Storage / Refresh
Continued
5. Whenever a refresh charge is required, it’s important that all
batteries to be installed in the same series string receive a
charge at the same time to ensure continuity once placed in
their intended application.
6. Each cell shall be charged for 24 hours at a constant voltage
equal to 2.40 volts per cell. To ensure the cells are fully
charged within 24hrs, the charger used for this refresh charge
must have the capacity to provide at least the minimum
charge current specification and not exceed the maximum
charge current for the given cell type (model), as called out
in Appendix D.
7. All requested information on “Refresh Record Form” in
Appendix A should be completed for each refresh charge.
8. Cells shall not be stored beyond 12 months. Storing beyond
12 months will affect warranty.
9. If the storage / refresh requirements cannot be met, contact
East Penn Reserve Power’s Product Support group for
alternate instructions.
INSTALLATION
General
Caution should be taken when installing cells to ensure no
damage occurs. Cells shall not be dropped, slid, or placed on
rough or uneven surfaces such as tray lips or grated flooring.
Mishandling of cells could result in equipment damage or
human injury. East Penn will not be liable for damage or injury
as a result of mishandling or misuse of the product.
Grounding
When grounding the battery string, proper techniques should
be applied per electrical standards, such as NEC and/or local
codes. Two 0.201 diameter x 0.750 center holes are provided in
back of each module to accept a # 6 x 0.750 center compression
grounding lug. The holes must be tapped for a 1/4-20UNC thread
and paint must be removed for a proper grounding pad location.*
*Note: Battery string and/or stack to stack grounding,
if required, is the installer’s responsibility.
Electric Code for Maintenance Access
Refer to ANSI/NFPA-70 National Electric Code for access and
working space requirements around the battery. A minimum of
36” aisle space is recommended in front of the battery system
for service and inspection.
Hardware Torque Requirements
System Installation
System Shipment
Battery string will be received per drawing below.
Non-Interlock Module Installation
Assemble battery string per the following details.
All parts should be verified against packaging list. Report any
missing parts.
1.
Remove floor-mounting base support from the top of the
modules. Base(s) are wire tied to module assembly.
2.
Position base(s). Consult included battery string layout diagram
for required base layout. If it can not be located, contact East
Penn Mfg. for a copy. Refer to your delivery number, located on
the packing slip. This will aid in obtaining the proper drawing.
3.
Bases are required to be level prior to installing modules.
