Click on the questions to view answer The AVS30 has a fuse. How does this work?
If the AVS30 fuse blows (MOV gives a momentary short and therefore takes out the fuse) due to a transient. Then the AVS will not work and LED’s will extinguish i.e the unit will appear dead. Replace the fuse with a new 0.5A HBC Ceramic, antisurge 20x5mm. This fuse in addition to a spike protection […]
Does the AVS30 have an intelligent time delay?
Yes, the AVS30 does have an intelligent time delay.
Is the time delay on the AVS30 constant on all units?
The time delay at manufacturing is not set identically on all AVS30 units. This will allow units to start at slightly different delay. So if multiple Sollatek units are protecting multiple loads (like Air conditioners), when the power returns to normal after a power cut, not all A/Cs start at exactly the same time. This […]
Is the AVS30 suitable for "Mobile Installation" into Caravans and Motorhomes.
The AVS30 has common neutral and a common earth for  input and output. This is more related to the general wiring system classification of earthing of which we do not advise as this info is detailed in the IEE regs (section 708). The AVS is single phase L-N-E connection and therefore suitable for caravan and […]
Which fuse should I use in the Sollatek AVS30 If I need to replace it. The manual states 0.5A but the unit has a 5Amp when bought new?
The fuse should be the following type: 5.0A HBC Anti Surge 20x5mm. This is a product upgrade and now standard in all new AVS units

All questions Would it matter if live and neutral were swapped?
Yes. AVS/AVR  input and output switches (where fitted) are connected in series with the Live wire. It is important to ensure the live can be isolated via a switch. A reversed supply would have its neutral switched which will keep the live  cable energised and contravene safety regulations (earth bond touch voltage issues)
