Basic Installation Procedures
3. Using a Phillips torque screwdriver, attach the bonding
screw to the AC Out Neutral-to-Earth Bond hole.
4. Tighten the bonding screw to 0.85 N-m maximum torque.
AC Earthing
As per IEC/EN 62477-1, for all permanently connected
equipment: The Freedom XC should be connected to an earthed,
metal, permanent wiring system. Also, make sure that an AC
earth wire is connected to the AC earth terminal on the unit. Do
not just connect the line and neutral wires.
All connections to the unit shall comply with all regulations,
directives, local codes and ordinances.
Residual-Current Circuit Breaker (RCBO)
An RCBO (Type B) is a device that de-energizes a circuit
(disconnects both Line and Neutral conductors) when a current
(AC or DC) to earth exceeds a specified value that is less than
that required to blow the circuit breaker. An RCBO (Type B) is
intended to protect people from electric shocks and are usually
required in wet or damp locations.
Installations in marine and recreational vehicles require RCBO
protection of branch circuits connected to the AC output of the
Freedom XC. The RCBO installation shall comply with all
regulations, directives, local codes and ordinances. EU local
requirements may differ and will take precedence.

DC Cabling
This includes all the cables and connectors between the batteries,
the DC disconnect and over-current protection device, and the
Freedom XC. Mobile installations require multi-strand insulated
cables for flexibility and durability in high vibration environments
and require disconnects and over-current devices. Wire size is
usually marked on the larger sized cables. Table 5 specifies the
minimum recommended DC cable size and maximum fuse size
for the Freedom XC. The DC cables must be stranded,
copper, and must be rated 105 °C minimum. The cables
should be terminated with lugs that fit the DC stud terminals
snugly (8mm hole size) and properly torqued according to
manufacturer-specified torque setting.
