3 Mounting and Installation
Danger!
Explosion hazard from damaged electronic components
Premature wear of electronic components in a device that was previously used in a general
electrical installation can cause sparks that can ignite the surrounding potentially explosive
atmosphere.
Never install devices that have already been operated in general electrical installations
in electrical installations used in combination with hazardous areas!
Danger!
Explosion hazard from pollution
An excessively polluted surface of the device can become conductive and consequently ignite
a surrounding potentially explosive atmosphere.
Ensure that you install the device only in environments with a pollution degree 2 or better
according to IEC/EN 60664–1.

Danger!
Danger to life from electric shock
Absent or insufficient insulation can result in electric shock.
Only connect supplies that provide protection against electric shock to power feed modules
(e. g. SELV or PELV).
Caution!
Property damage from use of isolators for Power Rail supply
Using the isolators for Power Rail supply can damage the isolators and make the Power Rail
fail.
Do not supply the Power Rail via isolators.
