Safety Instructions
Instruction manual
Read this instruction manual before using the Variable
Speed Drive, VSD.
Handling the variable speed drive
Installation, commissioning, demounting, taking meas-
urements, etc, of or on the variable speed drive may
only be carried out by personnel technically qualified
for the task. The installation must be carried out in
accordance with local standards.
Opening the variable speed drive
Always take adequate precautions before opening the
variable speed drive. Although the connections for the
control signals and the switches are isolated from the
main voltage, do not touch the control board when the
variable speed drive is switched on.
Precautions to be taken with a
connected motor
If work must be carried out on a connected motor or on
the driven machine, the mains voltage must always be
disconnected from the variable speed drive first. Wait
at least 5 minutes before starting work.
Earthing
The variable speed drive must always be earthed via
the mains safety earth connection.
Earth leakage current
This variable speed drive has an earth leakage current
which does exceed 3.5 mA AC. Therefore the minimum
size of the protective earth conductor must comply with
the local safety regulations for high leakage current
equipment which means that according the standard
IEC61800-5-1 the protective earth connection must be
assured by one of following conditions:
1. Use a protective conductor with a cable cross-sec-
tion of at least 10 mm
2
for copper (Cu) or 16 mm
2
for aluminium (Al).
2. Use an additional PE wire, with the same cable
cross-section as the used original PE and mains
supply wiring.
Residual current device (RCD)
compatibility
This product cause a DC current in the protective con-
ductor.
Where a residual current device (RCD) is used
for protection in case of direct or indirect contact, only a
Type B RCD is allowed on the supply side of this prod-
uct. Use RCD of 300 mA minimum.
EMC Regulations
In order to comply with the EMC Directive, it is abso-
lutely necessary to follow the installation instructions.
All installation descriptions in this manual follow the
EMC Directive.
Mains voltage selection
The variable speed drive may be ordered for use with
the mains voltage range listed below.
JNFX40/48: 230-480 V
JNFX50/52: 440-525 V
JNFX69: 500-690 V
Voltage tests (Megger)
Do not carry out voltage tests (Megger) on the motor,
before all the motor cables have been disconnected
from the variable speed drive.
Condensation
If the variable speed drive is moved from a cold (stor-
age) room to a room where it will be installed, conden-
sation can occur. This can result in sensitive
components becoming damp. Do not connect the
mains voltage until all visible dampness has evapo-
rated.
Incorrect connection
The variable speed drive is not protected against incor-
rect connection of the mains voltage, and in particular
against connection of the mains voltage to the motor
outlets U, V and W. The variable speed drive can be
damaged in this way.
Power factor capacitors for improving
cos
ϕ
Remove all capacitors from the motor and the motor
outlet.
Precautions during Autoreset
When the automatic reset is active, the motor will
restart automatically provided that the cause of the trip
WARNING: Always switch off the mains voltage
before opening the variable speed drive and
wait at least 5 minutes to allow the buffer
capacitors to discharge.
