ELECTRICAL SHOCK or UNIT DAMAGE HAZARD
Failure to follow this warning could result in personal
injury, death, and/or property damage.
Turn OFF electric power at fuse box or service panel
before making any electrical connections and ensure
a proper ground connection is made before connect-
ing line voltage.
All electrical work MUST conform with the requirements of local codes
and ordinances and the National Electrical Code NFPA 70 current
edition.
The low voltage transformer and the fan relay are standard on all
models and are prewired at the factory. Line voltage connections are
made to the wire pigtails in the unit.

NOTE
If increased structural strength is needed in the horizontal position,
use two field supplied connecting plates in place of the tabs on the
bottom of the blower.
OVERCURRENT PROTECTION
The power supply wiring to the unit MUST be provided with
overcurrent protection. Governing codes may require this to be fuses
ONLY or circuit breakers.
For blower cabinets MB08, MB12 and MB16 a 15 AMP circuit should
be used. For MB20 a 20 AMP circuit should be used.
LINE VOLTAGE CONNECTIONS
Line voltage wiring may be brought into the unit through the top
right−hand corner. A hole for a 1/2" or 3/4" (12.7mm or 19mm) conduit
fitting is provided.
Connect field wiring to the wire pigtails. All line voltage connections
must be made with copper wire.
Line Voltage Connection
1. Provide line voltage power supply (115V) from a separate
circuit.
2. Connect (115V) Hot to Black wire and Neutral to White wire.
GROUNDING CONNECTION
Use a copper conductor(s) from the ground lug to a grounded
connection in the electric service panel or a properly installed
grounding rod.
