Transport and storage
Carefully inspect for shipping damage. Damage to the shipping carton is usually a good indication that
it has received rough handling. Report all damage immediately to the freight carrier and your ABB rep-
resentative. Verify that the items on the packing list or bill of lading agree with your own.
Contrac actuators may be stored under moist and aggressive condition for a short time. The equip-
ment is protected against external corrosive influences. However, direct exposure to rain, snow, etc.
must be avoided.
Actuators, equipped with an anti condensation heater, are additionally protected by desiccant placed
in the connector (and in the terminal box of the separate electronics, if present). The desiccant guar-
antees sufficient protection for approximately 150 days. It can be regenerated at a temperature of 90°
C within 4 h.
The desiccant must be removed prior to commissioning the actuator or the electronics
2.4
Proper use
Control actuators are intended to be used exclusively for actuating final control elements (valves,
vanes, etc.). Do not use these actuators for any other purpose. Otherwise, a hazard of personal injury
or of damage to or impairment of the operational reliability of the device may arise.
2.5
Safety and precautions
When mounting the actuator in areas which may be accessed by unauthorized persons, take the re-
quired protective measures.
- Control actuators perform movements for positioning vanes and valves. Handle properly and with
care. Otherwise, a hazard of bruise injuries may arise.
- When changing the oil of the actuator, thoroughly remove any oil that may have run down on the
floor during the procedure to avoid accidents.
- Dispose of the waste oil in compliance with the respective local regulations. Make sure that no
waste oil reaches the water cycle.
- Only qualified specialists who have been trained for these tasks are authorized to mount and adjust
the control actuator, and to make the electrical connection.
When working on the actuator itself or its electronics always observe the locally valid accident pre-
vention regulations and the regulations concerning the construction of technical installations.
2.6
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.
