3.Electrical Service
The electrical power is connected to the dryer at the high voltage section of the control cabinet. On the MLS-460 dryer, this section is located at the bottom left of the main electrical enclosure.
The MLS-460 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 MLS-460 WITH SPRINKLER OPTION WILL NOT OPERATE WITHOUTAN 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.
