C onnecting the USB communications port  
  
Connecti ng the REPO port     
						

							
 
Installation  22 
  WARNING:
  The pins on the REPO port are polarity sensitive. Be sure to verify polarity while 
connecting the REPO port.  
   
   
  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.  
  
   
  IMPORTANT:
  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. HP 
recommends using different colors for the positive and negative wires.  
If a connector becom es disconnected and is reconnected with reversed polarity, a REPO is initiated. To 
avoid REPO port disconnect:   
						

							
 
I nstallation  23 
• Minimize wire strain while connecting the REPO port.  
• Avoid allowing the wires to hang in the rear of the UPS.  
• Use tie wraps and tie wrap blocks to secure the wires tightly to the rack and the rear of the UPS.  
 
For more information about the REPO port, see "REPO port  (on page 11 )" . 
For information about verifying the  REPO connection, see " Verifying the REPO port connection  (on page 
42 )" .  
 
Connecting the ground bonding cable    
  NOTE:  UPS appearance might vary depending on the specific unit installed.  
  
Th e 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  24 
The ground bonding cable is not included.  
 
  
Connecting 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 grou nding 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 th e batteries. 
 
Connecting devices to the UPS     
						

							
 
Installation  25 
  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 IEC -to -IEC power 
cords included with the UPS.  
To provide additional receptacles:  
• Plug a PDU into the PDU output receptacle. The PDU output receptacl e is part of load segment 1 and 
can be turned off and on using power management software  (on page 51). 
• 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 vary 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.     
						

							
 
Installation  26 
  IMPORTANT:
  Charge the batteries for at least 24 hours before supplying backu p power to 
devices. The batteries charge to:  
•   80 percent of their capacity within 3 hours  
•   100 percent of their capacity within 48 hours  
  
 
S tarting power to the load  
Start power to the load by placing the UPS in Operate mode  (on page 38 ).   
  IMPORTANT:
  AC power must be available the first time the UPS is started.  
  
 
I nstalling the UPS as a tower  
Before installing the unit, review and adhere to all warnings provided in " Precautions (on page 13 )."  
Connecting the battery leads    
  WARNING:
  To prevent personal injury from electric shock or damage to the equipment, 
remove the battery lead labels, and verify that the ERM circuit breakers are in the Off 
position.  
  
   
						

							
 
Installation  27 
Rotating the logo badge  
Gently pull out the logo badge, rotate it 90 degrees, and then replace it in the bezel.  
  
Attaching the UPS front bezel  
  
Attaching the tower conversion stands    
  WARNING:
  To reduce t he risk of personal injury or damage to the equipment, the tower 
conversion stands must be properly attached when the unit is installed as a tower.  
   
						

							
 
Installation  28 
Using the preinstalled screws, attach the tower conversion stands to the unit.  
  
Continuing the installation 
To continue the UPS installation, follow the instructions starting with " Connecting the serial 
communications port  (on page 20 )."

Installation  30 
Connecting and securing the power cords  
  
Installing the ERM in a rack  
Before installing the unit, review and adhere to all warnings provided in " Precautions (on page 13 )."   
  WARNING:
  A risk of personal injury or damage to the equipment exists. Uneven loading of 
equipment in the rack might cause the rack to become u nstable. Install the heavier 
components first, and then continue to populate the rack from the bottom to the top.  
  
1.  Install the mounting rails  (" Installing the mounting rails " on page 14). 
2.  Install the mounti ng 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.
