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.
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 laws
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
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.
