Subject to technical changes.
The isolating transformer acts as a galvanic isolation of consumer loads from the grid-type-network.
He is only suitable for dryly rooms. The ambient temperature should not increase over 40°C.
The device has a 1,5m cable with safety plug for input and a front-side socket without protective
conductor for output. In doing so the power of the consumer loads must not exceed the output power
of the equipment according to the label ( 920 VA ).
Attention:
Only one consumer at the same time may be connected to the transformer. It is not permitted to
connect several devices to use the unit as a distributor. In case of a malfunctioning device, the earth
potential would be fed to other connected devices as well. This implicates that the output voltage
would no longer be free from potential.
In case the equipment does not supply any output voltage, the input and output fuse is to be checked.
To avoid unallowable heating of the equipment, the casing must not be covered.
Toroidal transformers have a high starting current. The pre-connected fuse do not allow such a high
inrush current. To avoid blasting the preliminary fuse while powering on the insulating transformer, the
switch on works with an in-rush-current-limiter. This only takes effect if activating the unit with the
built-in power-switch.
For the warranty of security for users tampering with the equipment by consumers are prohibited.
In case any repairing is necessary the equipment is to be send to the manufacturer.
