DANGER
Supply with hazardous voltage
If you connect the switching contacts of the 6DR4004-8K module to a hazardous voltage,
observe the following safety rules:
1. Isolate the device from power. Use a circuit breaker positioned near the device to do this.
2. Make sure that the device cannot be switched back on inadvertently.
3. Make sure the device is truly isolated from power.
CAUTION
Maximum AC/DC switching voltage with UL approval E344532
Mechanic Limit Switches (MLS) 6DR4004-6K/-8K
are approved for use with positioners with UL
approval. The maximum switching voltage in this case is ≤ 30 V AC/DC.
If switching voltages greater than 30 V are connected, the UL approval for the positioner
becomes invalid.
