will have two
lugs only.
After power wiring is complete, and when safe to do so, turn on the
branch-circuit disconnect switch. In some cases the blower may start.
Some DRY-O-TRON® units may have voltage monitors
that prevent operation in the event the branch circuit has voltage that
is too high, too low, has lost a phase, or has reversed phase
sequence.
If the green LED is not lit, confirm that the applied voltage is within
±10% of the nameplate voltage (NEMA MG-1), that all three phases
are present, and that the phase sequence is correct. (See
Diagnostics.) Correct as necessary.
Conduit seals are required.
See previous notes.

WARNING
Risk of electric shock. Can cause injury or death.
The unit controller does not disconnect electrical energy from the unit, even in the
OFF condition. Use only approved devices (e.g. locking safety switch), to disconnect,
lockout, and tagout all sources of electrical energy before working inside the unit
cabinet. Follow all applicable safety regulations.
