IMPORTANT SAFETY INSTRUCTIONS
General Safety
DANGER! YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to hazards. These procedures should be
performed by qualified technicians familiar with the hazards associated with this type of equipment.
These hazards may include shock, energy, and/or burns. To avoid these hazards:
a) The tasks should be performed in the order indicated.
b) Remove watches, rings, and other metal objects.
c) Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage
or the expected voltage is present. Check for voltage with both AC and DC voltmeters prior to
making contact.
d) Wear eye protection.
e) Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed.
Voltages
Battery Voltage
DANGER! This system has a battery source connected to it. Although the DC voltage is not
hazardously high, the rectifiers and/or battery can deliver large amounts of current. Exercise extreme
caution not to inadvertently contact or have any tool inadvertently contact an output terminal or battery
terminal or exposed wire connected to an output terminal or battery terminal. NEVER allow a metal
object, such as a tool, to contact more than one termination or battery terminal at a time, or to
simultaneously contact a termination or battery terminal and a grounded object. Even a momentary
short circuit can cause sparking, explosion, and injury.

Battery
Refer to the battery manufacturer documentation for specific battery safety instructions. The following are
general guidelines.
WARNING! Correct polarity must be observed when connecting battery leads.
WARNING! Special safety precautions are required for procedures involving handling, installing, and
servicing batteries. Observe all battery safety precautions in this manual and in the battery instruction
manual. These precautions should be followed implicitly at all times.
WARNING! A battery can present a risk of electrical shock and high short circuit current. Servicing of
batteries should be performed or supervised only by properly trained and qualified personnel
knowledgeable about batteries and the required precautions.
The following precautions should be observed when working on batteries:
• Remove watches, rings, and other metal objects.
• Eye protection should be worn to prevent injury from accidental electrical arcs.
• Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed. Ensure that wrenches with more than one working end have only one
end exposed.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Risk of explosion if battery is replaced with an incorrect type or if polarity is reversed.
Recommended to replace batteries with the same manufacturer and type, or equivalent.
• Dispose of used batteries according to the instructions provided with the batteries. Do not dispose
of batteries in a fire. They may explode.
• ALWAYS FOLLOW THE BATTERY MANUFACTURER’S RECOMMENDATIONS AND SAFETY
INSTRUCTIONS.
DANGER! This equipment may be used in conjunction with lead-acid batteries. Working near lead-acid
batteries is dangerous!
In addition to the hazard of electric shock, gas produced by batteries can be explosive and sulfuric acid
can cause severe burns.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes, and is toxic.
• Batteries contain sulfuric acid.
• Batteries generate explosive gases during normal operation. Systems containing batteries should
never be installed in an airtight room or space. Only install in a ventilated environment.
• Batteries are an energy source that can produce high amounts of electrical current.
Vertiv | NetSure Battery Rack System (+24 VDC) Installation Manual (Section 6044) | Rev. E

FOR THESE REASONS, IT IS OF CRITICAL IMPORTANCE THAT YOU READ THESE INSTRUCTIONS
AND FOLLOW THEM EXACTLY.
WHEN WORKING WITH LEAD-ACID BATTERIES:
• Follow the recommended PPE requirements per the SDS for the battery to be used.
• If battery acid enters your eye, immediately flush your eye with running cold water for at least 15
minutes. Get medical attention immediately.
• If battery acid contacts skin or clothing, wash immediately with soap and water.
ALERT! Performing maintenance and/or troubleshooting procedures may interrupt power to the loads,
if battery reserve is not sufficient.
Personal Protective Equipment (PPE)
DANGER! ARC FLASH AND SHOCK HAZARD.
Appropriate PPE and tools required when working on this equipment. An appropriate flash protection
boundary analysis should be done determine the “hazard/risk” category, and to select proper PPE.
This product is intended only for installation in a Restricted Access Location.
Only authorized and properly trained personnel should be allowed to install, inspect, operate, or maintain
the equipment.
Do not work on LIVE parts. If required to work or operate live parts, obtain appropriate Energized Work
Permits as required by the local authority, per NFPA 70E “Standard for Electrical Safety in the
Workplace”.
Maintenance and Replacement Procedures
CAUTION! When performing any step in procedures that requires removal or installation of hardware,
use caution to ensure no hardware is dropped and left inside the unit; otherwise service interruption or
equipment damage may occur.
NOTE!
When performing any step in procedures that requires removal of existing hardware, retain all
hardware for use in subsequent steps, unless otherwise directed.

Battery Connections to Respective Power System
Lug-terminated battery conductors must extend from the termination busbars located at the top of the Battery
Rack System to the respective power system’s battery busbar and battery return busbar. Refer to the
documentation provided with the power system for connections to the power system. The termination busbars
in the Battery Rack System are provided with 3/8 16 captive fasteners for installation of customer provided twohole lugs with 1-inch centers. Customer must provide lug mounting bolts, washers, and additional hardware.
Refer to Figure 5.
Procedure
1. Remove front and rear protective covers.
ALERT! Observe correct polarity when making connections. Reversing polarity may result in damage to
batteries, power system, and loads.
2. Connect the negative (-) conductors to the GROUND/RETURN termination busbar.
3. Connect the positive (+) conductors to the +24V Battery (Supply) termination busbar.
4. Torque all connections. Recommended torque is 180 in-lbs when using 3/8” bolts with a Belleville lock
washer and 300 in-lbs when using 3/8” bolts with a standard flat washer and lock washer.
5. When connections are complete and verified, reinstall front and rear protective covers.
