OMMISSIONING
Before commissioning, note the following directions and warnings:
Internal components and circuit boards of Vacon 100 X drive (except for the gal-
vanically isolated I/O terminals) are live when it 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
and the brake resistor terminals
R-/R+
are live
when Vacon 100 X drive is connected to 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 mains.
Do not make any connections to or from the frequency converter when it is con-
nected 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 30 more seconds before doing any work
on the connections of Vacon100 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 start-
ing 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.
