Safety instructions
WARNING!
THE ELECTRICAL INSTALLATION MAY ONLY BE CARRIED OUT BY A
COMPETENT ELECTRICIAN!
The components of the frequency converter power unit are live when the
frequency converter is connected to mains potential.
Getting into contact with these live components is extremely dangerous
and may cause severe injury or even death.
The control unit is isolated from the potential.
The motor terminals U,V,W and the DC-link/brake resistor terminals (–/+) are
live, even if the motor is not running.
The control I/O-terminals are isolated from the mains potential. However,
the relay outputs and other I/O-terminals may have a dangerous control
voltage present even if the frequency converter is disconnected from mains.
The frequency converter generates a high capacitive leakage current.
Only genuine BOGE spare parts may be used.
The frequency converter is meant for fixed installations only.
Do not perform any measurements as long as the frequency converter is still
connected to the mains.
After disconnecting the frequency converter from the mains, wait until the fan
stops and the indicators on the keypad go out (if no keypad is connected
observe the indicators on the housing). Wait 5 more minutes before starting
any work on the frequency converter. Do not even open the housing before
this time has expired.
Do not perform any voltage proof tests on any part of the frequency converter.
Inspections and tests should be performed in accordance with the appropriate inspection and test procedures to avoid damage to the product.
Prior to measurements on the motor or the motor cable, disconnect the motor cable from the frequency converter.
Do not touch the integrated circuits on the circuit boards. Static voltage discharge may damage the components.
Before connecting the frequency converter to mains make sure that the front
cover and the cable covers are closed.
Frequenz.pm6.5 - USA

Frequency converter
BOGE – VACON frequency converter for screw compressors
The frequency converter must always be earthed with an earth conductor
connected to the earth terminal .
The earth-fault protection protects only the converter itself against earth
faults in the motor or the motor cable.
Due to the high capacitive currents inside the frequency converter, residualcurrent circuit breakers may not function properly.
Comply with EN 50178, chapter 5.2ff (VDE 0160).
Please note the directions given in the chapter "Electrical connection" of the
operating instructions for the compressor.
Warning symbols
For your own safety, please pay special attention to the instructions marked
with the following symbol:
Dangerous voltage
General warning
Hot surface
Warning!
This is a product of the restricted sales distribution class according to IEC
61800-3. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.
While operating the equipment interferences in the civil radio communication
may occur in the proximity of the compressor under extremely unfavorable
conditions.
In normal conditions, BOGE NX frequency converters are maintenance-free.
However,we recommend to clean the heat sink with compressed air whenever necessary.
Simply the ventilator has to be replaced after approx. 45.000 operating hours.
This work may only be carried out by a specialist authorised by BOGE.

The control keypad is the link between the BOGE frequency converter and the
user. The control keypad features an alphanumeric display with seven status
displays (RUN, , READY, STOP, ALARM, FAULT) and three indicators for
the control place (I/O term/Keypad/BusComm).
Furthermore the control keypad has three status LEDs (green – green – red).
A detailed description you will find in the chapter "Status LEDs (green –
green – red)".
The control information, i.e. menu number, menu description or displayed
value and the numeric information are presented in three text lines.
The frequency converter can be operated by means of the nine push-buttons of the control keypad. Furthermore, the buttons can be used for setting
parameters or displaying operational data
The keypad is detachable and isolated from the input line potential.
Drive status displays
The drive status displays tell the user what the status of the motor and the
drive is and whether the motor control software has detected irregularities in
motor or frequency converter functions.
