Product Precautions
PW482-S01 feeds the internal unit power bus through an exclusive connector and can form a dual-redundant supply pair when two modules are installed.
- Accepts 220 to 240 V AC input.
- Connects through the unit's exclusive power connector.
- Installs in supported FCU, FIO and optical repeater units.
- Supports a two-module dual-redundant power arrangement.
PW482-S01 should be matched to the documented system position, companion hardware and retained project configuration before the channel or station is returned to control.
Important Notice: Preserve the complete PW482-S01 identity and verify its documented electrical, network or signal response before release.
