The T
RIFECTA
system requires 20 Amperes of current at 110vac. The power should be run
into the control box through one of the extra conduit holes provided on the bottom of the
control box. For installation convenience, three gray terminals are provided on the bottom right
corner of the control panel for power supplies hook-up. As F
IGURE
3 indicates, the first of the
gray terminals (from the left)
1
is for the hot (black) wire of the power. The second terminal is
for the neutral (white) wire of the power and the last gray terminal is for the ground (green)
wire of the 110 vac-power supply. This is all of the power wiring that is needed. All other
power wiring has been completed at the factory.

It is important that care is taken to install the T
RIFECTA
system on an electrical power
circuit that is clean and protected. Circuits that are susceptible to noise and brownouts may
cause erratic behavior from the system. Care should also be taken to not install the system on a
circuit that regularly gets shut on and off to provide power to another piece of equipment
(lights, heaters, cooling systems etc.). It should be recognized that a PLC (computer) controls
the T
RIFECTA
system and a circuit similar to that, which would be used to power a personal
computer, should be used to power the T
RIFECTA
system. It is recommended that the
T
RIFECTA
system be powered by a dedicated circuit that is clean and protected to minimize
the chances or occurances of electrical noise, power surges or brown outs.
