Battery connector	Internal Li-ion battery backup (JST connector)

Wiring is for a qualified installer

Relay outputs can switch mains voltage. Power should be fully disconnected before wiring, and installation should be carried out by a qualified electrician.

Power

The unit runs from a 12VDC supply connected to the power screw terminals. An internal Li-ion battery (connected via the JST battery connector) can keep the unit running through a mains power interruption — the dashboard reports both battery level and whether DC power is present.

The relays

The unit has 6 relay outputs, each rated 10A @ 250VAC / 10A @ 30VDC, wired via COM / NO / NC terminals. On the OLED screen and in the dashboard, relays are numbered 1–6.

Relays are switched from the CoppelBox dashboard (or by automation/schedules configured there) — the unit's front-panel buttons don't turn relays on or off directly. See the User Guide for controlling relays from the dashboard, and The OLED Screen for what the relay indicators on the screen mean.
