- The utilization implies knowledge of and compliance with following standards:
EN ISO 13849-1, EN 62061, EN 60204-1, EN ISO 12100.
- In the risk analysis, take into account that in manual start mode a possible sticking of
the start button can lead to an immediate activation of the module.
- If expansion modules or external contactors are used, make sure that they have
forcibly guided contacts and connect in feedback an NC contact of each device.
7.6 Limits of use
- Use the device following the instructions, complying with its operation limits and the
standards in force.
- The devices have specific application limits (min. and max. ambient temperature,
maximum currents, IP protection degree, etc.) These limitations are met by the device
only if considered individually and not as combined with each other.
- According to EU directives, this device is not intended for private use.
- The manufacturer’s liability is to be excluded in the following cases:
1) Use not conforming to the intended purpose.
2) Failure to adhere to these instructions or regulations in force.
