6. COMMISSIONING
Before commissioning, note the following directions and warnings:
Internal components and circuit boards of VACON
®
100 X drive (except for the galvan-
ically isolated I/O terminals) are live when it is connected to the mains potential.
Coming into contact with this voltage is extremely dangerous and may cause death
or severe injury.
The motor terminals U, V, W and the brake resistor terminals R-/R+ are live when
VACON
®
100 X drive is connected to the mains, 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 when VACON
®
100 X drive is disconnected from the mains.
Do not make any connections to or from the AC drive when it is connected to the
mains.
After disconnecting the AC drive from the mains, wait until the fan stops and the
indicators on the powerhead go out. 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 a measuring equipment to absolutely
ensure that no
voltage is present.
Always ensure absence of voltage before starting
any electrical work!
Before connecting the AC drive to mains make sure that the powerhead VACON
®
100
X Drive is mounted firmly on the terminal box.
