1.3 Danger
1.4 Warnings
The components of the power unit of VACON
®
100 X drives are live when the drive is con-
nected 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-terminals are live
when VACON
®
100 X Drive is connected to the 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 an additional 30 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 measuring equipment to absolutely
ensure that no
voltage is present. Always ensure absence of voltage before starting any elec-
trical 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 the 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 keypad go out (if no keypad is connected, see the
indicators on the cover). Wait an additional 30 seconds before starting any work on the drive.
The terminals are live when the VACON
®
100X Drive is connected to a photovoltaic system.
Photovoltaic cells generate DC voltage even at low intensity of sunlight.
Wait 30 seconds until the drive is discharged, before switching between AC and DC supply
(photovoltaic system) and vice versa.
VACON
®
100 X AC drive is meant for fixed installations (on the motor or on the wall) 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 client-
application. VACON
®
is not responsible for direct or consequential damages resulting
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
®
100 X AC drives exceeds 3.5mA AC. According to standard
EN61800-5-1, a reinforced protective ground connection must be ensured. See para-
graph 1.5 for more details.
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 for more details.
