Safety information
Dangerous voltages can occur on the connectors, even though the
auxiliary voltage has been disconnected.
Non-observance can result in death, personal injury or substantial
property damage.
Only a competent electrician is allowed to carry out the electrical
installation.
National and local electrical safety regulations must always be
followed.
The frames of the IED and of the HMI have to be carefully earthed.
When the plug-in unit has been detached from the docking unit, do
not touch the inside of the DU. The IED DU internals may contain
high voltage potential and touching these may cause personal injury.
The IED contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must
therefore be avoided.
Whenever changes are made in the IED, measures should be taken
to avoid inadvertent tripping.
