IMPORTANT SAFETY INSTRUCTIONS—–SAVE THESE INSTRUCTIONS

Follow these safety precautions when connecting multiple hardware components to power sources.

WARNING: To reduce the risk of fire, electric shock and damage to the equipment:

HIGH LEAKAGE CURRENT. To reduce the risk of electric shock due to high leakage currents, ensure that there is a reliable grounded (earthed) connection before connecting power distribution products to AC power. If a large number of products will be connected to a single PDU, it may be necessary to conduct an evaluation of the installation to verify the total amount of leakage current. The total combined leakage current should not exceed 5 percent of the input current for the PDU and associated load.

• Connect only to a circuit providing branch circuit overcurrent protection of appropriate current rating.

• Connect the input power cord to a grounded (earthed) electrical outlet that is located near the equipment and is easily accessible.

• Be sure all circuit breakers are in the off position before connecting input power. Be sure that the devices connected to the Panduit PDU are adjusted for, or
  otherwise capable of, operation from the same line voltage supplying the PDU. Failure to verify the voltage can lead to severe equipment damage.

• Do not overload the PDU. The total input current rating of all equipment connected to each output cannot exceed the total output rating marked on the PDU.

• Use only the hardware provided to install the PDU.

• To reduce the risk of fire or electric shock, install this PDU in a temperature and humidity-controlled, indoor environment, free of conductive contaminants. Do not operate near water or excessive humidity (90% maximum noncondensing).

• Ambient temperature must not exceed 0°C to 60°C (32°F to 140°F).

• The internal components can become extremely hot during operation. Allow sufficient time for the PDU to cool before handling.

• Do not use a two-wire power cord in any product configuration.

• TO ISOLATE THIS EQUIPMENT, DISCONNECT THE POWER CORD.

Introduction

Classification Overview
The Panduit G5 Monitored, Switched, Monitored per Outlet, and Monitored & Switched per Outlet PDUs (Power Distribution Units) are intelligent PDUs designed to distribute power to IT equipment installed into a rack. These PDUs are single-phase (1Ph) or three-phase (3Ph) models with electrical metering and switching capabilities.
Each PDU provides power distribution to IT loads through C13, C19 or NEMA 5-20R outlets. The quantity and location of outlets vary by model. The PDUs allow you to connect and manage these outlets from a single power connection. The PDUs can be managed from a Web interface, or a Command Line Interface (CLI), and viewed from the local display.
Panduit PDUs are designed for use with all Panduit cabinets and are compatible with most third-party data center racks. The PDU models vary in form factor with several mounting configurations available.

Panduit Monitored PDU: Provides aggregate power monitoring to quickly identify potential power issues and reclaim available or under-utilized power capacity.

Panduit Switched PDU: Provides aggregate power monitoring and outlet level switching capabilities for individual outlets or a group of outlets. This PDU enables power sequencing, rebooting equipment or restrict unauthorized use of individual outlets.

Panduit Monitored per Outlet PDU: Provides outlet-level power monitoring to quickly identify potential power issues and reclaim available or under- utilized power capacity at the outlet level.

Panduit Monitored & Switched per Outlet PDU: Provides outlet-level power monitoring and outlet-level switching capabilities for individual outlets or a group of outlets. Power monitoring at the individual outlet level provides actionable management data on the power consumption of each connected IT device, enabling the redeployment or decommissioning of individual servers to reclaim available or under- utilized power capacity.

Load Segment and Phase Distinction

Panduit G5 PDUs have colored receptacles to help distinguish between the different load segments and phases. All Panduit three phase PDUs have different colored receptacles (white, light gray, and dark gray) to distinguish the different phases. All Panduit PDUs with breakers have different colored receptacles to distinguish the different load segments (with one exception as noted below). For single phase PDUs with no breakers the receptacles are all black.

There is one exception to the different colored receptacles per load segment. The three phase half-height dual sided model has two different load segments on each phase as shown in the illustration below.

Power Cord Retention

Integrated Cord Retention

Most IEC C13 and C19 outlet on the PDU comes equipped with an integrated cord retention feature. This will allow you to secure the cord to the outlet without a cord retention bracket.

Grounding the PDU

Connecting the Ground Bonding Cable
Per international regulatory requirements, the primary Safety Earth Bond connection is

contained in the PDU as an integral part of the branch circuit cabling and plug. There is an external ground bonding point located on the chassis of the PDU. The ground bonding screw is provided as an attachment point for conductors. Use a ground bonding cable if the rack contains any conductors for functional grounding or bonding of ungrounded metal parts. This bonding point can also be used to bond the PDU to a known earthed reference terminal in the building. The ground bounding point is located on the surface with the receptacles on all PDUs except for the dual-sided models. These models have the ground bounding point on the surface with the circuit breakers.

Bond Power Distribution Units (PDUs) to the grounding strip or grounding bus bar. See Panduit Grounding and Bonding Jumper kits for factory-terminated options to provide a bolt-on solution.
