• Only open the controller cover if the following conditions are met:
- An explosive atmosphere is not present
- All device technical data is observed (see nameplate)
- An electrostatic charge (e.g., caused by friction, cleaning or maintenance)
is avoided on the attached stainless steel nameplate, if present, and on
painted metallic housings that are not integrated into the local potential
equalization (ground) system
• In potentially explosive atmospheres:
- Do not disconnect any electrical connections while the equipment is ener-
gized.
- Do not open the connection compartment cover when energized or the
area is known to be hazardous.
• Install the controller circuit wiring according to the Canadian Electrical Code

The provided warranty is only in effect if the analyzer system is installed and used
as described in the Operating Instructions. The analyzer system is equipped with
security mechanisms to protect it against any inadvertent changes to the system
settings. IT security measures are in line with operators' security standards and
designed to provide additional protection for the and data transfer must be imple-
mented by the operators themselves.

Protecting access via hardware write protection

Write access to the device parameters via the local display or Web browser can be
disabled via a write protection switch (DIP switch on the motherboard). When
hardware write protection is enabled, only read access to the parameters is possi-
ble.
Before servicing, shut off all power to the analyzer.
