Start The Controller At V/Hz Regulation Mode; Start-Up Check List - Reliance electric GV3000/SE Instruction Manual

Start the Controller at V/Hz Regulation Mode

Start-up Check List

1. Install equipment and options in accordance to manual 49'1327, Section 3 and relevant manuals
listed in Section 2 of this manual.
2. Turn OFF, lockout or tag input power of the controller.
Whenever work is done on the unit AC-input power must be disconnected and the
DANGER
DC-bus voltage checked with a voltmeter. Verify that this voltage has dropped below
DC 50 V (approx. 60 sec). For DC-bus voltage check and test points refer to Power Units
: manual 491327, Section 4.
Failure to observe this precaution could result in bodily injury or loss of life.
3. Check the power circuit installation (see manual 49'1327, Section 3).
• It is essential to observe and allow for all the national specifications and provisions relating to the
installation and operation of electrical systems.
• Check rated data, function and circuitry of branch circuit protection and/or line input fuses.
• Check all the terminal connections to ensure that they are tight.
4. Check of all safety devices such as emergency stop switches etc. to ensure they operate properly.
• Verify that the user-installed COAST-STOP push-button is installed. You must remove the
factory-installed wire jumper at regulator terminal block, for the COAST-STOP to work.
For terminal numbers refer to manual 49'1327, Section 3.
• Check all wiring of control connections.
5. Check all equipment for mechanical damage. Remove any debris from around the controller. (Use
clean, dry compressed air with a maximum gauge pressure of 1 bar in order to clean any metallic
installation residues from the equipment).
• Check that there is adequate clearance around the controller.
6. Check that line voltage and equipment voltage are properly matched.
7. Check the motor and equipment ground. Check line input terminals as well as motor windings
terminals for shorting to ground. It is not permitted to connect different ground potentials to the
controller as this may result in short-circuits.
• Verify that a properly sized ground wire is installed and that a suitable earth ground is used.
Verify that all ground leads are run unbroken.
8. Check that the motor and equipment rated data are matched.
9. Check whether the motor is correctly connected. Disconnect any power correction capacitors
connected to the motor.
10. Uncouple the motor from any driven machinery to initially start the controller.
11. Before continuing start-up, first read descriptions in Section 4 of 'General Parameters' and Section 5
of 'V/Hz Parameters' and in this way acquire an overview of the various application features, setting
facilities and setting ranges of the inverter. Compare the possible application features and their
factory settings with the requirements of the installed drive, and take such settings into
consideration before start-up with motor.
12. DC Bus voltage, capacitor preparation and line voltage test:
• Switch on the line voltage.
• If more than six months have passed since delivery of the equipment, the unit should be left in
this state for 15 minutes. This is necessary for forming the intermediate circuit capacitors.
• Compare actual line input voltage with the H.021 adjustment and correct if the deviation is
greater than 10%.
• Switch the line voltage off.
