Schneider Electric

Schneider Electric — field brand hub

Schneider EVlink / EVinox-class AC chargers show up on commercial and workplace Level 2 installs. Ownership is the wallbox/pedestal: ground-fault path, phase config on 3P, LED status logic, and max-current commissioning — not a DC power cabinet. Always verify nameplate and breaker before calling OEM for “no power.”

When this OEM shows up

Common tickets: ground fault, missing phase on 3P installs, LED stuck red, wrong max current after config/commissioning. Unit owns GF sensing, local controller, and config. Electrician owns phases/PE/breaker. Network/ops owns OCPP mapping and remote config drift after fleet updates.

How faults present

• LED status: stuck red / fault indication with or without OCPP Faulted.
• OCPP/CSMS (networked): Faulted, Unavailable, or Available but capped amps. Faulted triage: /guides/ocpp-faulted-triage.
• Local config UI/tools: max current and phase settings often explain “slow” or “won’t start” without a protective trip.
• Physical: missing phase after panel work, moisture at glands, incorrect DIP/config after board swap.

Ranked failure patterns

1. EVlink ground fault — Moisture or true PE/GF path. Entry: /entries/schneider-sch-ev-gf-evlink-ground-fault. PE: /entries/protocol-gnd-01-ground-continuity-fail-at-dispenser.

2. Missing phase on 3P install — Upstream or miswired phase; measure before board swap. Entry: /entries/schneider-sch-ev-phase-missing-phase-on-3p-install. PQ: /guides/site-power-quality-basics.

3. Wrong max current config — Commissioned below breaker/cable capability or left at default. Entry: /entries/schneider-sch-ev-cfg-wrong-max-current-config. Related load-management confusion: /entries/protocol-load-01-dynamic-load-management-caps-to-0-a.

4. LED status stuck red — Latched fault or UI/LED board; pull OCPP/vendor code before reset loops. Entry: /entries/schneider-sch-ev-hmi-led-status-stuck-red. Related: /entries/protocol-ocpp-f01-statusnotification-stuck-faulted-after-reboot.

Logs / tools

Config screenshots (max A, phase mode), LED photos, DMM on L1/L2/L3/N/PE, CSMS StatusNotification, IR if thermal complaint.

Escalate when

• Electrician: Missing phase, PE/GF wiring, breaker mismatch.
• Network/ops: OCPP mapping; remote config drift after fleet updates.
• OEM: Confirmed GF hardware or LED/controller after supply and config verified.

Do not OEM-escalate wrong max-current settings or single-phase loss that is upstream.

Field checklist

1. Measure L1/L2/L3/N/PE before any board swap on 3P installs.
2. Photo LED state and export CSMS StatusNotification if networked.
3. Screenshot max-current and phase-mode config vs breaker rating.
4. If ground fault: dry, inspect glands, verify PE continuity.
5. If LED stuck red: capture vendor/OCPP code once — avoid reset loops.
6. If “slow charge”: confirm config amps and any LMS cap before OEM.
7. Match nameplate current to feeder before calling the unit dead.

Wrong max-current after commissioning is a config ticket, not an OEM failure. Upstream missing phase is electrician work (/guides/site-power-quality-basics).
