Caution:

Suitable for use on a circuit capable of delivering not more than the

 

RMS symmetrical short circuit amperes listed here at rated voltage.

Caution:

Disconnect motor leads (T1, T2 and T3) from control before you

 

perform a “Megger” 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:

Do not supply any power to the External Trip (motor thermostat)

 

leads at J1-16 and 17. Power on these leads can damage the

 

control. Use a dry contact type that requires no external power to

 

operate.

 

Caution:

Do not connect AC power to the Motor terminals T1, T2 and T3.

 

Connecting AC power to these terminals may result in damage to

 

the control.

 

Caution:

Baldor recommends not using “Grounded Leg Delta” transformer

 

power leads that may create ground loops and degrade system

 

performance. Instead, we recommend using a four wire Wye.

Caution:

Do not use power factor correction capacitors at the input power

 

lines to the 22H Line Regen control. Installing power factor

 

correction capacitors may damage the control.
