1.6.1
Access restriction
The modules are open operating equipment and must only be installed in electrical equipment
rooms, cabinets, or housings.

Electrical installation
Observe the regional safety regulations.
TB20 devices can be equipped with modules that can carry dangerously high voltages. The voltages
connected to the TB20 devices can result in hazards during work on the TB20 devices.
1.6.3
Protection against electrostatic discharges
To prevent damage through electrostatic discharges, the following safety measures are to be followed
during assembly and service work:
Never place components and modules directly on plastic items (such as polystyrene, PE film) or in
their vicinity.
Before starting work, touch the grounded housing to discharge static electricity.
Only work with discharged tools.
Do not touch components and assemblies on contacts.
1.6.4
Overcurrent protection
To protect the TB20 and the supply line, a slow-blowing 8 A line protection fuse is required.

EMC protection
To ensure electromagnetic compatibility (EMC) in your control cabinets in electrically harsh
environments, the known rules of EMC-compliant configuration are to be observed in the design and
construction.
