Read and understand these instructions before performing any procedure on this drive.
HAZARDOUS VOLTAGE
• Read and understand this manual before installing or operating the MT Series driv e. Installation, adjustment, repair and maintenance must be performed by qualified personnel.
• The user is responsible for compliance with all international and national electrical standards in force concerning protective grounding of al l equipment.
• Many parts of this variable speed drive, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH. Use only electrically insulated tools.
• DO NOT touch unshielded components or terminal strip screw connections with voltage present.
• DO NOT short across terminals PA/+ and PC/- or across the DC bus capacitors.
• Install and close all the covers before applying power or starting and st opping the drive.
• Before servicing the variable speed drive:
- Disconnect all power.
- Place a “DO NOT TURN ON” label on the variable speed drive disconnect.
- Lock the disconnect in the open position.
• Disconnect all power including external control power that may be present before servicing the drive. Wait for the charging LED to go off. Then follow the DC bus voltage measurement procedure given on page 21 45 V. The drive LEDs are not accurate indicators of the absence of DC bus voltage.
Electric shock will result in death or serious injury.
DANGER

CAUTION
IMPROPER DRIVE OPERATION
• If the drive is not turned on for a long period, the performance of its electrol ytic capacitors will be reduced.
• If it is stopped for a prolonged period, turn the drive on every two years for at least 5 hours to restore the performance of the capacitors, then check its operation. It is recommended that the drive is not connected directly to the line vo ltage. The vol tage should be increased gradually using an adjustable AC source.
Failure to follow these instructions can result in equipment damage.

Steps for setting up the drive
INSTALLATION
b 1 Take delivery of the drive
v Check that the catalog number printed on the label is the same
as that on the purchase order
v Remove the MT Series from its packaging and check that it has
not been damaged in transit
b 2 Check the line voltage
v Check that the line voltage is compatible with the
voltage range of the drive (see pages 8 and 9)
Steps 1 to 4 must be performed with the power off
b 3 Mount the drive
v Mount the drive in accordance with the instructions
in this document
v Install and connect the DC choke (see page 11) v Install any internal and external options
b 4 Wire the drive
v Connect the motor, ensuring that its
connections correspond to the voltage
v Connect the line supply, after making sure that
it is turned off
v Connect the control v Connect the speed reference

nary recommendations
Installing the drive
- Mount the drive on a wall or in the ba ck of the enclosure, in accordance with the recommendations describ ed in this document, before installing the DC choke.
Installing the DC choke
MT275 to MT2100 and MT4125 to MT4400 drives are supplied with a DC choke that must be installed on the top of the drive and wired in accordance with the recommendations described in this document. This choke must be used for connecting drives to the 3-phase line supply.
- Mount the DC choke on the back of the enclosure or on the wall on top of the drive, and connect it. The instructions for instal connecti
- Check that the seal between the drive and the choke chassis is performing its role correctly.
ng the choke are given on page
11.
Recommendations
Read and understand the instructions in the Programming Manual.
CAUTION
INCOMPATIBLE LINE VOLTAGE
Before turning on and configuring the drive, ensure t hat the line voltage is comp atible with the supply volt age range shown on the drive nameplate. The drive may be damaged if the line vol tage is not compatible.
Failure to follow this instruction can result in equipment damage.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Before turning on and configuring the MT Series, check that the PWR (POWER REMOVAL) input is deactivated (programmedto 0) in order to prevent unintended operation. Do not forget to reactivate the Power Removal input to start the motor.
• Before turning on or on exiting the configuration menus, check that t he inputs assigned to the run command are deactivated (programmed to 0) since they can cause the motor to start immediately.
Failure to follow these instructions will result in death or serious injury.
ling and
If the safety of personnel requires the prohibition of unwanted or unintended operation, electronic locking is performed by the MT Series “Power Removal” function. This function requires the use of connection diagrams conformin level 2 according to IEC/EN 61508. The Power Removal function takes priority over any run command.
