September 7, 2021

Electrical Enclosure with Incoming 3-Phase 480V AC Power

Situation

Worker approaches the enclosure and the disconnect switch for the 480V power source is in the OFF position. The disconnect switch has failed with one phase (L1) in the closed position (L2, L3 are open). The ground leads of the devices are NOT connected to ground because of an improper installation or termination failure.

The worker applies a lock. Following safety procedures, the worker performs an absence of voltage test with the electrical enclosure closed using a permanently mounted device.

To Improve Cybersecurity, Don’t Wait on Firmware and Software Updates

One of the key ways to help protect your organization against nefarious actors and cyberattacks is proactive firmware and software management. Keeping your firmware and software up to date isn’t a one-off exercise. It’s a process. And manufacturers are well advised to adopt version updates as they become available. Especially as more manufacturers implement digital strategies to improve operational efficiency, reveal data-driven insights, and use cloud-based technologies.

What Does Smart Enclosure Climate Control Look Like?

The modern manufacturing industry is adopting smart technology solutions to drive performance and increase efficiency. These kinds of smart systems help alleviate a variety of pain points, like time-consuming, manual tasks and the lack of real-time data in order to optimize production programs. These principles certainly apply to smart industrial enclosure climate control systems, but there’s more to smart enclosure cooling than just automating tasks or streamlining workflows.
