 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

equipment may be affected.

 In case of input voltage unbalance, install AC reactor. Power Factor capacitors and generators may

become overheated and damaged due to potential high frequency noise transmitted from inverter.

 Before operating unit and prior to user programming, reset user parameters to default settings.  Inverter can easily be set to high-speed operations. Verify capability of motor or machinery prior to

operating unit.

 Stopping torque is not produced when using the DC-Brake function. Install separate equipment

when stopping torque is needed.

(5) Fault prevention precautions

 Provide a safety backup such as an emergency brake, which will prevent the machine and

equipment from hazardous conditions if the inverter fails.

 When it is desired to avoid resonance attributable to the natural frequency of a

mechanical system, these parameters allow resonant frequencies to be skipped. Three different areas of [Skip frequency High/Low limit] can be set with the skip frequencies set to either the top or bottom point of each area. However, during acceleration or deceleration, the run frequency within the set area is valid.

 In the case of increasing frequency setting as shown above, if frequency set value

(Analog setting via voltage, current or digital setting via keypad) i s within the range of Skip frequency, it maintains Skip frequency low limit value. If the set value is outside the range, it increases the frequency.

 In the case of decreasing frequency setting, if frequency set value (Analog setting via

voltage, current or Digital setting via keypad) is within the rang e of Skip frequency, it maintains Skip frequency high limit value. If the set value is outside the range, it decreases the frequency.
