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 frame of the protection relay has to be carefully grounded.
When the plug-in unit has been detached from the case, do not touch the
inside of the case. The relay case internals may contain high voltage
potential and touching these may cause personal injury.
The protection relay contains components which are sensitive to
electrostatic discharge. Unnecessary touching of electronic components
must therefore be avoided.
Whenever changes are made in the protection relay, measures should be
taken to avoid inadvertent tripping.
