This manual contains clearly marked cautions and warnings which are intended for your per-
sonal safety and to avoid any unintentional damage to the product or connected appliances.
Please read the information included in cautions and warnings carefully.
Vacon 100 X is a drive conceived for controlling asynchronous AC motors and permanent
magnet motors. The product is inteded to be installed in a restricted access location and for
a general purpose use.
Only by Vacon authorized, trained and qualified personnel are allowed to install, operate and
maintain the drive.
The cautions and warnings are marked as follows:
Table 1. Warning signs.
1.1
Danger
= DANGEROUS VOLTAGE!
= HOT SURFACE
= WARNING or CAUTION
The
components of the power unit of
Vacon 100 X drives
are live
when the drive
is connected to mains potential. Coming into contact with this voltage is
extremely dangerous
and may cause death or severe injury.
The
motor terminals (U, V, W), the brake resistor terminals and the DC-termi-
nals are live
when Vacon 100 X Drive is connected to mains, even if the motor is
not running.
After disconnecting
the AC drive from the mains,
wait
until the indicators on the
keypad go out (if no keypad is connected, see the indicators on the cover). Wait 30
more seconds before doing any work on the connections of Vacon 100 X Drive. Do
not open the unit before this time has expired. After expiration of this time, use a
measuring equipment to absolutely ensure that no voltage is present.
Always
ensure absence of voltage before starting any electrical work!
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 when Vacon 100 X drive is disconnected from mains.
Before connecting
the AC drive to mains make sure that the powerhead of Vacon
100 X Drive is mounted firmly on the terminal box.
During a coast stop (see the Application Manual), the motor is still generating
voltage to the drive. Therefore, do not touch the components of the AC drive
before the motor has completely stopped and wait until the indicators on the key-
pad go out (if no keypad is connected, see the indicators on the cover). Wait addi-
tional 30 seconds before starting any work on the drive.
