Installation and commissioning
DANGER
Electric shock and risk of explosion
If the actuator has not been connected to the protective conductor system (PE), there is a risk of electric shocks caused by a live housing in a fault condition. If the actuator is not connected to the equipotential bonding (PA), there is a risk of electric shocks and explosion caused by static charging of the housing.
- Before starting up the actuator, make sure that it is correctly connected to the protective conductor system (PE) and the equipotential bonding (PA).
- Take measurements to verify the connection to the to the protective conductor system (PE) and to the equipotential bonding (PA).
DANGER
Risk of explosion
In explosive atmospheres, human error can result in an explosion.
- Make sure the type of actuator used meets your requirements for the explosion-protected area. You can find this information on the actuator label.
Ex…: ATEX Zone 1, 2, 21, 22;
Red…: ATEX Zone 2, 22;
In…: not suitable for the explosion-protected area! - As far as possible, avoid working in an explosive atmosphere.
- Disconnect the actuator from the power supply before carrying out any work on it in an explosive atmosphere.
- Make sure that installation and connection work is only carried out by appropriately trained skilled personnel.
- Always work adapted to the ambient conditions.
- Work in active potentially explosive atmospheres must be approved by the operating company.
DANGER
Risk of death due to electric shock and short circuit
Damage to the cabling or incorrect installation can result in an electric shock or short circuit and fire/explosion.
- Make sure the electrical connection and integration of the control unit are only carried out by appropriately trained specialist personnel.
- Please ensure the cables are laid without being damaged. Bear in mind external influences on the cables and use appropriate cable ducts or cable trays.
- Make sure the wiring is done correctly (see circuit diagrams).
- Before commissioning/starting up, make sure all cables and the drive are undamaged.
- Remember the five electrical safety rules:
Unlock
Prevent it being switched back on
Ensure no voltage at all
Earth and short-circuit
Cover or block off adjacent parts that are still live.
CAUTION
Possible damage to musculoskeletal system
Working in positions with an adverse body posture can result in orthopaedic injuries.
- Make sure you are working as ergonomically as possible.
- Use appropriate tools, e.g. steps for easy access.
- Wear personal protective equipment: headgear and gloves.
CAUTION
Impact and tripping hazard
If the drive is not positioned carefully, it can pose an impact and tripping hazard.
- As far as possible, avoid installing the drive in the area of footpaths or work areas.
- Position the drive so that it does not cause any risk of tripping or head impact.
- If necessary, provide warning indicators or padding around any potential impact points.
WARNING
Risk of crushing and impact
If the actuator starts up unexpectedly, crushing injuries can occur at the connected assemblies.
- Potential crushing points should be considered in the integrator’s risk assessment.
- Check whether additional protective measures are necessary.
- Before beginning work on the actuator, make sure it is completely disconnected from the power supply to prevent an unexpected start-up.
- Make sure the actuator is assembled correctly.
- Check that the actuator fits on the fitting.
WARNING
Danger due to incorrectly integrated drives
- Hazards caused by the drive must be taken into account in your risk assessment for the complete machine. Bear in mind any crushing points associated with your installation setting.
- Only use the drive as intended in accordance with these installation instructions.
- Make sure that the drive meets your requirements:
ambient conditions such as temperature, atmosphere, protection against corrosion;
drive torque;
necessary travel speeds/runtimes;
reset function;
activation;
achievable reliability in implementing safety functions;
logic of the safety function: safe status in the event of a drop in voltage via reset mechanism.
DANGER
Risk to life and risk of property damage due to incorrect electrical connection
If inputs 1 to 5 of the multi-turn actuator are connected to different supply voltages, there is a risk of electric shocks and of serious damage to the multi-turn actuator.
- Connect inputs 1 to 5 of the multi-turn actuator to a uniform supply voltage.
- Note the bridges between the inputs drawn on the connection diagrams.
WARNING
Risk of crushing and impact
In the event of a power outage, the rotary drives with spring-return mechanism will return suddenly to their initial position. This can result in crushing or impact injuries if work is being carried out on the rotary drive and its connected assemblies at this time.
- Disconnect the power to the rotary drive before starting work. Make sure that nobody is working on the rotary drive or the connected assemblies (e.g. ventilation flaps) at this time.
- Only carry out work when the rotary drive spring is not under tension and is in its initial position.
WARNING
Risk of crushing and impact
If the Allen key is inserted, this can result in crushing and impact injuries in the event of unexpected start-up of the drive.
- Before starting work, disconnect the drive from the power supply to prevent an unexpected start-up.
- Remove the Allen key immediately after use.
WARNING
Risk of impact
If the drive falls wile work is being carried out, it can hit and injure someone.
- During installation and when dismantling, make sure nobody is located below you.
- During the installation, make sure that the drive cannot loosen or detach itself. The same applies over longer periods, taking into account external influences such as vibration, corrosion etc.
WARNING
Finger twisting
At the open end of the shaft, there can be unexpected rotational movements, e.g. if the rotary drive is accidentally switched on or if the return spring is triggered by a power outage.
- Never stick your fingers into the open end of the shaft.
- Only operate the rotary drive once it is installed.
- Turn off the power to the rotary drive before starting work to avoid it being started unexpectedly.
Comply with any applicable national and international standards and regulations for Ex areas. Certified equipment must be installed in accordance with the manufacturer’s instructions. If you use the device in a manner that contravenes that stipulated by the manufacturer, this can impair the safety level of the device. For project planning, selecting and installing electrical systems, EN/IEC 60079-14 can be consulted. An Ex e terminal box (e.g. ExBox-...) must be used for the electrical connection.
- Lay the connection cables securely and so they are adequately protected against physical or thermal damage.
- Put in place a potential equalisation mechanism.
- Avoid temperature transfer from the fitting to the drive unit.
