1.2—Using This Manual
This manual is intended to help with the process of safely receiving, unpacking, and installing Power Innovations
International, Inc.’s Q-LS Uninterruptible Power Quality™(UPQTM) systems. Refer to 2.1—Key Features to find an index
relating to the sections most helpful for correctly operating one particular feature on the Q-LS.
Read and understand this manual to make installing and operating the system as easy as possible.
1.3—Conventions Used in This Manual
1.3.1—Breaker Positions
Because some breakers on the front of the Q-LS Series share names with its subsystems or operation modes,
breakers and their positions will be identified using all caps. Additionally, the words ON and OFF are always
capitalized to stress which position is correct.
This convention exists to prevent the system components from becoming confused with names of breakers.
Skimming the words that are capitalized can also serve as a quick-reference method for learning the functions of
the breakers located on the front of the cabinet.
1.3.2—Cabinet vs. System
In this manual, the word cabinet refers to the actual Q-LS cabinet (or cabinets, for multi-cabinet systems). An
external battery cabinet (or cabinets, for more than one string of batteries) will be referred to as a battery cabinet
or battery unit.
The entire power quality system will be referred to as an Uninterruptible Power Quality (or UPQ) system, a Q-LS
or a Q-LS system. These terms do not refer to one cabinet or set of cabinets. They refer to the system and
everything that supplies power to it, including the battery cabinets, the cabinet that controls the system, and any
other cables or external controls.
1.3.3—Notes and Additional Advice
This manual will occasionally provide additional advice. When it is provided, this information will be enclosed by a
set of lines to separate it from the rest of the text, like this:
This advisory text is separated from the rest.
Some of the information can be very important, while other information may just be useful to know. To show the

Cautionary Statements
These offer advice that, if not followed, may harm equipment or indirectly cause physical hazards.
These symbols will be listed in order of importance.
1.4—Safety Warnings and Cautionary Statements
This section provides important information that you will need to remember to safely operate your system. Read it
carefully.
This manual provides very little information about maintaining the batteries. Such information is provided in a separate
manual for Q-LS trained and certified service personnel.
For ease in reading warnings and cautions, they have been divided into four sections, Manual Use, Installation and
Maintenance, Safe Transport and Storage, and Operation and Batteries.
1.4.1—Manual Use
Read this manual carefully before operating or troubleshooting the Q-LS and follow all
operating instructions. Failure to do so may cause physical harm.
Obey all warnings within this manual. Failure to do so may void the system warranty.

MNL129-4.8 Revision 3/14/2023 | 7
1.4.2—Installation and Maintenance
All maintenance must be performed by a service technician who has completed a training and certification course
on the Q-LS system offered through Power Innovations. During that training course, a separate manual is
provided to the service technician to use while maintaining the unit.
The Q-LS system must incorporate an earth ground.
The Q-LS Battery Module contains high voltage power that is potentially dangerous if not
handled properly. All repairs should be performed only by those who have completed Power
Innovations’ service-level training course.
For the warranty to apply, wiring, and setup verification for the Q-LS system must be commissioned
by personnel who have completed Power Innovations’ Q-LS training and certification course.
This unit contains no interior parts that can be serviced without qualified personnel. If troubleshooting
processes specified in this manual fail to solve a problem, qualified personnel must service the unit.
For the Q-LS to operate properly, it should be periodically inspected and cleaned. This routine
inspection and cleaning should be completed every 90–180 days.
1.4.3—Safe Transport and Storage
To avoid accidental worker injury, place this system in an area with limited access and ensure
that all cables are placed carefully.
The battery should be stored in a temperature-controlled indoor environment that is clean,
dry, and free of flammable liquids and corrosive substances such as hazardous gases.
The Q-LS system should be transported carefully so that the units are not damaged. Avoid dropping a
unit, tipping it upside down, or any other rough handling.
If the Q-LS system will be stored for long periods of time, the battery (batteries) should be charged by
the Q-LS once every 90 days to maintain optimal battery life or placed on Battery Keepers (available
from Power Innovations) and connected to utility power.
1.4.4—Operation and Batteries
If your battery model includes the slide-out tray option, the battery unit MUST be installed on a
solid surface. It should be bolted securely to the floor, if at all possible. Doing so will prevent
the cabinet from tipping and causing injury.
Always ensure that ONLY ONE battery drawer is open at any given time. Opening more than
one drawer of the cabinet at a time will cause the cabinet to become unbalanced and tip.
Use 10.5—Troubleshooting Tables in the Q-LS 10–160 Installation and Operation Manual to handle
any unusual situation that arises while operating the Q-LS system.
Retain the load within the Q-LS system rating guidelines to ensure that it functions well.
DO NOT insert any object into any of the ventilation holes or any other cabinet openings.

4—Preparing the Site
This chapter will explain how the site should be prepared to handle the system. Before installing the battery module,
consider the following placement considerations:
4.1—Facility Readiness
Before installing battery cabinets, examine the installation site carefully. Wiring modifications and other changes may
need to be made in preparation for attaching the Q-LS to the battery.
4.1.1—Electrician or Electrical Engineer Approval
It is important that an electrician or electrical engineer examine the site before the battery cabinets are installed.
The electrician or electrical engineer should:
•Verify and approve the facility’s wiring.
•Complete any necessary wiring preparations.
•Ensure that wiring to the battery and Q-LS complies with all local electrical codes.
•Install breakers to protect feed and output lines of the Q-LS.
•Verify and approve input and output cable sizes.
•Ensure that the system is grounded before it is made operational.
•Ensure that all outputs are properly referenced to ground.
ELECTRICAL WARNING
An electrician should be consulted about any external wiring decisions related to the system.
Any facility wiring that may interact with the system should be approved by an electrician
before installation.
WARNING
Inadequate cable size or oversized breakers may cause fire or damage. Decisions about
electrical cable sizes should be approved by a qualified professional before the system is
operated.

16 |
4.1.2—Personnel Access
Because the batteries store large amounts of power, personnel using the cabinets should know how to use them
correctly. To ensure that no unauthorized individuals attempt to operate the system:
•The cabinets should be placed in a location where access is limited.
•Personnel who operate the cabinets should be proficient in normal and emergency operational
procedures.
•Before operating the batteries or Q-LS, new personnel should be trained in their operation.
•The cabinet doors have locks, which can be used to prevent access if the cabinets are placed in a ready
access area.
4.1.3—Site Considerations
Ensure that the placement of the Q-LS system complies with all local building codes.
Consider the following when choosing where
the system will be installed:
•Select a site which has a floor strong
enough to bear the weight of the
Q-LS Battery Module (Table 1) and its
associated Q-LS cabinets. (See
MNL120 –Q-LS 10-160 kVA or
MNL123 –Q-LS 180-550 kVA
manual, as applicable.)
•Install the system on a level surface.
•Install the system in a location where
the walls, ceilings, and floors are
constructed from non-combustible
materials.
Caution
Do not place cabinets on uneven or unstable surfaces, especially without anchoring them. If any
cabinet is placed on an unstable surface or anchored insufficiently, the cabinet could tip and
cause injury.
