2.10 Environmental conditions
► The test chamber may only be used in enclosed rooms and under the following environ-
mental conditions:
Ambient temperature: 16 ºC to 28 ºC
Air humidity: max. 70 % not condensing degree of pollution: 2
Altitude of installation max. 2000 m above sea level
► The test chamber may not be used in areas where there is a risk of explosions. The ambi-
ent air must not contain any explosive dusts, gases, vapours or gas-air mixtures. The test
chamber is not explosion-proof.
► Heavy dust production or aggressive vapours in the vicinity of the appliance could lead to
sedimentation in the chamber interior and as a consequence, could result in short circuits
or damage to electrical parts. For this reason, sufficient measures should be taken to pre-
vent large clouds of dust or aggressive vapours from developing.
2.11 Connections
Observe the country-specific regulations when making connections (e.g. in Germany DIN VDE
0100 with RCD circuit breaker).
This appliance is intended for operation on an electrical power system with a system imped-
ance 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.
2.12 Standard accessories
► Steel grids
► Silicone plugs to close up the cable feed-through in the right-hand side wall (see Fig. 18
