3.3 Chemical Hazards
Aspen battery materials are non-toxic and present no chemical hazards. The AHI electrolyte is
sodium-sulfate-based saltwater with a neutral pH. In the unlikely event that the electrolyte comes in
contact with eyes or skin, thoroughly wash it out with water. Electrolyte residue on the battery terminal
can be wiped away with a cloth. A collection pan under the battery stack or module is not needed as
the electrolyte will not leak during normal operation, and any leaked electrolyte will not damage battery
surfaces or equipment. Refer to the Safety Data Sheet (SDS) for more information.
3.4 Gas Emissions
The battery may emit trace amounts of gas H2, O2, CO2, and CO during normal operation. These gases
do not accumulate in hazardous quantities in typical installations when the batteries are installed and
operated in accordance with the guidelines of this document (see Section 5.2.3). The battery has fully
passed UL 1973 overcharge testing, an abuse test that includes monitoring for combustible vapor
concentrations. Overcharging the battery (outside of specified guidelines) will result in venting of
some incremental amounts of the gases listed above through the pressure relief valve.

International Safe Transit Association
4.2.1 Hazards
Aquion batteries are not hazardous and are not regulated as dangerous goods by the U.S.
Department of Transportation (DOT). They do not need special transportation services. Customers
shipping Aquion batteries Ex Works (EXW) should request the most recent Safety Data Sheet (SDS)
from Aquion. Aquion includes a hard copy of the most recent SDS with every shipment.
4.2.2 Requirements
Aspen batteries should be shipped in an upright position and should not be tipped for extended
periods. Communicate this restriction to the shipper prior to transport. The affixed Tip-N-Tell
indicators trip if the package experiences extreme tilt. See Section 5.3 for moving and tilting
restrictions.
4.3 Delivery Inspection
Immediately upon delivery, inspect all hard goods for signs of damage or tipping during transit before
signing for the delivery. Any of the following may indicate damage during transport:
+Damaged or torn packaging
+Tripped Drop-N-Tell indicator
+Scraped or punctured product components
+Tripped Tip-N-Tell indicator
+Leaking electrolyte (clear liquid)
If you find damage, document any signs of damage on the bill of lading before accepting the shipment.
Separately document and photograph all damage, and make a claim with the carrier as soon as
possible. Contact your distributor immediately.
Slight bulges or depressions in the cases of Aspen 24S or 48S batteries are normal. The battery cases
are intentionally flexible to accommodate compression of the electrode stack and normal variations in
internal pressure during operation. A depression or bulge of up to 10 mm in the sidewall of the battery
case is not unusual, especially in new batteries, and does not present an unsafe condition. If a bulge
projects more than 10 mm, do not place the battery in service, or remove it from service if already
commissioned, and contact Aquion Technical Support (see Section 10).

6 AQ-OP-00018_E.01 | 02.23.17
4.4 Disassembly Hazards
WARNING
Do NOT attempt to disassemble Aspen 48S or 24S batteries. Do NOT remove the nut on the
compression fixture on top of the battery.
Aspen 48S and 24S batteries have been compressed to optimize performance. Releasing this load
could result in poor battery performance, permanent damage to battery components, and/or injury.

5.2.3 Ventilation
Aquion batteries emit trace amounts of gas during normal cycle operation. Aquion recommends
installing the Aspen 48S in a non-sealed, ventilated area:
+For installations in locations that are frequently occupied (more than 8 hours of human occupation
per 24 hours), Aquion recommends continuous ventilation of 0.85 m3/hr (0.5 ft3/min) per
operational battery stack.
+For installations in locations that are infrequently occupied (less than 8 hours of human occupation
per 24 hours), Aquion recommends CO detection and periodic ventilation of 0.85 m3/hr (0.5 ft3/min)

8 AQ-OP-00018_E.01 | 02.23.17
per operational battery stack or in any instance when the measured CO concentration is greater
than the user’s defined environmental health and safety guidelines for CO.
Alternatively, in North America, IBC and/or NFPA 1 guidelines recommend that all battery installations
in enclosed spaces include ventilation equal to either six (6) air changes per hour or ventilation at
1 ft3/min per square foot of room size. In Europe and other locations, EN 50272 guidelines
recommend that batteries be installed in well-ventilated rooms where ventilation corresponds to
battery capacity and the exhaust air is discharged outside the building.
5.2.4 Humidity
Install Aspen batteries in clean, ordinary conditions protected from water exposure. Direct exposure
of Aspen batteries to water may cause shorting. The batteries may be installed in humid or coastal
regions with atmospheric salt.
5.2.5 Ambient Temperature
Aspen batteries must be operated in temperatures between -5°C and 40°C on a 24-hour average.
Operation above or below these limits will cause advanced degradation of the battery chemistry.
Aspen batteries must be stored in temperatures between -10°C and 40°C. Storage above or below
these limits may permanently damage the batteries.
5.3 Moving
5.3.1 48S, 24S
Use proper lifting procedures and personal protective equipment when moving Aspen batteries. The
Aspen 48S and 24S batteries have been designed to be moved using a lifting eye, included on each
pallet of batteries, screwed onto the threaded, metal tie-rod that runs vertically through the center of
the battery. No other component of the Aspen 48S and 24S is designed to support the battery’s
suspended weight. Use a crane, hoist, or similar device of appropriate load-bearing capacity to lift one
Aspen 48S or 24S battery at a time by the lifting eye.
NEVER LIFT ASPEN 48S OR 24S PRODUCTS BY THE TERMINALS OR ANY PART OTHER THAN AN
APPROPRIATELY RATED LIFTING EYE THREADED ONTO THE TIE-ROD AS THIS WILL VOID THE
WARRANTY AND MAY CAUSE DAMAGE TO THE PRODUCT AND/OR SIGNIFICANT INJURY.
Alternatively, use an appropriately sized hand truck to move Aspen 48S or
24S batteries. Position the battery on the hand truck so that the wiring faces
out, away from the upright frame of the hand truck. During movement to
the installation site and during installation, batteries may be tilted up to
forty-five (45) degrees for up to one hour. Before moving any Aspen 48S or
24S batteries, ensure that the travel path will not require tipping the battery
more than forty-five (45) degrees and that the installation location is level.
5.3.2 48M
The Aspen 48M battery must be transported and handled with appropriate precaution. The use of
forklift trucks and pallet jacks is recommended to move and position the battery. Before moving any
Aspen 48M battery, ensure that the travel path will not require tipping the battery more than fifteen
(15) degrees and that the installation location is level.

9 AQ-OP-00018_E.01 | 02.23.17
5.4 Placement
ATTENTION
Before restricting physical access to 48M or sensed 48S battery systems, such as in racking or
shipping containers,
1. Connect Aspen 48M fuses. This requires removing and replacing the top cover. See
Section 5.5.
2. Set up the batteries with the Aquion BMS-200. This requires physical connection of power
and communication cables. See the BMS-200 Installation & Operation Manual for
instructions.
Aspen batteries do not need any particular amount of clearance between other Aspen batteries or
other architectural features, so they can be arranged in tightly packed groups. Always follow local
codes for aisle and access requirements. Access and working spaces shall comply with all local codes.
However, when interpreting codes, note the following points:
+Access to the battery stack connections and lifting point for wiring and installation into the energy
storage system is available at the top of the batteries.
+When wired in parallel, Aspen batteries operate below 60 Vdc. Normal installation and operation of
Aspen batteries do not require access to the sides of the batteries, including the side with cable
harnesses.
+Aquion batteries do not normally require examination, adjustment, servicing, or maintenance while
energized.
Do not stack Aspen batteries on top of each other. Do not place other items on top of the batteries.
Aspen batteries are designed to be installed in an upright position (less than fifteen (15) degrees of tilt).
5.5 Fuse Connection Instructions – 48M
Each Aspen 48M battery ships with 12 installed, but disconnected, 20 A fuses, one for each
component Aspen 48S, located beneath the battery’s top cover. All 12 fuses must be connected for
the battery to operate. Connect the fuses before installing the battery in your system.
1. Remove the battery’s top cover.
a. Remove the four bolts from the front and
back of the battery’s top cover.

6.1.3 Contactor Control – 48M
A DC contactor (Gigavac GX11S) is installed on the positive (+) lead of each Aspen 48M battery. The
DC contactor must be powered by an external 24 V power supply. Aquion does not provide this power
supply.
A single 24 V power supply may be used to power the DC contactors of up to 16 Aspen 48M batteries
connected by appropriate power cables (see Section 6.1.2). The power supply, connected to the first
battery in the string, must be capable of supplying 100 mA to each battery in the system, plus at least
1 A of surge current. See Section 6.4 for cabling requirements.
The DC contactor operation can be easily integrated into a system-level emergency stop (ESTOP)
system to break down the series voltage to <59.5 Vdc.

WARNING
Do not disconnect any cables between cells within a 48S or 24S battery at any time during
installation, operation, or storage. Doing so voids the battery warranty and could lead to unsafe
operation of the batteries.
