  • Page 4: Preface

    This user manual does not address the end-user, but is intended as a source of information for the manufacturer of the equipment or system only, and it will tell you how to install, use and maintain your LINAK electronics. It is the responsibility of the manufacturer of the end-use product to provide a User Manual where relevant safety information from this manual is passed on to the end-user.

  • Page 5: Linak Application Policy

    LINAK shall be responsible solely that LINAK products comply with the specifications set out by LINAK and it shall be the responsibility of the LINAK customer to ensure that the specific LINAK product can be used for the application in question.

  • Page 6: Safety Instructions

    Chapter 1 Safety instructions Please read this safety information carefully: Be aware of the following three symbols throughout the user manual: Warning! Failing to follow these instructions can cause accidents resulting in serious personal injury. Recommendations Failing to follow these instructions can result in the actuator suffering damage or being ruined. Additional information Usage tips or additional information that is important in connection with the use of the actuator.
  • Page 7 Ensure that the cable cover is mounted correctly. Use 1.5Nm torque. • Ensure that the duty cycle and the usage temperatures for LA12 actuators are respected. • Ensure that the cable cannot be squeezed, pulled or subjected to any other stress.

  • Page 8: Mounting Guidelines

    Please pay special attention to the area around the housing where parts can be trapped and cause damage to the application and actuator. In applications with high dynamic forces LINAK recommends not to use the fully extended or retracted position over longer time, as this can damage the endstop system permanently.
  • Page 9 It is the application manufacturer’s responsibility to incorporate a suitable safety arrangement, which will prevent personal injury from occurring, if the actuator should fail. Warning! LINAK’s actuators are not designed for use within the following fields: • Offshore installations • Explosive environments •...

  • Page 10: Electrical Installation

    Electrical installation • To ensure maximum self-locking ability, please be sure that the motor is shorted when stopped. Actuators with integrated controller provide this feature, as long as the actuator is powered. • When using soft stop on a DC-motor, a short peak of higher voltage will be sent back towards the power supply.
