Introduction
The Xantrex Freedom Sequence Intelligent Power Manager is a fully
integrated power management system (sometimes referred to as EMS or
energy management system) that provides automatic power and load
management for use in recreational vehicles (RV) while receiving power
from a generator or shore power. The Freedom Sequence power manager
optimizes the available current capacity from an AC electrical source to
power as many connected AC loads as possible. It makes decisions on
which loads get power based on a priority base set by the installer

Standard Features
• Manage power for single or split-phase AC sources up to 50 amps
including 15-, 20-, 30-, and 50-amp shore and generator power
sources.
• Fully user configurable AC and DC load management system using
the Xanbus System Control Panel (SCP).
• Monitor current draw and On/Off status for each AC load circuit,
including the current draw from the main AC source (shore or
generator power).
• Has six AC relays (PN: 809-0912) or four AC relays (PN: 809-0913)
via the AC relay terminal blocks which can control AC load circuits
rated up to 15 amps each.
• Four DC relays (via the DC auxiliary connector port) which can
control external DC circuits based on Battery Voltage.
These four DC relays can also be used to control external AC circuits

, directly
accessible via the SCP.
• Sequential engaging of AC loads for generator soft-start that
eliminates heavy inrush demand.
• Seamless integration with Freedom SW Inverter/Chargers to provide
charger derating, automatic inverter assist, and auto-detect generator
run conditions and reset breaker rating from Shore to Generator
breaker rating.
1.The installer should have knowledge and experience in installing electrical equipment, knowl-
edge of the applicable installation codes, and awareness of the hazards involved in performing elec-
trical work and how to reduce those hazards. A qualified technician or electrician has this
knowledge and experience.
2.External AC circuits are AC loads that are not directly controlled through the Freedom Se-
quence’s available six (or four) AC relays.
3.Load shedding is defined as cutting power to loads that are drawing current from the system in
order to avoid an overload condition.
4.Priority swapping is defined as the automatic prioritization of loads when one load has been as-
signed a different priority number.
