The standard mandates insulation of terminals and connections. Live parts must be protected against accidental contact using covers or IP (Ingress Protection) rated enclosures.
Stationary batteries cannot simply be placed anywhere; their physical layout determines risk mitigation. The standard defines precise layout classes: EN IEC 62485-2:2018 - Stationary batteries - iTeh Standards
IEC 62485-2 is an international standard establishing safety requirements for stationary secondary batteries, covering installation, ventilation, and protective measures against electric shock or electrolyte leakage. The standard applies to lead-acid and NiCd/NiMH systems with up to 1,500 V DC, crucial for applications like UPS, telecommunications, and solar energy storage. For more technical details, visit IEC .

The standard mandates that ventilation must keep hydrogen concentration , and ideally below 25% of the lower explosive limit (i.e., below 1% by volume). The required air change rate can be calculated using either:
Handheld tools used inside the room must be insulated to prevent phase-to-phase short circuits. Marking and Signage The standard defines precise layout classes: EN IEC
