When you supply the module in the non-intrinsically safe version with low voltage, you must
be sure to observe the following safety rules before starting work on the device:
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.
