Overview

This document describes the requirements and power and safety ground cable wiring instructions for systems that are equipped with a -(48–60)V DC PowerEdge XR-series heater and -(48–60)V DC power supply. This document includes both United

States NEC and European (IEC) wire color codes for 2 wire ungrounded DC power supplies.

CAUTION:

1. This installation should only be done by a qualified licensed electrician. Do not attempt to connect DC Power or install safety grounds yourself. All electrical wiring must comply with applicable local or national codes and practices.

2. Once an electrician completes the installation, the power supply input plug and heater input plug can be plugged and unplugged like a normal AC power cable. The DC power must be turned off before attempting to plug and unplug either input plug.

3. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team.

Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.

4. Wire the unit with copper only (unless otherwise specified), 10 American Wire Gage (AWG) 105/30 stranded wire rated minimum 90C in parallel for source and return.

5. Protect the -(48–60)V DC (1 wire) with a branch circuit over-current protection rated 30 A for DC with a high interrupt current rating.

6. The heater must only be connected to a -(48-60)V DC power source classified by SELV or ES1 output in accordance with applicable national requirements for Information Technology Equipment and complies with

IEC/UL 60950-1 and/or IEC/EN/UL 62368-1.

7. Ensure that the -(48–60)V DC source is efficiently secured to earth (ground).

8. A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the field wiring.

Topics:

1. Assembling and connecting the safety ground wire for DC power supply and PowerEdge XR-series heater

2. Assembling the power supply input plug to the heater power cable

3. Assembling the DC input power cable for PowerEdge XR-series heater

4. Connecting the -(48-60) V DC input power cable

1. Assembling and connecting the safety ground wire for DC power supply and PowerEdge XR-series heater

About this task

NOTE: This product is intended to be used in CBN (Common Bonding Network) applications.

Steps

1. Strip the insulation from the end of the US NEC green/yellow (European IEC green with a yellow strip) wire, exposing approximately 0.175 inches (4.5 mm) of copper wire.

2. Using a hand-crimping tool, crimp the 90-degree ring-tongue terminal of M4 stud size (not supplied) and suitable for 10

AWG insulated copper wire to the US NEC green/yellow (European IEC green with a yellow strip) wire.

3. Remove the M4 nut and associated hardware from grounding post/stud.

4. Connect the safety ground to the grounding post/stud using the M4 nut, spring washer and locking/star washer.

5. An individual safety ground wire should be connected to the power supply and to the PowerEdge XR-series heater.

NOTE: The system that is shown below is indicative only and may not match the actual system that you purchased.

2. Assembling the power supply input plug to the heater power cable

To connect the power supply input plug to the heater power cable, perform the following steps:

Steps

1. Insert the heater power cable black wire marked as -48 V DC into power supply input plug housing position marked -48V.

The crimp terminal must be properly oriented as shown in the image.

2. Insert the heater power cable red wire marked as RTN into power supply input plug housing position marked RTN. The crimp terminal must be properly oriented as shown in the image.

3. Secure both black and red wires into the input plug using the screws. Tighten the screw to an approximate torque of 23.9

LB-in +/-5% (2.7 N-m +/-5%) and insert the cap over the screws. The screw is intended to go through the hole in the crimp terminal. Ensure that the cap is inserted properly, and the crimp terminal is secured with the screw by lightly tugging on the cables.

CAUTION: Damage can occur if the crimp terminals are not fully inserted into the plug before tightening the screws.

WARNING: Failure to follow the documented assembly instructions could result in potential property damage, personal injury, or death.

3. Assembling the DC input power cable for

PowerEdge XR-series heater

To construct the DC input power cable for the heater, perform the following steps:

Steps

1. Strip the insulation from the ends of the DC power wires exposing approximately 0.394 - 0.433 inches (10 - 11 mm) of copper wire.

2. Insert the US NEC black (European IEC gray) wire into input plug housing position marked DC IN -48V.

3. Secure the wire using the heater input plug screw. Tighten the screw to an approximate torque of 7 LB-in +/-5% (0.8 N-m

+/- 5%).

4. Insert the US NEC red (European IEC brown) wire into input plug housing position marked DC IN RTN.

5. Secure the wire using the heater input plug screw. Tighten the screw to an approximate torque of 7 LB-in +/-5% (0.8 N-m

+/- 5%).

CAUTION: Ensure that all cable wire strands are inserted into the input plug housing position. Non-contained wire strands can short and cause potential damage. Cable wire strands should not be visible after proper installation.

WARNING: Failure to follow the documented assembly instructions could result in potential property damage, personal injury, or death.

2. Slide the PowerEdge XR-series heater into the PSU bay 1 (left bay) until the release latch snaps into place.

CAUTION: The PowerEdge XR-series heater must be installed in PSU bay 1 (left bay).

3. Insert the heater input plug into the heater connector and press the input plug until it clicks in place. Use a VELCRO ® strap to loop the cable to the PowerEdge XR-series heater handle.

CAUTION: The input plug must be fully inserted into the heater connector.

WARNING: The DC power source must be turned off before inserting the heater input plug. The PowerEdge

XR-series heater is not hot pluggable.

4. Insert the power supply input plug into the -(48-60)V DC power supply connector and press the plug until it clicks in place.

CAUTION: The input plug must be fully inserted into the power supply connector.

WARNING: The DC power source must be turned off before inserting the power supply input plug. The DC power supply is not hot pluggable when used with a PowerEdge XR-series heater.
