AC INPUT CONNECTION
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 TERMINAL BLOCKS FOR AC INPUT CABLE,
that are located on the right side of the internal panel, just under the AC input contactor (see
picture on the next page).
Make sure to tighten the terminal block screws with the right torque, and pull each wire
separately in order to verify that they are mounted properly.
AC INPUT VOLTAGE SETTINGS
• With reference to the pictures in the next page, find the POWER TRANSFORMER TAPS
and the label with the list of the 5 NOMINAL voltages available, that are located on the
left side of the internal panel.
SR2400 SR2403 SR4800 SR6000
1 1x 250 VAC 3x 250 VAC 3x 500 VAC 3x 620 VAC
2 1x 240 VAC 3x 240 VAC 3x 490 VAC 3x 610 VAC
3 1x 224 VAC 3x 224 VAC 3x 480 VAC 3x 600 VAC
4 1x 208 VAC 3x 208 VAC 3x 460 VAC 3x 575 VAC
5 1x 200 VAC 3x 200 VAC 3x 440 VAC 3x 550 VAC
• 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 5 NOMINAL voltage values is closest to the REAL measured value.
Example 1: for a charger ES2400 (singlephase) if the measured voltage is 212 VAC,
the transformer should be connected to the tap number 4, that
corresponds to 208 VAC.
Example 2: for a charger ES6000 (threephase) if the measured voltage is 608 VAC,
the transformer should be connected to the tap number 2, that
corresponds to 610 VAC
• For the singlephase units (ES2400), the wires to be moved are the TWO that are
connected to the AC contactor, marked with the letter “A”.
