How do I protect an ATM from lightning?
Short answer: Protect an ATM from lightning by using surge protection on both the power line and the communication line, because a surge through either can destroy the modem or main board. Central Florida is one of the most lightning-active regions in the U.S., so surge protection is essential for every ATM here.
The Central Florida Angle
Central Florida’s summer storm pattern is famously regular — clear mornings, then thunderstorms most afternoons from June through September.
- Power customers of Duke Energy, OUC, Winter Park Electric, KUA and Ocala Electric all see storm-related blips.
- Surges can travel through phone and Ethernet lines, not just power.
- A UPS lets the ATM shut down cleanly instead of crashing mid-transaction.
Is a regular power strip enough?
No. Use a quality surge protector rated for electronics, and protect the communication line too.
What to Install
- Surge protector rated for electronics on the power line
- Surge protection on the phone or Ethernet line if used
- Proper grounding of the outlet
- Consider a UPS (battery backup) for clean shutdowns
Signs of Surge Damage
- ATM won’t power on after a storm
- Modem lights off or blinking abnormally
- Communication errors after storms
- Burnt smell — unplug immediately and call a technician
