that when fuses are being replaced only fuses of the specified type
and of the correct are used.
4.4.4. This equipment conforms to Class 1 safety standards, which means
that the appliance must be earthed and requires to be powered
from an earthed supply.
4.5. Grounding the charger
4.5.1. Grounding the charger
4.5.2.
Connect ground wire to the proper terminal usually
marked with either of the two symbols to the right.
4.5.3. DANGER: FAILURE TO GROUND THE CHARGER COULD LEAD TO
FATAL ELECTRIC SHOCK. Follow National Electric Code for ground
wire sizing.
4.6. DC connector polarity
4.6.1.
DC plug polarity
4.6.2.
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.

Note: DC cables of the charger emit low power magnetic fields in their
surroundings (<5cm). Even if emissions are below the standard limits,
people bearing medical implants should avoid operating close to the
charger during recharge.
3.13. Do not
expose the charger to moisture. Operating conditions should be
32ºF (0ºC) to 113ºF (45ºC); 0 to 70% relative humidity.
3.14. Do not
operate the charger if it has been dropped, received a sharp impact,
or otherwise damaged in any way.
3.15.
For continued protection and to reduce the risk of fire, install chargers
on a non-combustible surface.
3.16.
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.
3.17.
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.
3.18.
Contact one of the company’s trained technicians if any problem is
encountered when putting the charger into operation. It is only designed to
recharge Industrial Motive Power lead acid and EnerSys
®
NexSys
®
batteries
on industrial premises. When the equipment becomes obsolete, the
casings and the other internal components can be disposed of by specialist
companies. Local legislation takes precedence over any instructions in this
document and must be scrupulously observed (WEEE 2002/96 EC).
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 72 cm 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 31 cm. If wall mounted, make sure that the surface is free
of vibrations and the charger is mounted in a vertical position; if
floor mounted, make sure that the surfaces are free of vibration,
water, humidity. You must avoid areas where the chargers may be
splashed with water.
4.2.2.
The charger must be held by 2 or 4 fixings suitable for the type
of support. The drilling pattern varies according to the model of
charger (please refer to the technical data sheet).
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 local country standards
and laws 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.
4.3.3. To the mains supply:
You may only connect to the 1-phase 230Vac
or 3-phase 400Vac mains supply (depending on the type of the
charger) by means of a standard socket and an appropriate circuit
breaker (not supplied). The current consumption is shown on the
charger’s information plate.
4.3.4. To the mains supply:
You may only connect to the 1-phase 230Vac
or 3-phase 400Vac mains supply (depending on the type of the
charger) by means of a standard socket and an appropriate circuit
breaker (not supplied). The current consumption is shown on the
charger’s information plate.
4.3.5.
Connection to battery: The charger must be connected to the battery
by the cables supplied:
- The RED cable: to the battery’s POSITIVE terminal.
- The BLACK cable: to the battery’s NEGATIVE terminal.
4.4. AC circuit protection
4.4.1.
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
4.4.2. CAUTION: Risk of Fire/Electrick shock. Use only on circuits provided
with branch circuit protection in accordance with lows and
standards.
4.4.3. The prevailing safety regulations must be observed. The system
protection installed on the power supply to the charger must
conform to the charger’s electrical characteristics. The installation of
a suitable circuit breaker is recommended. It is imperative to ensure
