WARNING: Dynamic brake resistors may generate enough heat to ignite
combustible materials. Keep all combustible materials and
flammable vapors away from brake resistors.
Caution:
Suitable for use on a circuit capable of delivering not more than the
RMS symmetrical short circuit amperes listed here at rated voltage.
Horsepower
RMS Symmetrical Amperes
1–50
5,000
51–200
10,000
201–400
18,000
401–600
30,000
601–900
42,000
Caution:
Do not supply any power on the External Trip (motor thermostat)
leads at J4-16 or J4-17 as the control may be damaged. Use a dry
contact type that requires no external power to operate.
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 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 provide unstable
power to the motor controller. Instead, we recommend using a four
wire Wye.
Caution:
If the DB hardware mounting is in any position other than vertical,
the DB hardware must be derated by 35% of its rated capacity.
