Quick Start Guide for Fan Applications
This guide is to simplify the start up of the MA7200 PLUS Inverter series, 3 to 75 HP, for fan
applications. It is not intended to replace the MA7200 PLUS Installation and Operation Manual, and
the user is urged review this manual. There are three methods of control or combinations thereof that
that may be selected; Keypad, Analog Signal (external terminal), or Serial Communication. Only
Keypad and analog signal control will be covered as serial communication is beyond the scope of this
manual. For serial communication control or special external control, the user is referred to the
MA7200 PLUS Installation and Operating Manual.
SAFETY FIRST!
Step 1 - Before Starting the Inverter
• Referring to the MA7200 PLUS Instruction Manual, please review and verify that the correct
inverter size for the associated motor was received free of damage. To ensure personnel safety
and to avoid equipment damage, follow the precautions and the installation procedures for
mounting, wiring, and operating environment.
CAUTION - To avoid damage to the inverter when removing the inverter cover
and/or LCD Operator, refer to Appendix B for the proper procedure.
• In accordance applicable codes make electrical connections to the motor and input power
terminals. (Refer to the block diagram, Fig. 4). No other external connections should be made at
this time, as the initial control will be from the keypad.
Step 2 - Apply Power to the Drive
• Apply AC power to the Inverter and observe the LCD Display Line 1; it should read
“Freq. Cmd 000.00Hz”. Line 2 should read “TECO”. The red LED on the STOP key should be on.
The DRIVE and FWD LED’s should be on. (See Fig. 1 below)
Step 3 - Set Drive to Run Mode
• If the red DRIVE LED is not on with AC power up, press the PGRM / DRIVE key until the red
Drive LED is on. The Inverter is now in the RUN mode.
