Specifications
Overview
The HT Series products are Power Distribution Units (PDU) intended for connection to a 15 or 20
Amp AC Mains circuit
1
. The PDUs are designed to be powered by either a single phase or a three
phase AC input circuit. Three phase units can be configured for either a delta or wye input
connection.

Installation
Instructions
1. Using appropriate hardware, mount PDU to rack (see Mounting section for additional
instructions).
2. Plug PDU into de-energized 15 or 20 Amp branch circuit receptacle
2
.
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.
Guidelines
If the PDU is installed in a cabinet the ambient temperature of the rack should be no greater
than 60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
2
Branch Circuit should be sized based on the PDU’s nameplate electrical rating. A 12 Amp rated
PDU is intended for use on a 15 Amp Branch Circuit, while a 16 Amp rated PDU is intended for use
on a 20 Amp Branch Circuit. For Global Units a 16 Amp rated PDU is intended for use on a 16 Amp
Branch Circuit.
