For example, when starting via the on-site control panel, an approval signal from the control room is required; similarly, when starting using buttons in the control room, a second confirmation is needed. At the same time, it’s necessary to ensure that startup parameters such as lubricant levels and pressure at the pump’s inlet and outlet meet the required conditions. This aspect should be taken into consideration during the design phase.

By accidental startup, you mean a human-induced accidental start, right? For this kind of situation, a safety lock or cover is usually added to the start/stop switch.
