be provided by others for DC input circuit
and shall be in accordance with the National Electric Code, ANSI/NFPA 70.
2.2.2. DC POWER INPUT
The two screw terminals above the legend marked “INP” are to be connected to an
external DC power supply. The terminal marked “+” is to be connected to the positive
supply line and the terminal marked “-“is to be connected to the system ground. The
combined current draw of the UPS and the load shall not be any greater than 3.7A.
The operating input voltage range is 24 to 28VDC. The input is protected with an
internal fuse. The terminals are designed to accept 12 to 30 AWG wire.
2.2.3. SENSE INPUT
The two terminals above the legend marked “SEN” are to be connected to the
optional load sense module, Panduit part number UPS0030LSM. Please see Section
3.2 for a detailed description of the external current sensor connections. The input
voltage range for these two connections is 21 to 28VDC. The terminals are designed
to accept 12 to 30 AWG wire.
2.2.4. DC POWER OUTPUT
The two terminals above the legend marked “OUT” are to be connected to the load.
The terminal marked “+” is to be connected to the positive supply line to the load and
the terminal marked “-” is to be connected to the system ground. Note that the “-”
terminal for the power input and power output are connected together internal to the
UPS. The current draw of the UPS load shall not be any greater than 1.6A. The
operating output voltage range is 21 to 28VDC. The terminals are designed to accept
12 to 30 AWG wire.
