MCD 202 Series
High Voltage Warning
The MCD 202 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 202 may cause equipment failure, serious injury or death. Follow this manual, National
Electrical Codes (NEC®) and local safety codes.
Safety Regulations
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 202 to provide proper
grounding and branch circuit protection according to the National Electrical Code (NEC®) and
local safety codes.
Local regulations may require a line contactor or circuit breaker to be installed, to ensure that
the starter is completely disconnected from mains voltage in the event of a trip.
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
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 202 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.
Disposal Instructions
Equipment containing electrical components may not be disposed together with
domestic waste.
It must be collected separately as electrical and electronic waste according to
local and currently valid legislation.
