ACS offers a complete line of automatic loading equipment to automatically load the drying

3-4 Making Electrical Connections
; Fulfill all national, state, and local safety and electrical code
requirements.
; Only a qualified electrician should make electrical connections.
; Make sure all electrical connections are tight.
Caution! Disconnect the electricity before maintenance or service!
; If the dryer is installed with a power cord that can be unplugged, unplug
it. If the dryer is permanently wired to a power main, a fused power
disconnect must be installed to allow the disconnect to be locked in the
OFF position. The above should be performed in accordance with
applicable safety regulations.
Power Drop
Refer to the serial number plate for voltage and phase requirements. The power drop must
include a ground wire. Installation must conform to NEC, CSA, and/or other electrical safety
standards in force at the installation site.
Blower Motor Rotation
Most ACS dryers require a three (3)-phase power drop. When the drop is wired correctly, air
flows out of the delivery outlet. Incorrect wiring of the three (3) power leads will cause
backward rotation of the blower.
Important!
Make sure that the fill cover is left on the drying
hopper or air diffuser/air trap assembly at all times to prevent
contamination of the material and ensure proper drying.
Important!
If the blower is turning backwards, do not reverse the wires at the
motor starters. Instead, reverse the two (2) wires at the wire drop.
