Warnings



Warnings

The MCD 201 & MCD 202 contain

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 201 & MCD 202 may cause

equipment failure, serious injury or death.

Follow this manual and 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.

2. Stopping the soft starter of the does not

disconnect the equipment from the mains and

leaves one phase connected to the motor. Thus

the soft starter is not to be used as a safety

switch.

It is the responsibility of the user or the

person installing the MCD 201 & MCD

202 to provide proper grounding and

branch circuit protection according to the

National Electric Code (NEC®) and local

codes.

Symbols used in this manual

The following symbols indicate items that require

special attention:

Indicates a general warning.

Indicates a high voltage warning.

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.

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.
