Multiple Choice

At the top of the enclosure there are how many connectors for which cabling?

Explanation:
Four connectors at the top are allocated for power and alarm cabling, typically two for power and two for alarm. This setup keeps the critical power and alarm circuits separate and ensures reliable operation: power cables feed the unit while alarm lines drive local indicators and remote monitoring, with enough junctions to handle redundancy or multiple alarm devices. Other arrangements would either reduce the number of needed connections or mix data-related wiring with power/alarm, which isn’t how these enclosures are wired for safety-critical functions.
