Installing The Switchable Power Supply In The
DXP Plus Common Equipment Cabinet
1.0 Introducing The Switchable Power Supply
This publication discusses the installation of the switchable IEC 950 approved 120/230 volt power supply
assembly for the DXP Plus main and expansion common equipment cabinets. The voltage ranges of this power
supply assembly is as follows:
•
90–129 VAC at 50/60 Hz
•
200–254 VAC at 50 Hz
The power supply assembly is packed separately from the common equipment cabinet; therefore, you should
unpack and carefully inspect it for shipping damage and notify the shipper of any damages you find. Also, verify
that the package contains all parts and accessories needed for proper installation and operation.
Refer to IMI66–105, Installation Instructions DXP Plus Main Cabinet Assembly for complete installation
instructions of the main DXP plus cabinet and to IMI66–106, Installation Instructions DXP Plus Expansion
Cabinet Assembly for complete installation instructions of the DXP plus expansion cabinet.
The power supply assembly is protected with a 6.3A, 250V slow-blow fuse. A replacement fuse must have the
same rating.
NOTE: Both the switchable power supply assembly employ electronic switching circuitry in their design. During
operation, power supplies of this type generate an audible sound from their switching regulators. This
sound is normal and is not an indication that the power supply is operating improperly.
