Please read and save these instructions for future reference. Read
carefully before attempting to assemble, install, operate or maintain
the product described. Protect yourself and others by observing all
safety information. Failure to comply with instructions could result in
personal injury and/or property damage!
The EBSM Motor is an integrated industrial motor and speed control
that is simple and easy to install.
General Safety Information
This equipment contains voltages that may be as high as 1000 volts!
Electrical shock can cause serious or fatal injury. Only qualified per-
sonnel should attempt the start-up procedure or troubleshoot this
equipment.
This equipment may be connected to other machines that have rotat-
ing parts or parts that are driven by this equipment. Improper use can
cause serious or fatal injury. Only qualified personnel should attempt
the start-up procedure or troubleshoot this equipment.
WARNING:
Do not touch any circuit board, power device or electrical
connection before you first ensure that power has been disconnected.
Electrical shock can cause serious or fatal injury. Only qualified per-
sonnel should attempt the installation, operation and maintenance of
this equipment.
WARNING:
Disconnect all electrical power from the motor windings
and accessory devices before disassembly of the motor. Electrical
shock can cause serious or fatal injury.
WARNING:
Be sure the system is properly grounded before applying
power. Do not apply AC power before you ensure that all grounding
instructions have been followed. Electrical shock can cause serious or
fatal injury. National Electrical Code and Local codes must be carefully
followed.
WARNING:
Avoid extended exposure to machinery with high noise
levels. Be sure to wear ear protective devices to reduce harmful effects
to your hearing.
WARNING:
Surface temperatures of motor may reach temperatures
which can cause discomfort or injury to personnel accidentally coming
into contact with hot surfaces. When installing, protection should be
provided by the user to protect against accidental contact with hot
surfaces. Failure to observe this precaution could result in bodily injury.
WARNING:
Always disconnect, lock and tag power source before
installing or servicing. Failure to disconnect power source can result in
fire, shock or serious injury.
WARNING:
Motors that are to be used in flammable and/or explosive
atmospheres must display the CSA listed logo. Specific service condi-
tions for these motors are defined in NFPA 70 (NEC) Article 500.
WARNING:
Pacemaker danger – Magnetic and electromagnetic fields
in the vicinity of current carrying conductors and permanent magnet
motors can result in a serious health hazard to persons with cardiac
pacemakers, metal implants, and hearing aids. To avoid risk, stay
away from the area surrounding a permanent magnet motor.
WARNING:
Do not remove cover for at least five (5) minutes after AC
power is disconnected to allow capacitors to discharge. Dangerous
voltages are present inside the equipment. Electrical shock can cause
serious or fatal injury.
WARNING:
Motor circuit may have high voltage present whenever AC
power is applied, even when motor is not rotating. Electrical shock can
cause serious or fatal injury.
CAUTION:
Disconnect motor leads (T1, T2 and T3) from control be-
fore you perform a dielectric withstand (insulation) test on the motor.
Failure to disconnect motor from the control will result in extensive
damage to the control. The control is tested at the factory for high
voltage / leakage resistance as part of Underwriter Laboratory require-
ments.
CAUTION:
Suitable for use on a circuit capable of delivering not more
than 5000 RMS symmetrical short circuit amperes at rated voltage.
CAUTION:
Connection of power 115 or 230VAC power to “N” will
damage the unit.
1. Follow all local electrical and safety codes, as well as the National
Electrical Code (NEC) and the National Fire Protection Agency
(NFPA), where applicable. Follow the Canadian Electric Code
(CEC) in Canada.
2. The rotation of the fan wheel is critical. It must be free to rotate
without striking or rubbing any stationary objects.
3. Motor must be securely and adequately grounded.
4. Do not spin fan wheel faster than max cataloged fan RPM.
Adjustments to fan speed significantly effects motor load. If the
fan RPM is changed, the motor current should be checked to
make sure it is not exceeding the motor nameplate amps.
5. Do not allow the power or speed control cables to kink or come in
contact with oil, grease, hot surfaces or chemicals. If damaged,
discontinue use immediately and have cord replaced.
6. Verify that the power source is compatible with the equipment.
Branch protection and disconnect means must be provided if
required.
7. Never open access doors to a duct while the fan is running.
Features
Soft Start
All EBSM motors use soft start motor technology. They will reliably
start at any speed setting.
Overload
If the motor becomes overloaded, the control begins a countdown that
creates an “Overload Fault” when it ends.
Locked Rotor Protection
If a locked rotor condition occurs, the motor will automatically shut
itself down. Restart is attempted (up to 3 times). If the 3rd attempt
is unsuccessful, the motor will not attempt restart until power is
cycled (turned “Off” then “On”).
