Safety information

Dangerous voltages can occur on the connectors, even though the
! auxiliary voltage has been disconnected.
National and local electrical safety regulations must always be
followed.
The device contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must
therefore be avoided.
The frame of the device has to be carefully earthed.
Only a competent electrician is allowed to carry out the electrical
installation.
Non-observance can result in death, personal injury or substantial
property damage.
Breaking the sealing tape on the rear panel of the device will result in
loss of warranty and proper operation will no longer be guaranteed.
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.
