Important Safety Instructions

Safety Admonishments Definitions

Definitions of the safety admonishments used in this document are listed under “Admonishments Used in this Document” on page iv.

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

AC Input Voltages

DANGER! This system operates from AC input voltage capable of producing fatal electrical shock. AC input power must be

completely disconnected from the branch circuits wiring used to provide power to the system before any AC electrical

connections are made. Follow local lockout/tagout procedures to ensure upstream branch circuit breakers remain de-

energized during installation. DO NOT apply AC input power to the system until all electrical connections have been

completed and checked.

AC Output Voltages

DANGER! This system produces AC output voltage capable of producing fatal electrical shock.

AC output voltage is present even if only the DC input is connected!

DANGER! Follow local lockout/tagout procedures to ensure AC branch circuit protection devices remain de-energized

during installation at loads, as required.

DC Input Voltages

DANGER! This system operates from DC input voltage. Although the DC voltage is not hazardously high, the DC input

power can deliver large amounts of current. Exercise extreme caution not to inadvertently contact or have any tool

inadvertently contact a DC input terminal or exposed wire connected to a DC input terminal. NEVER allow a metal object,

such as a tool, to contact more than one DC input terminal at a time, or to simultaneously contact a DC input terminal and a

grounded object. Even a momentary short circuit can cause sparking, explosion, and injury.

Vertiv™ NetSure™ Inverter System Installation Manual

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 to determine the “hazard/risk” category, and to select proper PPE.

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”.

Hazardous Voltage

DANGER! HAZARD OF ELECTRICAL SHOCK.

More than one disconnect may be required to de-energize the system before servicing. The inverter system is not supplied

with internal input voltage disconnect devices. It is a dual input power supply. Even if the main AC power to the inverter

system has been disconnected, potential harm still exists from the inverters taking power from the DC input power source.

Handling Equipment Containing Static Sensitive Components

ALERT! Installation or removal of equipment containing static sensitive components requires careful handling. Before

handling any equipment containing static sensitive components, read and follow the instructions under “Static Warning” on

page vii.

Maintenance and Replacement Procedures

CAUTION! When performing any step in the 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 the procedures that requires removal of existing hardware, retain all hardware for use in

subsequent steps, unless otherwise directed.

This equipment contains static sensitive components. The warnings listed below must be observed to prevent damage to

these components. Disregarding any of these warnings may result in personal injury or damage to the equipment.

1. Strictly adhere to the procedures provided in this document.

2. Before touching any equipment containing static sensitive components, discharge all static electricity from yourself by

wearing a wrist strap grounded through a one megohm resistor. Some wrist straps have a built-in one megohm resistor;

no external resistor is necessary. Read and follow wrist strap manufacturer’s instructions outlining use of a specific wrist

strap.

3. Do not touch traces or components on equipment containing static sensitive components. Handle equipment

containing static sensitive components only by the edges that do not have connector pads.

4. After removing equipment containing static sensitive components, place the equipment only on static dissipative

surfaces such as conductive foam or ESD bag. Do not use ordinary Styrofoam or ordinary plastic.

5. Store and ship equipment containing static sensitive components only in static shielding containers.

6. If necessary to repair equipment containing static sensitive components, wear an appropriately grounded wrist strap,

work on a conductive surface, use a grounded soldering iron, and use grounded test equipment.
