Voltage Jumper Blocks
To avoid permanently damaging the Group 5
controller, be certain that the voltage setting
matches the transfer switch system voltag e.
Eight jumper blocks on the Group 5 controller are
arranged in one of two patterns for the power supply to
meet the requirements of the 16 different voltage
inputs (shown in Table B on page A–2). These jumpers
are located on the front right side near the ribbon
cable. See Figures A–3 and A–4.
