3. Electrical Service
The electrical power is connected the dryer at the high voltage section of the control cabinet. On the
ADS-464 dryer, this section is located at the bottom left of the main electrical enclosure.
The ADS-464 dryer, with sprinkler option, must be supplied with two (2) independent input power lines.
One is 3-phase (3ø) electric service that feeds the dryer itself, and the other is single-phase (1ø) electric
service that feeds the safety sprinkler system. Both input lines must be independent of each other and
individually protected by their own individual fused disconnect.
IMPORTANT: THE ADS-464 WILL NOT OPERATE WITHOUT AN INDEPENDENT
POWER SOURCE FED TO THE SAFETY SPRINKLER SYSTEM.
Feed the electrical service cables to the dryer using the pre-punched knockouts at the bottom section of the
electrical cabinet right wall.
Connect the ground wires directly to the ground lug located at the same approximate area.
Before turning power on to the dryer, measure the supply voltage to ensure that it matches the dryer’s
specified input voltage. This input voltage is marked on the aluminum data plate located on the inner right
wall of the electrical cabinet.
IMPORTANT: For proper sprinkler and dryer operation, sprinkler must be powered by a “separate
or dedicated” single-phase (1ø) multi-wire branch circuit at dryer’s nameplate voltage.
