Battery connection: energy sources and direct controls

Connecting batteries works directly on terminals that cannot be de-energised, with arc and chemical exposure.

High-energy check

Treat battery connection as high energy at all times. Stored energy is present even when everything is switched off.

This task's main energy sources are not calculated by this tool. Use the trigger checks below and competent-person verification.

Trigger checks

Electrical
Current, voltage, energisation, arc flash or stored electrical energy.
Chemical
Harmful, reactive, flammable, corrosive or toxic substances.
Thermal
Heat, cold, flame, steam, sparks or thermal stress.
Battery systems
Battery strings cannot be switched off. Stored electrical energy, arc potential and chemical exposure are present at all times, and thermal runaway can propagate once started.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

Only authorised persons carry out connection work.
Insulated tools and task PPE are used at all times.
Connection sequence is written and followed step by step.
Metal items and uninsulated tools are excluded from the work area.
Emergency arrangements for arc and chemical exposure are in place.
Stop if any step in the sequence cannot be verified.

For your SPA or pre-start

State the insulated tool and PPE requirement, the connection sequence, how tools and metal items are controlled and who supervises the work.
