Installation and Operating Instructions 723.932 Xtender V0.511 Seite 8
3.6 Connections 3.6.1 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 between the two fastening screws at the bottom of the unit (fig. 2b-(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 imperative 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 and those for
the “REMOTE ON/OFF” (7) and “AUX.CONTAC” (8) by means of a no. 1 screwdriver.
The cable 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 section must conform with the
applicable regulations and standards. Sufficiently tighten the clamps on the “battery” inputs (fig.
4a (11) and (12)).
3.6.2 DEVICE CONNECTION COMPARTMENT
The unit’s connection compartment must remain permanently closed when in operation.
It is imperative to close the protection cap on the connection terminals after each
intervention in the device.
After opening, check that all sources of AC and DC voltage (batteries) have been
disconnected or put out of service.
