■ Warnings
■ High Voltage Warning
The MCD 200 contains dangerous
voltages when connected to line voltage.
Only a competent electrician should carry
out the electrical installation. Improper installation of
the motor or the MCD 200 may cause equipment
failure, serious injury or death. Follow this manual,
National Electrical Codes (NEC
®
) and local safety
codes.
■ Safety Regulations
1. The soft starter must be disconnected from the
mains if repair work is to be carried out.
It is the responsibility of the user or the
person installing the MCD 200 to provide
proper grounding and branch circuit
protection according to the National Electrical Code
(NEC
®
) and local safety codes.
■ Warning Against Unintended Start
1. The motor can be brought to a stop by means of
digital or bus commands while the soft starter is
connected to the mains.
If personal safety considerations make it
necessary to ensure that no unintended start
occurs, these stop functions are not sufficient.
2. A motor that has been stopped may start if faults
occur in the electronics of the soft starter, or a
temporary fault in the supply mains or the motor
connection ceases.

Avoiding Soft Starter Damage
Please read and follow all instructions in this manual.
Additionally, take special note of the following:
1. Do not connect power factor correction
capacitors to the soft starter output. Static power
factor correction, if used, must be connected on
the mains side of the soft starter.
2. Do not apply incorrect voltages to the MCD 200
control inputs.
Electrostatic Precaution: Electrostatic
discharge (ESD). Many electronic
components are sensitive to static
electricity. Voltages so low that they cannot be felt,
seen or heard, can reduce the life, affect performance,
or completely destroy sensitive electronic
components. When performing service, proper ESD
equipment should be used to prevent possible
damage from occurring.
