5.1
− If work is to be carried out on live components, it must be possible to disconnect
the machine from mains supply by means of a main switch.
− According to EN 61800-5-2 a fault exclusion can be considered with one of the
following possibilities:
− Protection against dirt is ensured if the ACTIVE Cube frequency inverters and
safety control equipment is installed in electrical cabinets with high IP protection,
e.g. IP 54.
− If external forces act on the drive axis, e.g. in the case of vertical axes (sus-
pended loads) or round axes with asymmetrical weight distribution, mechanical
brakes must be installed additionally.
− Only use voltage sources with safe disconnection (SELV/PELV) according to
VDE0100. Comply with the specifications in chapter 5.3.
− The ACTIVE Cube frequency inverters must not be supplied with pulsed signals.
Cross fault detection via pulsed signals cannot be used for this reason. Errors can
be excluded in the case of the ACTIVE Cube units because the terminal blocks for
the STO function are physically separate from one another. The signal cables be-
tween the safety control equipment and ACTIVE Cube must either be physically
separate from one another or suitable, cross fault proof cables.
− Comply with applicable EMC instructions mentioned in the operating instructions.
− After installation, check the safety function and error reaction and issue an ac-
ceptance report.
− Interrupting the STO signals prevents a start of the motor. According to
EN 60204-1, STO must not be released during an impending endangerment.
−
Also comply with the instructions on external safety control equipment.
− During commissioning, check the safety function.
Select the dimensions of the safety application such that 14 mA input current is avail-
able for each of the inputs STOA and STOB. If more than one ACTIVE Cube frequen-
cy inverters are connected to one safety control device, the safety control device
must provide sufficient power for all of them.

Instructions on installation of safety equipment

The conductor is installed permanently and in example protected
o
against external damage with a cable duct or reinforcement.
Single multi-conductors are used.
o
The conductors are situated in an electrical cabinet.
o
The conductors are shielded independently and have grounding.
o
If applicable, the requirements of EN 60204-1 have to be considered to
install the connectors correctly.
