General recommendations
The Xtender falls within protection class I (has a PE connection terminal). It is vital that a protective
earth is connected to the AC-In and/or AC-Out PE terminals. An additional protective earth is
located at the bottom of the unit (See sect 3.6.4 – p. 11/13, tag (17)).
In all cases, the PE conductor for the equipment must at least be connected to the PE for
all equipment in protection class I upstream and downstream of the Xtender (equipotential
bonding). It is mandatory that the legislation in force for the application concerned be
adhered to.
Tighten of the input (13) and output (14) terminals by means of a no. 3 screwdriver (minimum 1.2 Nm
tightening torque) and those for the remote entry ("REMOTE ON/OFF") (7) and "AUX.CONTAC" (8) by
means of a no. 1 screwdriver (0.55 Nm tightening torque).
The cable cross-sections of these terminals must conform to local regulations.
All connection cables as well as the battery cables must be mounted using cable restraints in order
to avoid any traction on the connection.
Battery cables must also be as short as possible and the cross-section must conform with the
applicable regulations and standards. Sufficiently tighten the clamps on the "battery" inputs (fig. 4a
(11) and (12) (10 Nm tightening torque).
Before connecting or disconnecting the entry or exit cables AC-In (13) and AC-Out (14), the
installer must make sure that there is no voltage present in the cables OR on the terminals.
Before connecting the battery, the installer must make sure that the AC-In source and the
AC-Out loads are well disconnected.
