7.4 Wiring
Attention: Do not install the safety module if voltage is present. Power the device
only when the electrical circuits have been completely realized according to the speci-
fications indicated in the OPERATION paragraph. The first time you start the machine
ensure that there are no people close to hazardous areas.
- Check that the supply voltage is correct before powering the device.
- Keep the charge within the values specified in the electrical operation categories.
- Only connect and disconnect the device when the power is off.
- Discharge static electricity before handling the product by touching a metal mass
connected to earth. Any strong electrostatic discharge could damage the device.
- Power the safety module and the other devices connected to it from a single SELV
source and in accordance with the applicable standards (applies only to versions with
supply voltage 12 V and 24 V).
- Always connect the protection fuse (or equivalent device) in series with the power
supply for each device.
- Always connect the protection fuse (or equivalent device) in series to the safety
electrical contacts.
- During and after the installation do not pull the electrical cables connected to the
device. If excessive tension is applied to the cables, the device may be damaged.
7.5 Additional prescriptions for safety applications with operator protection
functions
Provided that all previous requirements for the devices are fulfilled, for installations
with operator protection function additional requirements must be observed.
- 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.
- 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.
3) Fitting operations not carried out by qualified and authorized personnel.
4) Omission of functional tests.
- For the cases listed below, before proceeding with the installation contact our as-
sistance service (see paragraph SUPPORT):
a) In nuclear power stations, trains, airplanes, cars, incinerators, medical devices or
any application where the safety of two or more persons depend on the correct opera-
tion of the device.
b) Applications not contemplated in this instruction manual.
8 MARKINGS
