General
3.1
Proper Use
Power electronics models EAN823, EBN853 and EBN861 are to be used exlusively for triggering elek-
trical actuators of the PME120, LME 620, RSD... or RHD... series. Do not use them for any other pur-
pose. Otherwise, a hazard of personal injury or of damage to or impairment of the operational reliability
of the device may arise.
3.2
Safety and Precautions
When mounting the electronics in areas which may be accessed by unauthorized persons, take the re-
quired protective measures.
- Only qualified specialists who have been trained for these tasks are authorized to mount and adjust
the electronics, and to make the electrical connection.
- When working on the electronics always observe the locally valid accident prevention regulations
and the regulations concerning the construction of technical installations.
- Switch-off the voltage supply; make sure that unintentional switching on is not possible
- Make sure that cutting off the voltage supply does not affect the plant process
- Consider restoring process forces from the final control element when cutting off the voltage
4.
Storage
The devices may be stored under moist and aggressive condition for a short time. The equipment is
protected against external corrosive influences. However, direct exposure to rain, snow, etc. must be
avoided
Condensation may occur in the terminal box. Therefore, it is protected by a desiccant, which ensures
sufficient protection for approximately 150 days. The desiccant can be regenerated at a temperature of
90° C within 4 h.
The desiccant must be removed prior to commissioning the electronics.
4.1
Long-time Storage
If you intend to store or transport the device for a longer time, we recommend to wrap it in plastic foil
and add desiccant. Regularly check if the desiccant is still active.
