■Warnings
MCD 200 Design Guide
■High Voltage Warning
The MCD 200 contains dangerous voltages
when co nnected to line voltage. Only a
competent electrician should carry out
the electrical installation. Improper instal lation of the
motor or the MCD 200 may cause equipment failure,
serious injury or death. Follow this manual, National
Electrical Code (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 responsibilit y 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,
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.
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 (E SD). Many electronic
components are sensitive to static
electricity. Voltages so low that they cannot b e
felt, seen o r heard, can reduce the life, affect
performance, or completely destroy sensitive
electronic co mponents. When performing service,
proper ESD equipment should be used to prevent
possible damage from occurring.

■Symbols Used in this Manual
When reading this manual you will come across
different symbols that require special attention.
The symbols used are the following:
NB!:
Indicates something to be noted by the reader
Indicates a general warning
Indicates a high voltage warning
■Avoiding Soft Starter D amage
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

■MCD 200 Series Overview
■Description
The Danfoss MCD 200 Soft Starter series
comprises two separate ranges:
• MCD 201
• MCD 202
MCD 201 and MCD 202 soft starters share a
common power and mechanical design, but offer
different levels of functionality.
MCD 201 soft starters provide TVR (Timed Voltage
Ramp) starting and stopping control and are designed
for use with an external motor protection device.
MCD 202 soft starters provide Current Limit
starting control, TVR soft stop and include a range
of motor protection functions.
NB!:
This manual makes reference to MCD
200, MCD 201 and MCD 202. The MCD
200 designation is used when referring to
characteristics common to both the MCD 201 and
MCD 202 ranges. In all other cases the text refers
to the specific range MCD 201 or MCD 202.
MCD 200 Design Guide
Overview
MCD 200 Series
MCD 200 soft starters include an integral bypass
function that bypasses the soft starter SCRs during
run. This minimises heat dissipation during run
and makes the MCD 200 suitable for installation
within non-ventilated enclosures without th
for an external bypass contactor.
