4 Installation and maintenance
Installation precautions
Mount the unit on a 35 mm DIN rail. Attach all the cables to the connection block. Use max 1 Nm tightening torque.
Warning!
All the safety functions must be tested before starting up the system.
Bypassing of Eden and Tina units
If one or more Eden or Tina units are bypassed by a Tina 5A, a diode such as a 1N4007 must be inserted
with forward current out from pin-4 of the last bypassed unit.
If one or more Eden or Tina units bypass each other, a diode such as a 1N4007 must be inserted with
forward current out from pin-4 of the last unit in both bypassing circuits (excerpt from connection example
HD3801A in the Safety Handbook below).
Maintenance
Warning!
The safety functions and the mechanics shall be tested regularly, at least once every year to confirm that all the
safety functions are working properly (EN 62061:2005).
In case of breakdown or damage to the product, contact the nearest ABB/Jokab Safety Service Office or reseller.
Do not try to repair the product yourself since it may accidentally cause permanent damage to the product,
impairing the safety of the device which in turn could lead to serious injury to personnel.
