Shipping and Receiving
Shipping
Rack assemblies are shipped in corrugated boxes. Battery cables, battery boots, terminal blocks, and
labels are also included in the shipment. Each pallet can support a maximum of two (2) units. Boxes
are shrink-wrapped to the pallet for added stability.
Batteries are shipped separately, and shrink wrapped to their pallet as well.
Receiving
Check for damages.
1. Upon receipt, inspect the boxes for obvious signs of rough handling.
2. Remove shrink wrap, open boxes, and conduct an internal inspection of the equipment.
Keep boxes on pallet for transportation to installation site.
3. Record any damages and call the carrier immediately to allow their personnel to conduct an
equipment inspection.
– DO NOT contact APC first—notify the carrier instead. Otherwise, APC may be unable to
assist in recovering the realized amount of the claim.
– All damage claims should be as specific as possible. Information pertaining to the shipment
should appear on the shipping label and related paperwork.
– BE SURE to request a copy of the carrier’s inspection report!
Check for discrepancies. Make certain the shipment has arrived in its entirety. Compare
information from the shipping label/parts list against what has been received. If any part is missing or
might have been damaged prior to shipping, contact APC immediately.

Placement
Positioning
The racks should ideally be positioned so that the batteries can easily be connected to the appropriate
breaker in the battery breaker box(es). The graphic below shows a typical UPS system, and how the
battery racks fit into the overall system.
If any or all of the racks are positioned apart from the battery breakers, sidecars
should be employed to achieve connectivity. Sidecars are discussed in detail in

Handling
The rack assemblies are relatively heavy (weighing 156 kg [344 lbs] each), so use a forklift or palletjack to transport boxes (on their pallets!) to the installation site. Upon arrival, re-open the boxes and
remove the assembly equipment. Organize the parts in an area as close as possible to the rack’s final
installation position.
If a rack must be moved or repositioned following assembly (and battery loading),
DO NOT lift (with forklift or pallet-jack) from the front! This could cause
batteries to slide off and might result in rack damage as well! Always lift from the

• There should be ample room for performing rack assembly, battery installation, maintenance,
and possible battery replacement.
• Aisle spacing should be in accordance with applicable code requirements.
• Racks should be set on a firm and reasonably level surface. Shimming up to a maximum of
6 mm [0.25 in.] may be used to level corner posts both front-to-ba ck and side-to-side.
• Consider all requirements and restrictions with respect to floor loading.
• Batteries must remain in a climate-controlled environment having a temperature range of 22° to
25° C [72° to 77° F] and a relative humidity of 0% to 95%, non-condensing.
• Batteries should not be exposed to excessive moisture, construction dirt, corrosive elements,
and other contaminants.

Appendix C: Employing Sidecars
Sidecar overview
Battery racks can be situated in one or more locations separate and apart from the battery breakers. In
these instances, a sidecar should be employed at each separated location to prevent distance from
compromising electrical connectivity. Sidecars permit use of larger output cables to alleviate the
problem of power degradation.
Separated sidecars must be grouped in multiples of two (2, 4, 6, 8, etc.).
Note
Sidecar enclosures measure approximately 585 mm (W) x 914 mm (D) x 2032 mm (H) [2 3” x 36” x
80”] and weigh approximately 227 kg [500 lb].
Each sidecar contains four distinct U-shaped busbar sets (with landing holes) for connecting a) inputs
FROM the battery racks, and b) outputs TO the battery breakers. Each U-shaped set consists of two
vertical input bars and one horizontal output bar. The horizontal bars are “staggered” (in terms of
height and depth) to avoid congestion when connecting the larger output cables to them. The sets are
designated as follows from front-to-back: BAT 1+, BAT 1-, BAT 2+, and BAT 2-.

Appendix C: Employing Sidecars
Positioning and accessing the sidecar
The sidecar is typically positioned alongside one of the separated racks it supports, and ideally should
be positioned closest (of all units in the group) to the battery breakers.
Sidecars offer full front access to all of their internal components. The sidecar’s front door is secured
by a key lock (keys are included). Open the front door by first releasing and then twisting the latch a
quarter-turn to the left. The door can be removed completely by releasing its two hinge pins.
While the sidecar offers both top and bottom cable entry, TOP is recommended. A torx-head
screwdriver is needed to remove the four (4) corner screws securing the top plate to the enclosure, or
(if using bottom entry) the six (6) perimeter screws securing the bottom plate.

APC Warranty on Batteries
APC warrants that its supplied High-Rate series of Valve Regulated Lead Acid batteries will be free
of defects in material and workmanship for a period of one (1) year from date of shipment. This
amounts to the same basic warranty that is being offered by the leading battery manufacturers.
Additional coverage can be procured through purchase of an extended warranty. Call your APC
representative for information concerning the various types of extended warranties available.
Battery functionality is typically impacted by age and environmental conditions, and therefore certain
requirements must be met by the end-user pursuant to this warranty. Failure to adhere to the
following conditions may put the warranty at risk.
APC-supplied batteries must always be kept in a climate-controlled environment, and should be recharged at a minimum of every three (3) months in situations where no automatic charging takes
place. The battery environment must be free of excessive moisture, construction dirt, corrosive
elements, or other contaminants. The temperature range must be maintained at 22° to 25° C / 72° to
77° F for batteries in an operating environment, and 0° to 25° C / 32° to 77° F for batteries in a
storage environment. The relative humidity must be maintained at 0 to 95%, non-condensing.
APC must be notified immediately upon suspicion of possible battery defects, and be subsequently
given authority to inspect any sites containing potentially defective batteries. If APC determines its
supplied batteries to be defective due to material or workmanship, APC will repair or replace those
batteries at its option, F.O.B. factory, without charge. Should battery repair or replacement occur as a
result of this warranty, the warranty period will be pro-rated accordingly.
APC shall not be liable under this warranty if its testing and examination disclose that the alleged
defect in the product does not exist or was caused by the purchaser’s, or any third person’s misuse,
negligence, improper installation or testing, unauthorized attempts to repair of modify, or any other
cause beyond the range of the intended use, or by accident, fire, lightning, or other hazard.
There are no warranties, express or implied, by operation of law or otherwise, of products sold or
furnished under this agreement or in connection herewith. APC disclaims all implied warranties of
merchantability, satisfaction, and fitness for a particular purpose. APC’s express warranties will not
be enlarged, diminished, or affected by and no obligation of liability will arise out of, APC’s
rendering of technical or other advice or service in connection with the products. The foregoing
warranties and remedies are exclusive and in lieu of all other warranties and remedies. APC’s
warranties run only to purchaser and are not extended to any third parties.
