Powerup Test Caution Messages

CAUTION: Remarks for using ground fault interrupter breakers in the

main power supply: Adjustable frequency inverters with CE-filters (RFI-

filter) and shielded (screened) motor cables have a higher leakage current

toward Earth GND. Especially at the moment of switching ON this can

cause an inadvertent trip of ground fault interrupters. Because of the

rectifier on the input side of the inverter there is the possibility to stall the

switch-off function through small amounts of DC current. Please observe

the following: • Use only short time-invariant and pulse current-sensitive

ground fault interrupters with higher trigger current. • Other components

should be secured with separate ground fault interrupters. • Ground fault

interrupters in the power input wiring of an inverter are not an absolute

protection against electric shock.

..... 2–19

CAUTION: Be sure to install a fuse in each phase of the main power

supply to the inverter. Otherwise, there is the danger of fire.

..... 2–19

CAUTION: For motor leads, ground fault interrupter breakers and

electromagnetic contactors, be sure to size these components properly

(each must have the capacity for rated current and voltage). Otherwise,

there is the danger of fire.

..... 2–19

CAUTION: The heat sink fins will have a high temperature. Be careful

not to touch them. Otherwise, there is the danger of getting burned.

..... 2–22

CAUTION: The operation of the inverter can be easily changed from low

speed to high speed. Be sure to check the capability and limitations of the

motor and machine before operating the inverter. Otherwise, there is the

danger of injury.

..... 2–22

CAUTION: If you operate a motor at a frequency higher than the inverter

standard default setting (50Hz/60Hz), be sure to check the motor and

machine specifications with the respective manufacturer. Only operate

the motor at elevated frequencies after getting their approval. Otherwise,

there is the danger of equipment damage and/or injury.

.... 2–22,

..... 2–28

CAUTION: Check the following before and during the powerup test.

Otherwise, there is the danger of equipment damage. • Is the shorting bar

between the [+1] and [+] terminals installed? DO NOT power or operate

the inverter if the jumper is removed. • Is the direction of the motor

rotation correct? • Did the inverter trip during acceleration or decelera-

tion? • Were the rpm and frequency meter readings as expected? • Were

there any abnormal motor vibrations or noise?
