Putting into Operation
4.3 Electrical connections
Caution:
Observe the country-specific regulations when making connections (e.g. in Germany
DIN VDE 0100 with residual current device (RCD)). Remember the connected loads and
power values (see nameplate and also chapter " Technical data " on page 14 ).
The constant climate chamber is intended for operation on an electrical power system with
a system impedance Z
max
at the point of transfer (service line) of a maximum of 0.292 ohm.
The operator must ensure that the constant climate chamber is operated only on an electrical
power system that meets these requirements. If necessary, you can ask your local energy sup-
ply 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).
4.4 Switching on
To switch on the appliance, press the main
switch on the front of the appliance ( Fig. 11 ).
Caution:
The first time the appliance is oper-
ated, it must not be left unattended
until it has reached the steady state.
