Warning
Even after the disconnection of all power, a dangerous residual voltage as high
as 60 V DC can still be present. For capacitor modules, this hazardous voltage
can be present for up to 30 min.
In order to ensure that no hazardous voltages are present, the voltage must be
first carefully measured (generator principle when motors are rotating). If this is
not observed, then this can result in injury due to electric shock.
For this reason, opening the device or removing the cover is permitted only
after up to 30 minutes have elapsed (depending on the degree of expansion)
since the device was switched to the voltage–free state. All covers must be
reattached before the line voltage is switched on. Operation of the plant with
damaged DC link covers is not permitted!
Danger of death!
Touching live terminals, cables or device parts can result in serious injury or
death!
Warning
Do not switch off devices, e.g. using a line supply isolating device (main
switch), before disabling the pulse inhibit (T 48) on the infeed/regenerative
feedback modules. Otherwise, the device can be destroyed along with other
devices in the control cabinet.
Warning
The rated current of the connected motor must match the rated converter
current. If this is not the case, then the protection of the motor cables is no
longer guaranteed. The cross–section of the motor feeder cable must be
dimensioned for the rated drive converter current. If this is not carefully
observed, cables can overheat and can even cause an equipment fire.
Caution
When using mobile radios (e.g. cellular phones, mobile phones, 2–way radios)
with a transmission power of > 1 W close to the equipment (< 1.5 m) the
function of the equipment can be disturbed.
Note
This device/module is an open–type device corresponding to UK 50 and, thus,
may only be operated in enclosures/cabinets that ensure protection against
mechanical damage. To ensure protection against mechanical damage, the
devices may only be operated in enclosures/cabinets with degree of protection
IP54 in accordance with EN 60529.
