Special safety instructions for the connector box

The safety instructions are designed to avert danger and must be followed during installation, commissioning, production, troubleshooting, maintenance and trial or test assemblies. The connector boxes of the AL225x series are not designed for stand-alone operation and are always installed in a machine or system. After installation, the documentation the documentation and the safety instructions provided by the machine manufacturer must be read and applied.

WARNING

Serious risk of injury through high electrical voltage!

  • Negligent, improper handling of the connector boxes and bypassing of the safety facilities of the system or machine may result in personal injury or death through electric shock.
  • When installing and working on the connector boxes, all machine components and assemblies MUST be de-energized and secured against unintentional restoration of electrical power.
  • The machine manufacturer must prepare a hazard analysis for the machine, and must take appropriate measures to ensure that unexpected movements cannot lead to injury to persons or to objects.
  • Power connections may be live, even if machine components don't move. Never undo the electrical connections to the motor when it is live. Under unfavorable conditions arcing may occur, resulting in injury and damage to contacts.
  • Disconnect the linear motor from the servo drive and secure it against reconnection before working on electrical parts with a voltage > 50 V.
  • Due to the DC link capacitors, the DC link contacts "ZK+ and ZK- (DC+ and DC-)" and "RB+ and RB-" may be subject to dangerous voltages exceeding 890VDC, even after the servo drive was disconnected from the mains supply. Wait 5 minutes for the AX5101 - AX5125 and AX520x; 15 minutes for the AX5140/AX5160/AX5172; 30 minutes for the AX5190/AX5191; 45 minutes for the AX5192/AX5193 after disconnecting, and measure the voltage at the DC links "ZK+ and ZK- (DC+ and DC-)". The device is safe once the voltage has fallen below 50 V.

WARNING

Risk of injury through failure of the drive system!

Electronic equipment is not fail-safe. The machine manufacturer is responsible for ensuring that the connected motors and the machine are brought into a safe state in the event of a fault in the drive system.

WARNING

Caution – Risk of injury through electric shock!

Remove the motor and feedback lines from the connector box to the servo drive when you open the connector box.

Special safety instructions for the connector box 1:

Selection of motor and feedback cables!

For connecting linear drives, we recommend drag chain-capable, highly dynamic motor and feedback cables.

Note

Danger for persons, the environment or equipment

  • Please read this manual carefully before using the connector boxes. Follow all safety instructions. Should anything be unclear, please contact the sales office for your area and refrain from any further work on the system.
  • Only well trained, qualified electricians with sound knowledge of drive equipment may work on the device.
