WEEE directive 2002/96/EC. Proper disposal prevents negative effects on people and the environment, and supports the reuse of valuable raw materials. If it is not possible to dispose of old equipment properly, ABB Service can accept and dispose of returns for a fee. -
Page 9: Storage Conditions
Safety 1.11 Storage conditions The actuators may be stored under aggressive, moist conditions for a short time. The equipment is protected externally against corrosive influences. However, direct exposure to rain, snow, etc., must be avoided. The permissible storage and transport temperatures must be observed. Actuators equipped with an anti-condensation heater are additionally protected by desiccant, which is placed in the following locations where condensation may be a problem: Position sensor:... -
Page 10: Electrical Installation Safety Information
Safety 1.13 Electrical installation safety information The electrical connection may only be performed by authorized specialist personnel according to the electrical plans. Comply with electrical connection information in the manual. Otherwise, the electrical protection class can be affected. The secure separation of contact-dangerous electrical circuits is only guaranteed when the connected devices fulfil the requirements of the DIN EN 61140 (VDE 0140 Part 1) (basic requirements for secure separation). -

Page 19: Operation
Operation Operation Automatic / manual mode The servo motor triggered by the power electronics controls the axially fixed drive sleeve/nut assembly via grease-lubricated spur gears. A ball bearing screw (see Figure Fig. 12) radially fixed by an anti-twist arrester converts the rotary motion to a linear one. A position sensor detects the current thrust rod position via mechanical reduction gearing without backlash. -
Page 20: Maintenance
Maintenance Maintenance Important All maintenance activities may only be performed by properly qualified persons. Contrac actuators feature a robust construction. As a result, they are highly reliable and require minimal maintenance. The maintenance intervals depend upon the effective load and are therefore not specified here. -
