7 Requirements to be met by installation

7.1 Instructions on installation of safety equipment

 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 pos-
sibilities:
 The conductor is installed permanently and in example protected against external damage
with a cable duct or reinforcement.
 Single multi-conductors are used.
 The conductors are situated in an electrical cabinet.
 The conductors are shielded independently and have grounding.
 If applicable, the requirements of EN 60204-1 have to be considered to install the connectors
correctly.
 Protection against dirt is ensured if the frequency inverter and safety control equipment is in-
stalled 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 (suspended loads) or
round axes with asymmetrical weight distribution, mechanical brakes must be installed addi-
tionally.
 Only use voltage sources with safe disconnection (SELV/PELV) according to VDE0100. Comply
with the specifications in chapter 7.3 .
 The STO inputs may be controlled with pulsed signals, neg. Pulse lengths < 500 s.
 Errors can be excluded in the case of the Agile units because the terminal blocks for the STO
function are physically separate from one another. The signal cables between the safety con-
trol equipment and ACTIVE Cube must either be physically separate from one another or suit-
able, 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 acceptance 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 the input current according to the operating
instructions is available for each of the inputs STOA and STOB (typical: 10 mA). If more than one Agile
frequency inverters are connected to one safety control device, the safety control device must provide
sufficient power for all of them.

7.2 External Safety Control Equipment

Safety control equipment, upon request (e.g. actuation of emergency stop or access to hazard area,
must trigger appropriate responses in order to protect people, the machine and the environment. They
evaluate sensor signals or safely switch off dangerous states.
External safety control devices must meet the following requirements:
 External safety control equipment and safety modules for control of the digital inputs (STO)
must meet one of the following classifications, to meet the classification of the AGL device:
 PL d according to EN ISO 13849-1
 SIL 2 according to IEC 61508

the whole installation meets these requirements.
 The switching capacity of the safety control equipment must be designed for the maximum
permissible, limited output current of the DC 24 power supply. Comply with the instructions of
the manufacturer of the safety control equipment on the permissible contact load and any
safeguards to be provided for the safety contacts.
 The emergency stop device must comply with Standard EN ISO 13850.
 If a safety request (e.g. emergency stop actuated or sensor signals that safety door is open)
is reset (emergency stop unlocked, safety door closed) this alone shall not result in a restart
of the drive. Restart may only occur after the safety control device has been reset.
External safety control devices evaluate sensors:
