2.1.2 INSTALLATION GUIDELINES (CONTROL PANEL & IDLER)
Steps to install the control panel and idler:
a. Mount enclosure on a secure wall or on the idler (idler mount
models only.) Attach conduit fittings for single phase input line, 3-

b. Pull electrical lines into the enclosure. Be sure to pull enough wire
for your load to reach the two terminals on the left side (L1 & L2)
plus the terminal on the right side (T3) of the phase converter
controls. Run the ground lines with each circuit.
c. Connect the lines to the idler/generator to the terminals marked A,
B and C.
d. Connect the three phase output lines to the terminals marked
L1/T1, L2/T2, and T3.
e. Connect the single phase input lines to the terminals marked L1
