Guidelines for Powering Auxiliary Conveyors
Before you can operate the auxiliary conveyors, you must ensure that adequate power is available.
• The auxiliary load and auxiliary unload augers or conveyors can be wired directly to the dryer.
• If an auxiliary motor is larger than recommended, it must be powered from a source outside the dryer
and must use a separate contactor and overload protection device for each motor. However, you can
operate the auxiliaries through the control panel.
• Refer to
Specifications for the Electrical Load on a Portable Dryer, page 45
for the maximum horse-
power and amps that can be wired to the dryer.
Specifications for the Electrical Load on a Portable Dryer
These charts provide information for you to ensure that the grain dryer and the auxiliary equipment are
supplied with adequate power.
It is recommended that you contact the local power company and have a representative verify the installa-
tion to make sure that the wiring is compatible with their system and adequate power is supplied to the
unit. The only equipment connected to the recommended service amps must be the grain dryer. You must
adhere to all national and local electrical regulations. (Refer to the National Electrical Code Standard hand-
book created by the National Fire Protection Association). A qualified electrician must make all electrical
wiring installations.
