1.2 Electrical safety

Direct/indirect contact Protection against direct and indirect contact according to VDE 0100 Part 410 must be

ensured for all components connected to the system. In the event of an error, parasitic

voltages must not occur (single-fault tolerance). This also applies to devices and

components with hazardous contact voltages that are permanently connected to the

network and/or diagnostic interfaces of the devices used.

This requirement can be met by:

– Using power supply units with safe isolation (PELV).

– Decoupling circuits, which are not PELV systems, using optocouplers, relays, and other

components, which meet the requirements of safe isolation.

Insulation rating When selecting the operating equipment, please take into consideration the contamination

and surge voltages, which may occur during operation.

The FL PN/PN SDIO-2TX/2TX safe PROFINET gateway is designed for surge voltage

category II (according to DIN EN 60664-1). If you expect surge voltages in the system,

which exceed the values defined in surge voltage category II, take into consideration

additional measures for voltage limitation.

WARNING: Hazardous body currents and the loss of functional safety

Disregarding instructions for electrical safety may result in hazardous body currents and

the loss of functional safety.

In order to ensure electrical safety, please observe the following points.

WARNING: Loss of electrical safety and the safety function when using unsuitable

power supplies

The FL PN/PN SDIO-2TX/2TX safe PROFINET gateway is designed exclusively for

protective extra-low voltage (PELV) operation according to EN 60204-1. Only PELV

according to the defined standard may be used for supply purposes.

The following applies to the network and the I/O devices used in it:

Only use power supply units that meet EN 61204 with safe isolation and PELV according

to EN 50178/VDE 0160 (PELV). This prevents short circuits between primary and

secondary sides.

Make sure that the output voltage of the power supply does not exceed 32 V even in the

event of an error.
