®
Warnings
• Do not sideload the actuator
• Only use the actuator within specified working limits
• When mounting the LA20 in the application ensure that the bolts can withstand the wear and they are secured safely
• Motor type G and B must only be used with their respective control box types .
• Motor type B: motor which must be used with COBO, CBJC, CBJ1, CBJ2, CBJH or generally in applications that are mainly battery driven or customers'
own control box .
• Motor type G: motor which must be used with CO61, CO71, CO41, CA30/40 .
• Instruction concerning the turning of the piston rod eye: When mounting and taking into use, it is not permitted
to make excessive turns of the piston rod eye . In cases where the eye is not positioned correctly, it is permitted
to first screw the eye down to its bottom position, at a maximum torque of 2 Nm (1), and thereafter a
maximum half turn outwards again (2) .
• If an actuator with stroke length below 50 mm is used, and the electrical endstop switch fails, be aware that the distance before reaching the
mechanical endstop will be prolonged .
The extra distance will be 50 mm minus the actual stroke length .
This means that an actuator with 20 mm stroke length will travel an additional 30 mm before reaching the mechanical endstop if the switch fails .
Recommendations
• Do not place load on the actuator housing and do prevent impact or blows or any other form of stress to the housing
• Connection bolts must be dimensioned so that they have the necessary strength and tolerance in order to obtain the minimum safety factor according
to the requirements of the authorities
• Ensure that the cable lock is mounted correctly
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress
• Only use the actuator within the specifications
• Connection bolts and brackets are to be inspected in connection with service and must be replaced if there are signs of wear
• The product must always have the motor short circuited to obtain self-locking according to label value/rated value
• Ensure that the duty cycles and the usage temperatures for LA20 actuators are respected
• The LA20 is not suitable for use in outdoor applications where it can be exposed to sun and rain .
• Do not expose the actuator to pull during transport of the application
Cable mounting
A: To mount a cable
Step 1:
Place the cable in the actuator

Step 2:
Press the cable lock down into place
LA20 is a slim inline actuator created to cover a wide range of applications, where
design, size and power are crucial . The combination of a high lifting capacity of 2,500 N
with its robust but stylish, small form factor makes the LA20 the ideal solution for many
of today's demanding applications .
