Installation
Main power supply
It is the installer's responsibility to
ensure that units are protected by an
electrical disconnect device such as a
fuse or circuit breaker. Standard
units are supplied without any
protection. The recommended fuse
size is given in the Technical data
table.
All electrical connections must be
made on the terminal blocks of the
main electrical control box.
WARNING ! Disconnect the power
supply before making electrical
connections. Failure to do so may
cause serious injuries as well as
irreversible damage to certain
electrical components.
WARNING! Use copper
conductors only. Unit terminals
are not designed to accept other
types of wiring. Aluminium or
other materials could lead to
galvanic corrosion or overheating
at the contact point thus
damaging the unit. The
customer's electrical connections
must comply with current
standards.
FWD units manufactured by Trane
comply with CEI regulations.
All power supply wiring must be
sized and selected in accordance
with local code and regulation.
Fast-acting circuit breaker, which is
sensitive to very low levels of current
leakage to ground (max 30mA) must
be installed as a general line
protection.
Only copper conductors (Min.
1.5mm
2
- Max 4.0mm
2
) must be used
as unit terminals are not designed to
accept other types of wiring.
