PRECAUTIONS:

 

WARNING:

Do not touch any circuit board, power device or electrical

 

connection before you first ensure that power has been

 

disconnected and there is no high voltage present from this

 

equipment or other equipment to which it is connected.

 

Electrical shock can cause serious or fatal injury.

WARNING:

Be sure that you are completely familiar with the safe operation

 

of this equipment. This equipment may be connected to other

 

machines that have rotating parts or parts that are controlled by

 

this equipment. Improper use can cause serious or fatal injury.

WARNING:

Be sure all wiring complies with the National Electrical Code and

 

all regional and local codes or CE Compliance. Improper wiring

 

may cause a hazardous condition.

WARNING:

Be sure the system is properly grounded before applying power.

 

Do not apply AC power before you ensure that grounds are

 

connected. Electrical shock can cause serious or fatal injury.

WARNING:

Do not remove cover for at least five (5) minutes after AC power

 

is disconnected to allow capacitors to discharge. Electrical

 

shock can cause serious or fatal injury.

WARNING:

Improper operation of control may cause violent motion of the

 

motor and driven equipment. Be certain that unexpected

 

movement will not cause injury to personnel or damage to

 

equipment. Peak torque of several times the rated motor torque

 

can occur during control failure.

WARNING:

Motor circuit may have high voltage present whenever AC power

 

is applied, even when motor is not moving. Electrical shock can

 

cause serious or fatal injury.

WARNING:

If a motor is driven mechanically, it may generate hazardous

 

voltages that are conducted to its power input terminals. The

 

enclosure must be grounded to prevent a possible shock hazard.

WARNING:

A DB Resistor may generate enough heat to ignite combustible

 

materials. To avoid fire hazard, keep all combustible materials

 

and flammable vapors away from brake resistors.

WARNING:

The user must provide an external hard-wired emergency stop

 

circuit to disable the control in the event of an emergency.
