Warnings
WARNING
Only a competent electrician may carry out the electrical installation.
WARNING
The components of the power unit of the drive are live when the
SLX9000 drive is connected to power supply. Coming into contact
with this voltage is extremely dangerous and may cause death or
severe injury. The control unit is isolated from mains potential.
WARNING
The motor terminals U, V, W (T1, T2, T3) and the DC-link/brake
resistor terminals -/+ (in SLX9000
≥
1.1 kW) are
live
when drive is
connected to mains,
even if the motor is not running
. Contact with
this voltage is extremely dangerous and may cause death or severe
injury.
WARNING
The control I/O-terminals are isolated from the mains potential.
However, the relay outputs and other I/O-terminals may have
dangerous control voltage present even when the drive is
disconnected from the power supply. Contact with this voltage is
extremely dangerous and may cause death or severe injury.
WARNING
The drive has a large capacitive leakage current. Proper grounding
is required. Failure to observe this precaution could result in death
or severe injury.
WARNING
If the drive is used as a part of a machine, the machine
manufacturer is responsible for providing the machine with a main
switch (EN 60204-1).
WARNING
Only spare parts delivered by Eaton can be used.
