Requirements for the installation

• The components must be protected against conductive dirt, e.g. by installing them in a control cabinet with degree of protection IP54 in accordance with IEC 60529.
• Assuming that the presence of conductive dirt can be excluded at the installation site, a control cabinet with a correspondingly lower degree of protection is also permitted if in accordance with the applicable standards (e.g. EN 60204‑1).
• The wiring technology used must comply with the standard EN 60204-1.
• Use conductor end sleeves to exclude a short circuit to adjacent signals.
• The STO control cables must be routed according to EMC guidelines and as follows:
• Outside a closed installation space: Shielded cables must be routed permanently (fixed) and protected against external damage, or equivalent measures must be taken. The maximum cable length of 100 m must not be exceeded.
• Adhere to the regulations in force for the application.
• You must use suitable measures to ensure that STO control cables are routed separately from the power lines of the drive.
• The STO function does not detect short circuits or interference voltage in the supply line, so you must ensure the following:
• No parasitic voltages can occur in the STO control cables
• The external safety controller can detect a crossfault from an external potential to the STO control cables
• Observe without fail the values specified for safety components when designing the safety circuits.
• The STO signal (STO_1+, STO_2+) must not be used for feedback.
• For a safety controller/safety relay, you must only use grounded voltage sources with protective electrical separation (PELV) in accordance with EN 61131-2 and EN 60204-1.
• If several voltage sources are used, each voltage source must be connected to a PE system.
• When planning the installation, observe the technical data of the device.
• For safety-related applications with the device, the jumpers at the STO input X6 must be removed.
