4.5.3 - AVAILABLE OUTPUT VOLTAGES: HARDWARE MODIFICATIONS
The following output voltages are available: 120, 208, 220, 230, 240, 277 Vac. An insertion bridge is placed between
terminals 2 and 3. An extra insertion bridge was delivered with the unit (in a plastic bag) to enable other output voltages.
4.5.3.1 – OUTPUT VOLTAGE 277VAC
The off-factory setting is 277VAC; make sure the following steps are implemented:
1. An insertion bridge is placed between terminals 2 and 3.
2. The output tap is set at 277VAC: Please refer to fig.11 and 11a and check the following.
White wire W is connected to faston 67 (connect) on Printed Circuit Board (PCB) part 1113-C
Brown wire F is connected to faston 65 (park) on PCB part 1113-C
Yellow wire L is connected to faston 66 (park) on PCB part 1113-C
3. Connect the output wires to the terminals 1 (L1) and 4 (L2) and ground wire to terminal 5. Ground connection is
essential! See figure 11b.
4. Return to either section 4.5.1.1 step 5 or section 4.5.1.2 step 5. Pay special attention to step 11 in these sections,
i.e. do not forget to modify the display software as described in section 4.5.4.
