- Do not plug/unplug encoder cables and control terminal blocks under live power, which may damage communication chips of interfaces.
- PE terminal shall never be connected to grid neutral wire; it must be separately wired to equipment protective earth bar.
- Do not touch main circuit terminals within 5 minutes after power-off, as DC bus capacitors store high residual voltage.
