PRECAUTIONS
(1) Handling and installation
•Check VFD environmental conditions and electrical requirements before purchasing
VFD.
•The higher HP rated P series VFD can be heavy. Lift according to the weight of the
product. Use a hoist or crane to move and install VFD if necessary. Failure to do so may
result in personal injury or damage to the VFD.
•Do not stack VFD boxes higher than the number recommended.
•Do not place heavy items on VFD.
•Install and wire VFD according to the instructions in this manual.
•Do not open the cover during delivery.
•Do not drop VFD or subject it to hard impact.
•Verify if ground impedance is less than 100for 230V Class VFDs and 10for 460V
class VFDs.
•Take protective measures against ESD (Electrostatic Discharge) before touching control
boards during inspection, installation or repair.
(2) Wiring
•Input power wires should be connected to R, S and T VFD terminals for three-phase
power or R and S for a single-phase power. Power Ground and Motor Ground should
be connected to a VFD ground terminal.
•Do not connect any wires, except dynamic braking unit or DC reactor, to VFD terminals
N, P1 or P2.
•Do not connect power factor correction capacitors, surge suppressors, or RFI filter to
the VFD output.
•The phase sequence on VFD terminals U, V, W to motor will affect the direction of
motor rotation. The input power phase sequence does not affect a direction of motor
rotation.
•Incorrect VFD terminal wiring could result in VFD and/or equipment damage.
•Reversing the polarity (+/-) of the digital control terminals can damage VFD.
•Only authorized personnel familiar with CERUS VFDs should perform wiring and start-
up.
•Perform wiring after VFD installation is done. Otherwise, electric shock or bodily injury
can occur.
(3) Start-up
•Check if input power voltage is within acceptable range before applying power to VFD
•Check all the motor data and control parameters when VFD is powered. Some
parameter values might require adjustment depending on the application.
•Start VFD in forward direction and check the motor rotation. Swap any two motor
leads to change the motor rotation when VFD power is off . It is not recommended to
correct motor rotation by using reverse start command to run motor forward.
•Run motor up to full speed and check if system has resonance frequencies (vibration) in
the normal speed range. Make notes at what frequencies the vibration started and
stopped. Set these frequencies in Jump Frequency parameters to prevent a system
vibration.
•Check the motor run current on VFD display when run at full speed and if it is higher
than motor FLA, check motor wiring and for any mechanical problems (valves, dampers,
etc) that could create extra load on motor shaft. If the wiring is correct and there is no
any mechanical problem, stop VFD, change control mode from V/F to Sensorless and
run auto-tune. If the motor has different motor winding parameters of standard industrial
motor, this procedure will fix the problem.

iv
(4) Operation
•When the Auto restart function is selected, VFD can restart multiple times automatically
during operation.
•The Stop key on the keypad can only be used to stop VFD when Local control is
enabled. Install a separate emergency stop circuit if necessary.
•If restart after fault reset is selected, the VFD can start automatically after fault reset.
•Do not modify VFD internal components and circuits.
•Set correct motor data from the motor nameplate and overload protection parameters
for proper motor overload protection.
•The use of any disconnecting device (contactor, disconnect etc.) in motor circuit during
VFD run can cause a damage of VFD power components. Stop VFD before opening the
motor circuit with disconnect or contactor.
•Install line reactor or harmonics filter to reduce harmonics distortion and EMI/RFI filter
for electromagnetic and high frequency interference to sensitive electronic equipment.
•Install a line reactor if input power is unbalanced or distance from VFD to power
transformer is greater than 45 feet to increase VFD protection from transient power
surges.
•Power factor capacitors and generators may become overheated and damaged due to
harmonics distortion created by VFD.
•Use, if possible, an inverter rated motor or motor with insulation class “F” or higher. The
VFD generates high frequency output pulses with spikes, which can deteriorate motor
winding insulation and eventually damage the motor. The longer distance to the motor
the higher amplitude of these voltage spikes will be applied to motor winding. Any
cables with paralleled wires will increase the amplitude of these spikes at motor
terminals.
•Install output reactor to protect motor winding insulation in 380-480V applications if
distance from VFD to the motor is greater than 45 feet or if motor is old or insulation
class is lower than “F”. Install output filter in the same application if distance is greater
than 100 feet.
•Install output filter to protect motor winding insulation in 200-230V applications if
distance from VFD to the motor is greater than 200 feet.
•Use dynamic braking unit and resistor in high inertia applications when VFD trips on
Overvoltage during deceleration if short deceleration time is required.
•VFD can operate motor at frequency higher than 50HZ or 60Hz. Verify the maximum
allowed speed with motor and machinery manufacturers prior to increasing a VFD
output frequency because it can overheat motor or damage machinery.
•The DC-Braking mode produces an extra motor braking force but does not provide a
holding torque.
(5) Safety
•If required, provide an emergency mechanical brake to prevent any hazardous
conditions when VFD fails during operation.
•Some VFD parameters are set as default to automatically start VFD in some
applications. Disable these parameters if automatic start is not safe for personnel or
equipment.
(6) Maintenance, inspection and parts replacement
•Disconnect all motor leads from VFD before checking the motor insulation with Megger
tester. The Megger tester 1000VDC output can damage the VFD power components.
•Refer to Chapter 8 for periodic inspection and parts replacement details.
(7) Disposal
•Dispose of VFD properly as an industrial equipment wastes.
