Has any of you experienced such maintenance work?

The device comes in two series. Some of these units share cabinets, controllers, and cards. In the case of stopping one series of equipment, people wonder whether it is risky to carry out maintenance on another series: for example, during maintenance it may be necessary to find spare cables, add new cables, or make connections (to the wires coming in from outside the junction boxes inside the panel).
Performing maintenance in public areas is risky... Isn’t that the case with chemicals? We used to have two sets of equipment controlled from a cabinet room; one set was in operation while the other was shut down for maintenance, including tasks such as cable replacement and adding additional components – all of these tasks were carried out by us. It’s better to be cautious; finding a construction team might be rather troublesome… after all, those construction teams don’t care about such things……
The configuration is unreasonable. Using a common control system for devices in different sections can cause many problems.
It’s okay; I do this often, especially when making adjustments in the later stages
The risk is high; it is recommended to shut down both series before carrying out maintenance tasks. Otherwise, if the operating series is accidentally shut down, it will cause problems.
A stop here could lead to a shutdown of the entire plant. So I feel the risk is very high. It’s not worth taking that risk. With wires, it’s useless to be careful; you have to look through a pile to find a spare one. Then it will have to be flipped

This poses a high risk, so protective measures must be taken, such as disabling interlocks and setting the valves to manual mode to prevent accidental operation during automatic processes.
That makes sense. But there are too many people who plan to take a detour.
It’s best to stop then; once a stop is caused by maintenance, it will be costly, and someone will have to take responsibility
If you’ve already decided it’s not possible, just let your supervisor know; I’ll reserve my opinion……
