Explosion hazard
Do not disconnect equipment when a flammable or combustible
atmosphere is present.
Do not remove or replace lamps or fuses unless power has been
disconnected or when a flammable or combustible atmosphere is
present.
Failure to observe these safety instructions may result in death, severe
personal injuries and or substantial damage to property and
environment.
ULTRAMAT 23 Type 7MB2335, 7MB2337 and 7MB2338 must be
installed in a suitable enclosure in accordance with EN 60079-15,
taking into account all environmental conditions under which the
equipment will be used.
When the temperature under rated conditions exceeds 70 °C at the
cable or conduit entry point, or 80 °C at the branching point of the
conductors, the temperature specification of the selected cable must be
in compliance with the actual measured temperature values.
Provisions must be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40%.
2.2 Assembly instructions
S A location should be selected which is as free as possible from
vibration. The permissible ambient temperature must be observed
during operation.
S The ULTRAMAT 23 must be placed on supporting rails if it is to be
fitted in a cabinet or benchtop housing. Assembly only at the front is
insufficient because the weight of the analyzer would place too great
a load on the chassis.
S The heat sink on the rear panel must be unrestricted to permit
appropriate air circulation.
