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 trained and qualified persons are allowed to connect and operate BIO-Tester Relion REX640.
National and local electrical safety regulations must always be followed.
The necessary and required earthing connections must be made according to the product guidelines and regulations.
When the withdrawable module 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.
