Installation  21  
  
   
  WARNING:
  To meet the requirements stated in NEC (NFPA 70) Articles 645- 10 and 645-11, 
a UPS installed in a computer equipment room must  be connected to a REPO circuit.  
  
   
  IM PORT ANT :
  The remote switch must be in the Off (open) position to enable power to the 
output receptacles.  
  
   
  NOTE:
  Wire the connector block using stranded, nonshielded wire (AWG #22 -  #18, or 
equivalent).  
  
Separate wire pairs are attached to a single, normally -open contact in a parallel connection. Hewlett 
Packard Enterprise recommends using different colors for the positive and negative wires.  
If a connector becomes disconnected and is reconnected with reversed polarity, a REPO is initiated. To 
avoid REPO port disconnect:  
• Minimize wire strain while connecting the REPO port.  
• Avoid allowing the wires to hang in the rear of the UPS.   
						

							 
Installation  22  
• Use tie wraps and tie wrap blocks to secure the wires tightly to the rack and t he rear of the UPS. 
 
For more information about the REPO port, see " REPO port (on page  10)". 
For information about verifying the REPO connection, see " Verifying the REPO port connection (on page 
44)".  
Connecting the ground bonding cable  l  
  NOTE:
  UPS appearance might vary depending on the specific unit installed.  
  
The ground bonding screw is provided as an attachment point for conductors. Use a ground bonding 
cable if the rack contains any conductors  for the purpose of functional grounding or bonding of 
ungrounded metal parts.   
						

							 
Installation  23  
The ground bonding cable is not included.  
 
 
 
C onnecting the UPS to utility power    
  WARNING:
  To prevent injury from electric shock or damage to the equipment:  
•   Plug the input line cord into a grounded (earthed) electrical outlet that is installed near the 
equipment and is easily accessible.  
•   Do not disable the grounding plug on the input line cord . The grounding plug is an important 
safety feature.  
•   Do not use extension cords.  
  
Connect the UPS to a grounded utility power outlet. When the UPS is plugged in, it automatically enters 
Standby mode and begins charging the batteries.  
 
Connecting devices to the UPS    
						

							 
Installation  24  
  CAUTION:
  Do not plug laser printers into the UPS output receptacles. The instantaneous 
current drawn by this type of printer can overload the UPS.  
  
Before connecting devices, verify that the UPS will not overload by checking that the ratings of the devices 
do not exceed the UPS capacity. If the equipment rating is listed in amps, multiply the number of amps by 
the selected output voltage to determine the VA.  
After verifying that the UPS will not overload (depending on your model):  
• Connect the device power cords to the output receptacles on the rear panel of the UPS.  
- or - 
• Connect devices to the output receptacles on the rear panel of the UPS using the I EC-to -IEC power 
cords included with the UPS.  
To provide additional receptacles:  
• Plug a PDU into the PDU output receptacle. The PDU output receptacle is part of load segment 1 
and can be turned off and on using power protector software  (on page 53). 
• Plug an extension bar into any IEC -320- C19 receptacle to yield eight additional IEC -320- C13 
receptacles.  
 
Connecting the UPS cord retention clips    
  NOTE:
  UPS appearance might v ary depending on the specific unit installed.  
  
  
C harging the UPS batteries  
With the UPS in Standby mode, allow the batteries to charge before putting the UPS into service.    
  IM PORT ANT :
  Charge the batteries for at least 24 hours before supplying backup power to 
devices. The batteries charge to:  
•   80 percent of their capacity within 3 hours  
•   100 percent of their capacity within 48 hours  
  
  
						

							 
Installation  25  
Starting power to the load  
Start power to the load by placing the UPS in Operate mode  (on page 40).   
  IM PORT ANT :
  AC power must be available the first time the UPS is started.  
  
 
I nstalling the ERM in a rack  
Before installing the unit, review and adhere to all warnings provided in " Precautions (on page  12)."   
  W
ARNING:   A risk of personal injury or damage to the equipment exists. Uneven loading of 
equipment in the rack might cause the rack to become unstable. Install the heavier 
components first, and then continue to populate the rack from the bottom to the top.  
  
1.  Install the mounting rails.  
2. Install the mounting ears on the chassis using the screws provided.  
 
3. With one person on each side, lift the chassis to rail level and slide the chassis on the mounting rails.   
						

							 
Installation  26  
4.
 
Attach the chassis to the rack using the supplied  screws.

Instal lation 28  
Connecting the ERM to the UPS  
1. Remove the screws, and then remove the ERM connector bracket from the  UPS. 
 
2.  Connect the ERM cable (2) in the socket (1) at the rear of the UPS.  
  
						

							 
Installation  29  
3.
 
Attach the ERM connector bracket to the UPS as a cord retention bracket for the ERM cable.  
 
4.  To install a second ERM:  
a. Remove the ERM connector bracket from the first ERM.  
b. Connect  the cable from the second ERM into the socket at the rear of the first ERM. Up to two 
ERM units can be connected.   
c. Attach the ERM connector bracket to the first ERM as a cord retention bracket for the ERM cable.   
Switching on the ERM circuit breaker  
  
Charging the ERM batteries  
Connect the UPS to a grounded utility power outlet. When the UPS is plugged in, the unit automatically 
enters Standby mode and begins charging the ERM batteries. Allow 48 hours for the ERM to fully charge.
