Lee from United Kingdom asks

I’m wondering if this comes with a wiring diagram. We will be deploying one of these for every two server cabinets in a server farm. As this is a 4 pole isolator it is likely that there are a number of terminals (L1-L3 on top and T1-T3 on the bottom with earth terminals present too). Each of these isolators with be connected to a double gang standard (U.K) plug socket with a fused PSU (one power supply unit running the equipment in each server cabinet). The supply to the isolator will be single phase 2.5mm Twin and Earth. Can you please specify when using 2.5mm Twin and Earth for the load and supply which terminal are for live, neutral and earth? Many thanks in advance.

Hello, unfortunately, there is no wiring diagram available from the manufacturer, however, we have uploaded a photo of the terminals, and the manufacturer has provided wiring instructions as follows: The top side is the Mains in and the bottom is the Load side. To wire it up, you will connect your mains live wire to either L1, L2, or L3, depending on need and your load live to T1, T2, and T3, depending on need. If you wish to have the Neutral switched as well, connect it to the Neutral Terminal next to the Lives. If you don't need it, connect the Neutral to the left terminal as seen in the photo. Connect the earth wire to the Earth terminal on the right side as in the photo.
