(2) Wiring

 Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of

the inverter.

 The connection orientation of the output cables U, V, W to the motor will affect the direction of

rotation of the motor.

 Incorrect terminal wiring could result in the equipment damage.  Reversing the polarity (+/-) of the terminals could damage the inverter.  Only authorized personnel familiar with Cerus inverter should perform wiring and inspections.  Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily

injury.

(3) Test run

 Check all parameters prior to operation. Changing parameter valu es might be required depending

on the load.

 Always apply permissible range of voltage to the each terminal as indicated in this manual.

Otherwise, it could lead to inverter damage.

(4) Operation precautions

 When the Auto rest art function is selected, stay away from the equipment as a motor will restart

suddenly after a fault stop.

 The Stop key on the key pad is valid only when the appropriate function setting has been made.

Prepare an emergency stop switch separately.

 If a fault reset is made with the reference signal present, a sudden start will occur. Check that the

reference signal is turned off in advance. Otherwise an accident could occur.

 Do not modify or alter anything inside the inverter.  Motor might not be protected by electronic thermal function of inverter.  Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.  Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic

♣ The same rule applies to Function group 2 and I/O group.

-. In F 1, continue pressing the Up (S) key until F15 is displayed.

-. Moving to F15 has been complete.

♣ Note: Some codes will be skipped in the middle of increment (S)/decrement (T) for code change. That is because it is programmed that some codes are intentionally left blank for future use or the codes user does not use are invisible. For example, when F23 [High/low frequency limit select] is set to “O (No) ”, F24 [High frequency limit] and F23 [Low frequency limit] are not displayed during code change. But When F23 is set to “1(Yes)”, F23 and F24 will appear on the display .
