WARNING
The motor terminals U, V, W and the DC-link/brake resistor
terminals are
live
when the Liquid-Cooled drive is connected to
mains,
even if the motor is not running
.
WARNING
After disconnecting the drive from the mains, wait until the
indicators on the keypad go out (if no keypad is attached see the
indicators on the cover). Wait 5 more minutes before doing any
work on the Liquid-Cooled drive connections. Do not touch the
enclosure before this time has expired.
WARNING
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 the Liquid-Cooled
drive is disconnected from mains.
Cautions
CAUTION
Always remove all cooling agent from the cooling element(s)
before shipping to avoid damage caused by freezing.

Liquid-Cooled drive. There is a certain procedure according to
which the tests shall be performed. Ignoring this procedure may
result in damaged product.
CAUTION
Do not touch the components on the circuit boards. Electrostatic
voltage discharge may damage the components.
CAUTION
Before connecting the Liquid-Cooled drive to mains, ensure the
functionality of the coolant circulation and check the circulation for
possible leaks.
