Specifications
Overview
The Vertiv Basic Rack PDU products are Power Distribution units (PDU) intended for connection
to a 30 Amp AC Mains circuit. The PDUs are designed to be powered by a single phase AC input
circuit. The Vertiv Basic Rack PDUs covered by this manual are available in vertical or horizontal
configurations rated 208-240V and can be optionally configured with a Vertiv Power Meter that
provides local monitoring and display of Current, Voltage,Wattage, and Power Factor.

Installation
Instructions
1. Using appropriate hardware, mount PDU to rack (see Mounting section for additional
instructions.
2. Plug PDU into de-energized 30 Amp branch circuit receptacle.**
3. Connect devices into PDU’s output receptacles. It is recommended that the devices are
turned off until all devices are connected to PDU
4. Turn on branch circuit to energize PDU.
5. Power on devices. Sequential power up is recommended to avoid high inrush current.
**Branch Circuit should be sized based on the PDU’s nameplate electrical rating. A 24 Amp
rated PDU is intended for use on a 30 Amp Branch Circuit. For Global Units a 32 Amp rated
PDU is intended for use on a 32 Amp Branch Circuit.
Guidelines
 If the PDU is installed in a cabinet the ambient temperature of the rack should be no greater
than 45C.
 Install the PDU such that the amount of airflow required for safe operation of equipment is not
compromised.
 Mount the PDU so that a hazardous condition is not achieved due to uneven mechanical
loading.
 Follow nameplate ratings when connecting equipment to the branch circuit. Take into
consideration the effect that overloading of the circuits might have on over-current protection
and supply wiring.
 The PDU relies on the building installation for protection from over-current conditions. A
certified overcurrent protection device is required in the building installation. The overcurrent
protection device should be sized according to the PDU’s nameplate ratings and local/national
electrical codes.
 Reliable earthing of rack-mount equipment should be maintained. Particular attention should
be given to supply connections other than direct connections to the branch circuit. The PDU
must be connected to an earthed socket-outlet.***
 The PDU is intended for Restricted Access Locations only and only qualified service
personnel should install and access the PDU.
 For pluggable equipment, install the PDU so that the input plug or appliance coupler may be
disconnected for service.
 Sequential power-up of devices powered by the PDU is recommended to avoid high inrush
current.
 Caution: Disconnect all power cords before servicing.
 The PDU is intended for use with TN, TT, or IT power supply systems
***XP Series PDUs may optionally be configured as Isolated Ground units. All Isolated
Ground units will be shipped with an enclosure grounding cable. This cable must be
connected between the enclosure and a reliable safety ground.

Optional Local Monitoring
Power Meter
The Vertiv PM-1 power meter is a low-power, high accuracy meter capable of measuring true RMS Current,
Voltage, Power, and Power Factor. These values are individually shown on an easy to read, 4-digit LED
Display, which continuously scrolls through the four different measured values. Each one of these displayed
parameters is defined below. The Power Meter will automatically begin cycling through the displayed values
when the PDU is connected to AC Mains power.
 Current: PDU output current draw measured in true RMS Amps
 Voltage: PDU output voltage measured in true RMS Voltage
 Power: PDU output power measured in Watts –referred to as real or active power  
 Power Factor: Ratio of real PDU output power to apparent PDU output power****  
Power Meter Display
****Real power is the power in a circuit that is transformedfrom electric to non-electric
energy, while apparent power is the total power supplied to the circuit.
Current Meter
The Vertiv CM-1 current meter is a low-power, high accuracymeter capable of measuring true
RMS Current. The value of current is continuouslyshown on an easy to read, 4-digit LED Display.
The Current Meter will automatically begin to display value of output current when the PDU is
connected to AC Mains power.
