Gallagher M35 mains electric fence energiser - 230Volt | ST | FAQs
How do I install and earth an M energiser correctly and how many earth rods?
Mount the unit under cover near a mains outlet, then build a solid earth system, the most common cause of low fence voltage is poor earthing. Typical installs use multiple 1m earth rods, driven into permanently damp soil and spaced well apart.
All M‑range energisers include lightning protection as standard, and www.daltonsupplies.com also offers add‑on lightning diverters if you want extra surge defence on long lines.
What's the real difference between the standard M models and the i-Series like the M5000i?
The standard M models are all about being tough and easy to use, with built-in lightning protection, LEDs, and a simple setup, perfect if you just want dependable power for your fence. On the other hand, the i-Series (like the M5000i) come with a weatherproof external display, adaptive output, and you can add a Wi-Fi Gateway plus an app for instant alerts. They also work with fence monitors to help zone in on faults, which is handy for bigger, more complicated setups.
Which M‑series model should I choose for my fence length and animals?
Gallagher’s M‑range spans small paddock units like M120/M160 up to higher‑output units such as M650/M950/M1400, plus the smart M5000i at the top end. As a very rough guide based on multi‑wire and ideal conditions:
M120 up to 8km; hobby/small paddocks
M160 up to 9km; still small runs but a step up in stored energy
M350/M550/M650 up to 28/35/40km; suit mixed livestock and longer perimeter lines
M950/M1400 up to 42/55km; higher load/vegetation and larger blocks
M5000i (i‑Series) up to 100km and adds smart diagnostics/monitoring
