3.8. Only factory-qualified personnel should install, set up and service
this equipment. De-energize all AC and DC power connections before
servicing the charger.
3.9. The charger is not for outdoor use.
3.10. Do not expose the charger to moisture. Operating conditions should be
32ºF (0ºC) to 113ºF (45ºC); 0 to 70% relative humidity.
3.11. Do not operate the charger if it has been dropped, received a sharp
impact, or otherwise damaged in any way.
3.12. For continued protection and to reduce the risk of fire, install chargers
on a non-combustible surface.
3.13. For NexSys
®
iON batteries, use only EnerSys
®
battery packs that include
the battery management system and all necessary protection for the
battery pack integral to the pack.
3.14. The DC cables of the charger emit low power magnetic fields in their
surroundings (<5cm). People with medical implant devices should avoid
being near charger while charging.
4.1. Location
4.1.1. For safe operation, choose a location which is free of excess
moisture, dust, combustible material, and corrosive fumes. Also,
avoid high temperature (above 113ºF (45ºC)) or potential liquid
spill on the charger.
4.1.2. Do not obstruct the openings in the charger for air ventilation.
4.1.3. Follow charger warning label when mounting on or over a
combustible surface.
4.1.4. It is recommended to mount the charger at least 28 inches radial
distance away from the closest top edge of the battery.
4.2. Cabinet mounting
4.2.1. The charger must be mounted on a wall, stand, shelf or floor in
a vertical position. The minimum distance between two chargers
must be 12 inches.
4.2.2. The charger must be installed with four 5/15-inch bolts or with
the bracket supplied. Charger should be permanently fastened in
place.
4.2.3. For shelf mounting, part number 159-6LA22723 is required – two
per charger.
4.3. Electrical connections
4.3.1. To prevent failure of the charger, make sure it is connected to the
correct line voltage. Follow your local and National Electric Code
(NEC) in making these connections.
4.3.2. WARNING: Make sure the power source is OFF and the battery is
disconnected before connecting the input power to the terminals
of the charger.
4.4. Connecting input power
4.4.1. Connect the input power to the appropriate terminals and apply
appropriate torque as follow:

4.4.2. Three phase chargers are not phase rotation sensitive and work
with a grounded Delta or Wye electrical service configuration.
4.5. AC circuit protection
4.5.1. The user must provide suitable branch circuit protection and a
disconnect method from the AC power supply to the charger to
allow for safe servicing.
4.5.2. CAUTION: Risk of Fire. Use only on circuits provided with branch
circuit protection in accordance with the Breaker/Fuse Chart table
in this manual, and the National Electrical Code, NFPA 70.

4.6. Grounding the charger
4.6.1. Connect ground wire to terminal marked with
either of the two symbols to the right and apply
same torque value per the table in section 4.4.1.
4.6.2. DANGER: FAILURE TO GROUND THE CHARGER COULD LEAD TO
FATAL ELECTRIC SHOCK. Follow National Electric Code for ground
wire sizing.
4.7. DC connector polarity
4.7.1. DC plug polarity
4.7.2. The charging cables are connected to the DC output of the charger:
the red charging cable (POS) is connected to the positive busbar of
the charger, and the black charging cable (NEG) is connected to the
negative busbar of the charger. The output polarity of the charger must
be observed when connecting to the battery. Improper connection will
open the DC fuses in the power modules.
