Disconnecting device and cables

The device does not have its own off switch and must be operated by the customer
via a disconnecting device and current limiting device (or combination of both) to
comply with ISO / IEC60079-14 and ISO / IEC61010-1.
An example of such a disconnecting device, which is not included in the scope of
supply, is a C 4A circuit breaker, which must be installed near the Q2 for reasons of
explosion protection and electrical safety.
The disconnect device must meet the requirements of the installation site, must be
capable of safely disconnecting at least 48 V DC, and must disconnect all power
supply lines leading into the hazardous area. It thus contributes to the formation of
the power-limited circuit.
