Putting into Operation
4.5 Connecting
Caution:
Observe the country-specific regulations when making connections (e.g. in Germany
DIN VDE 0100 with an RCD circuit breaker). Also observe the connected loads and
power values (see chapter 2.9 Technical data on page 17 ).
The test chamber is intended for operation on an electrical power system with a system im-
pedance Z
max
at the point of transfer (service line) of a maximum of 0.292 Ohm. The operator
must ensure that the test chamber is operated only on an electrical power system that meets
these requirements. If necessary, you can ask your local energy supply company what the
system impedance is.
Only appliances may be connected to external connections whose interfaces comply with the
requirements for safety extra-low voltage (e.g. computer, printer).
► Switch on appliance by pressing the main switch on the front of the appliance (see Fig. 18
on page 27 ).
Caution:
The first time the appliance is operated, it must not be left unattended until it has
reached the steady state.
