IVT US-16 Mode D'emploi page 7

Operation
• The switching station US-16 may only be connected to 230 V AC/50 Hz.
• Operate only inverters with safe electrical separation (galvanic separation) between input circuit
(battery voltage) and output circuit (230 V).
• Before installation ensure that the inverter output as well as 230 V AC mains supply are voltage free
and equipped with a safety lock system to prevent unintentional start of the device.
• Ensure that the connection cables are connected properly and have good contact, as loose contacts
may cause smoldering fire.
• Do not connect the neutral conductor on the consumer side to earth or protective earth conductor;
as the consumer sockets in particular have no protective multiple earthing (i.e. connection of
PE­grounding wire with the neutral connector).
• The cross sections of the used cables must be selected and secured in compliance with applicable law.
• It is not permissible to use the device for three-phase current.
INSTALLATION
The installation should only be carried out by persons having relevant professional skills. If there is any
doubt, always contact an authorized expert. Use the supplied clamps to connect the protective earth

the consumer is fed over the AC2 input.
Connection version 1:
The 230 V AC mains is connected to the AC2 input (higher priority).
I.e. the battery is spared and the inverter is simultaneously protected against external voltage.
Only if there is no current on AC2, AC1 input switches to power supply by means of the inverter.
