Annex A: Installation
1.
Installation site.
In order to warrant a trouble-free operation of the Gas Monitor
2240 PROcheck
the equipment should be installed in a vibration-free
installation site.
The installation location is to be selected in such a manner that the in-
strument may be operated and read with ease. It is equally important that
the activated carbon filter installed behind the instrument front panel is
easily accessible for scheduled filter replacement.
For cooling purposes the instrument must be set up in such a manner that
free circulation of the ambient air is unobstructed. On the other side it
must also be protected from exposure to very dusty environment or to
splash-water.
In practice a clearance of at least 5 cm (2 inches) away from any
surrounding wall must be kept to permit proper cooling.
The instrument has been designed for operation in an ambient tempera-
ture range from +10°C (50°F) up to +40°C (104°F) maximum. Conden-
sation of air humidity is to be avoided. An integrated protection mecha-
nism will switch off the measuring operation if the maximum permissible
internal temperature is exceeding a limit of + 55°C (131°F). In this case
the instrument will issue a malfunction message.

Electric connection
Nominal Supply voltage:
90 - 264 Volt AC
Frequency:
47 - 63 Hz
Power Consumption:
max. 65 W
Connection of the instrument to the mains should be secured with a
safety fuse (e.g. automatic fuse 8 A) and it should be separated from the
mains connection of the plant resp. machine. If both connections are cir-
cuited together there is a danger of infiltration by electromagnetic bursts
via such direct connection with the plant. Securing such problematic
interconnection against electromagnetic disturbance would be an
alternative.
