Warnings
VACON
®
20 X AC drive is meant for
fixed installations only
.
Only DVC A circuits (Decisive Voltage Class A, according to IEC 61800-5-1) are allowed
to be connected to the control unit.
This advice aims to protect both the drive and the cli-
ent-application. VACON
®
is not responsible for direct or consequential damages result-
ing from unsafe connections of external circuits to the drive. See paragraph 1.6 for more
details.
Do not perform any measurements
when the AC drive is connected to the mains.
The
touch current
of VACON
®
20 X drives exceeds 3.5mA AC. According to standard
EN61800-5-1,
a reinforced protective ground connection
must be ensured. See para-
graph 1.5.
If the AC drive is used as a part of a machine, the
machine manufacturer is responsible
for providing the machine with a
supply disconnecting device
(EN 60204-1). See para-
graph 4.1
Only
spare parts
supplied by VACON
®
can be used.
At power-up, power brake or fault reset,
the motor will start immediately
if the start sig-
nal is active, unless the pulse control for Start/Stop logic has been selected.
Furthermore, the I/O functionalities (including start inputs) may change if parameters,
applications or software are changed. Disconnect, therefore, the motor if an unexpected
start can cause danger. This is valid only if STO inputs are energized. For prevention on
unexpected restart, use appropriate safety relay connected to the STO inputs.
The
motor starts automatically
after automatic fault reset if the autoreset function is
activated. See the Application Manual for more detailed information.
This is valid only if STO inputs are energized. For prevention on unexpected restart, use
appropriate safety relay connected to the STO inputs.
Before performing any measurement on the motor or the motor cable
, disconnect the
motor cable from the AC drive.
Do not perform any voltage withstand test on any part of VACON
®
20 X. The tests shall be
performed according to a specific procedure. Ignoring this procedure may damage the
product.
Do not touch the components on the circuit boards
. Static voltage discharge may damage
the components.
Check that the
EMC level
of the AC drive corresponds to the requirements of your supply
network.
In a domestic environment, this product may cause radio interference, in which case sup-
plementary mitigation measures may be required.
Optional keypad is IP66/Type 4X outdoor rated. Strong exposure to direct sunlight or to
heavy temperatures might cause the degradation of display LCD.
