2 Safety
2.1 Safety
The following symbols are used in this guide:
WARNING
Indicates a potentially hazardous situation that could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that could result in minor or moderate injury. It can also be used to alert against unsafe practices.
NOTICE
Indicates important information, including situations that can result in damage to equipment or property.
2.1.1 Quali€ed Personnel
Correct and reliable transport, storage, installation, operation, and maintenance are required for the troublefree and safe operation of the soft starter. Only quali€ed personnel are allowed to install or operate this equipment.
Quali€ed personnel is de€ned as trained staff, who are authorized to install, commission, and maintain equipment, systems, and circuits in accordance with pertinent laws and regulations. Additionally, the personnel must be familiar with the instructions and safety measures described in this manual.
WARNING
ELECTRICAL SHOCK HAZARD
VLT® Soft Starter MCD 500 contains dangerous voltages when connected to mains voltage. Only a quali€ed electrician should carry out the electrical installation. Improper installation of the motor or the soft starter can cause death, serious injury, or equipment failure. Follow the guidelines in this manual and local electrical safety codes.
Models MCD5-0360C ~ MCD5-1600C:
Treat the busbar and heat sink as live parts whenever the unit has mains voltage connected (including when the soft starter is tripped or waiting for a command).
2 2
WARNING
PROPER GROUNDING
Disconnect the soft starter from mains voltage before carrying out repair work.
It is the responsibility of the person installing the soft starter to provide proper grounding and branch circuit protection according to local electrical safety codes.
Do not connect power factor correction capacitors to the output of the VLT® Soft Starter MCD 500. If static power factor correction is employed, it must be connected to the supply side of the soft starter.
WARNING
IMMEDIATE START
In auto-on mode, the motor can be controlled remotely (via remote inputs) while the soft starter is connected to mains.
MCD5-0021B ~ MCD5-0961B:
Transportation, mechanical shock, or rough handling may cause the bypass contactor to latch into the On state.
To prevent the motor from starting immediately on €rst commissioning or operation after transportation:
•Always ensure that the control supply is applied before the power.
•Applying control supply before power ensures that the contactor state is initialized.
WARNING
UNINTENDED START
When the soft starter is connected to AC mains, DC supply, or load sharing, the motor can start at any time. Unintended start during programming, service, or repair work can result in death, serious injury, or property damage. The motor can start with an external switch, a €eldbus command, an input reference signal from the LCP or LOP, via remote operation using MCD PC Software, or after a cleared fault condition.
To prevent unintended motor start:
•Press [Off]/[Reset] on the LCP before programming parameters.

VLT® Soft Starter MCD 500 |
4 Electrical Installation
4.1 Control Wiring
4.1.1 Ways to Control the Soft Starter
4 |
|
4 |
Control the VLT® Soft Starter MCD 500 in 3 ways: |
|
|
• |
Pressing the keys on the LCP. |
||
|
|
|
• |
Via remote inputs. |
|
|
|
||
|
|
|
• |
Via a serial communication link. |
The soft starter always responds to a local start or stop command (via the [Hand On] and [Off] keys on the LCP). Pressing the [Auto On] key selects remote control (the soft starter accepts commands from the remote inputs). In remote mode, the Auto On LED is on. In hand-on mode, the Hand On LED is on if the soft starter starts or runs. The Off LED is on if the soft starter is stopped or stops.
4.1.2 Control Terminals
Control terminations use 2.5 mm2 (14 AWG) plug-in terminal blocks. Different models require control voltage to different terminals:
•CV1 (24 V AC/V DC): A5, A6.
•CV2 (110–120 V AC): A5, A6.
•CV2 (220–240 V AC): A4, A6.
Illustration 4.1 Wiring to Control Terminals
NOTICE
Do not short terminals 05 and 06 without using a thermistor.
All control terminals and relay terminals comply with SELV (safety extra low voltage). This protection does not apply to grounded delta leg above 400 V.
To maintain SELV, all connections made to the control terminals must be PELV (for example thermistor must be reinforced/double insulated from motor).
NOTICE
SELV offers protection by way of extra low voltage. Protection against electric shock is ensured when the electrical supply itself is of the SELV type and the installation follows local/national regulations on SELV supplies.
NOTICE
Galvanic (ensured) isolation is obtained by ful€lling requirements for higher isolation and by providing the relevant creepages/clearance distances. These requirements are described in the IEC 61140 standard. The components that make up the electrical isolation also comply with the requirements for higher isolation and the relevant test as described in IEC 61140.
4.1.3 Remote Inputs
The soft starter has 3 €xed inputs for remote control. Control these inputs by contacts rated for low voltage, low current operation (gold flash or similar).

4.1.4 Serial Communication
Control via the serial communication network is always enabled in hand-on mode and can be enabled or disabled in remote control mode (see parameter 3-2 Comms in Remote). Control via the serial communication network requires an optional communication module.
4.1.6 Power Terminations
NOTICE
For personnel safety, snap-off tabs protect the power terminals on models up to MCD5-0105B. When using large cables, it may be necessary to break off these tabs.
4.1.5 Ground Terminal
Ground terminals are at the back of the soft starter.
•MCD5-0021B to MCD5-0105B have 1 terminal on the input side (top).

4.3.1 Testing the Installation
The VLT® Soft Starter MCD 500 can be connected to a small motor for testing. During this test, the control input and relay output protection settings can be tested. This test mode is not suitable for testing soft starting or soft stopping performance.
4 4 The minimum FLC of the test motor is 2% of the minimum FLC of the soft starter (see chapter 4.5 Minimum and Maximum Current Settings).
NOTICE
When testing the soft starter with a small motor, set parameter 1-1 Motor FLC to the minimum allowable value.
Models which are internally bypassed do not require an external bypass contactor.

4.3.3.3 Externally Bypassed
Non-bypassed models have dedicated bypass terminals, which allow the soft starter to continue providing protection and monitoring functions even when bypassed via an external bypass contactor. Connect the bypass contactor to the bypass terminals and control the contactor by a programmable output con€gured to Run
(see parameters 4-1 to 4-9).
NOTICE
The bypass terminals on MCD5-0245C are:
•T1B.
•T2B.
•T3B.
The bypass terminals on MCD5-0360C to MCD5-1600C are:
•L1B.
•L2B.
•L3B.
If necessary, the fuses can be installed on the input side.
