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
personnel should attempt the start-up procedure or troubleshoot
this equipment.
This equipment may be connected to other machines that have
rotating 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 personnel 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 conditions 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 way 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
before 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 requirements.
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”).
