CONNECTION OF THE AC INPUT:
The charger must be connected to the AC input using an adequate cable and plug, with disconnect switch and fuses.
The AC input wires have to be connected to the AC INPUT TERMINAL BLOCK, that is located on the internal panel, just
under the AC input contactor. Make sure to tighten the terminal block screws with the proper torque, and pull each wire
separately in order to verify that they are mounted properly.
AC INPUT VOLTAGE SELECTION 208/240 OR 480 VAC:
The three-phase models may be configured for 208/240 VAC or 480 VAC nominal input voltage.
This selection can be done using the AC INPUT VOLTAGE PRESET BOARD 208-240 or 480 VAC, that is located at the center
of the internal panel, near the terminal blocks for the AC input wires. In addition, it’s necessary to adjust the AC input
connection of the AUXILIARY TRANSFORMER to the proper AC input voltage.
• Disconnect the charger from main supply and battery.
• Remove the plastic protection over the AC INPUT VOLTAGE PRESET BOARD
• Remove the three metal bars.
• Place the metal bars in the required position, with ref to the following pictures.
• Tighten the nuts with the proper torque.
• Apply the plastic protection.
• Connect the charger to main supply.

>>>ATTENTION!<<<
The proper setting of the power transformer taps is very important for the correct operation of the BLACK
Diamond chargers.
The POWER TRANSFORMER TAPS
and the label with the list of the NOMINAL voltages that are
available are located on the internal panel, in a central position. Depending on the charger model, the number of
available taps may range from 3 to 5.
The following table is referred to the 3 taps version.
• Using an adequate AC-voltmeter, measure the value of the REAL AC input voltage available at the mounting location of
the charger.
• Identify which of the NOMINAL voltage values is closest to the REAL measured value.
• For the singlephase units, the wires to be moved are the TWO that are connected to the AC contactor, marked with the
letter “A”.
• For the threephase units, the wires to be moved are the THREE that are connected to the AC contactors, marked with
the letters “A”, “B” and “C”.
