Installation
Electrical Connections
To prevent failure of the charger, make sure it is
connected to the correct line voltage. Follow your
local country standards and laws in making these
connections.
Make sure the power source is OFF
WARNING
and the battery is disconnected before connecting
the input power to the terminals of the charger.
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.
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.
AC Circuit Protection
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.
Risk of Fire/Electric Shock. Use only
CAUTION
on circuits provided with branch circuit protection
in accordance with laws and standards.
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 that when fuses are being
replaced, only fuses of the specified type and of
the correct size are used.
This equipment conforms to Class 1 safety
standards, which means that the appliance must
be earthed and must be powered from an earthed
supply.
Grounding the Charger
Connect ground wire to the proper terminal, usually
marked with either of the two symbols below.

FAILURE TO GROUND THE CHARGER
DANGER
COULD LEAD TO FATAL ELECTRIC SHOCK. Follow
National Electric Code for ground wire sizing.
DC Connector Polarity
DC plug polarity
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 with
medical implants should avoid being near the charger
during recharge.
