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 device 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 device contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must
therefore be avoided.
Breaking the sealing tape on the upper handle of the device will result
in loss of guarantee and proper operation will no longer be insured.
