Intended Use
The NetSure™ RDB Rack PDU (Power Distribution Unit) is designed to deliver power to
information technology and telecommunication equipment.
Operate the Rack PDU in an indoor environment only within an ambient temperature range and a
relative humidity range as listed in 3.2 - Environmental Characteristics. Install the Rack PDU in
a clean environment, free of conductive contaminants, moisture, flammable liquids, gases and corrosive substances.
• Do not use the Rack PDU in moist environments. If the Rack PDU is exposed to moisture, immediately disconnect the Rack PDU from DC input power by opening the circuit breaker or removing
the fuse or breaker supplying DC input to the Rack PDU. Send the Rack PDU to the manufacturer for inspection.
• Do not use the Rack PDU for household applications.
Installation and Operation
Improper installation and operation may cause overheating and lead to increased fire hazard. It may also destroy the device and damage other connected systems.
• Installation and start-up must be performed by a qualified service engineer.
• Make sure that the total input current of the connected systems does not exceed the current rating specified on the rating plate of the Rack PDU.
Electrical Safety
Damaged Rack PDUs or connected cables increase the risk of electric shock or smoldering
fire.
• Check the unit for external signs of damage prior to start-up operation! Do not operate the device
if you detect any damage or other deficiencies.
• Only use the supplied DC input power cable.
Personal Safety
Careless handling increases the risk of electric shock.
• Never touch the outlets or the Rack PDU with wet or moist hands.
Service
Repairs should only be performed by qualified service technicians.
Unauthorized changes, modifications, or repairs of the device are performed at the owner’s risk and
will void all warranty claims.
• Do not open the Rack PDU.
• Please contact the nearest customer service center in case of malfunction! Damage and defects
must be repaired immediately.
• Always disconnect the unit from power before troubleshooting.

1.0INSTALLATION
The NetSure™ RDB Rack PDUs (Power Distribution Units) are designed to be installed on the left
and/or right rear frames of IT racks. They can be mounted directly to the rack or use Rack PDU
Mounting Kit P/N 547665. See 3.4 - Dimensions for hole dimensions.
1.1Shipment Inspection
Unpack the shipping container, inspect all items for damage and verify that the shipment is complete
and undamaged. Report any damage to your local Emerson representative and the carrier.
1.2Installing the Rack PDU
WARNING
!
Ensure proper grounding.
The Rack PDU’s "Ground Lead Bracket" must be ground bonded to the mounting bracket (if
used) or rack frame. The mounting bracket (if used) must be ground bonded to the rack frame.
The rack frame must be ground bonded to your site ground. This is typically accomplished
through the use of paint free areas and/or grounding washers used when mounting the
components.
1.2.1Installing the Rack PDU Directly to a Rack Frame or Existing Mounting Bracket
Installation
Install the Rack PDU directly to the rack frame or existing mounting bracket as shown in Figure 1.
Note that the supplied "Ground Lead Bracket" is to be placed between the PDU and the rack frame or
existing mounting bracket as shown in Figure 1. Use the supplied 1/4-20 screws and 1/4-20 KEPS
nuts.
1.2.2Installing Rack PDUs to a Rack Frame using the Optional Mounting Bracket
If using the Rack PDU Mounting Kit, install the Rack PDU mounting bracket to the left and/or right
rear frame of the rack using the appropriate hardware that fits to the cabinet that will be used.
Install the Rack PDUs to the Rack PDU mounting bracket that was previously installed on the frame
as shown in Figure 2. Note that the supplied "Ground Lead Bracket" is to be placed between the
PDU and the mounting bracket as shown in Figure 2.
