Page 3: Safety Instructions
1. Safety instructions Please read the operating manual carefully before you start with commissioning. Consider the JS-Technik following warnings avoid personnel injuries machinery failures. GmbH assumes no responsibility or guarantee for damage and consequential damage caused by failure to observe the operating instructions. 1.1. -
Page 4: Mechanical Movement
DANGER Motor restart If the control voltage is applied or the speed setpoint is stored, the motor restarts automatically after a power failure. 1.5. Mechanical movement Body parts which come into contact with rotating parts, can be injured. Clothes, jewellery, and similar objects can be caught and pulled into the motor. -
Page 5: Unauthorized Usage
Unauthorised usage 2.1. In particular, the following uses of motors are prohibited and can lead to machinery failure: • Operating the motor with imbalance, for example, caused by dust deposits or icing. • Resonance operation, operation with strong vibrations, transmitted from the environment to the motor. -
Page 6: Electrical Connection
• Ensure even support, precise alignment in case of direct coupling and use of thread sizes specified in EN 50347 for motor feet and flange mounting. • Provide a vibration-free environment. Avoid build-up resonances with rotation frequency and the double frequency of the power supply. •... -
Page 7: Connection Of Lead Out Cables
The connection must be made in such a way that a permanently secure electrical connection is maintained (no protruding wire ends). Suitable cable lugs must be used for the connections of all main cables. A safe protective conductor connection must be made. Tightening torques can be found in Table 2. -
