Quick Start Guide
WARNING
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.
Ensure the power to the level switch is off, and the lines to any other external
power source are disconnected or not powered while wiring the level switch.
Ensure the wiring is suitable for the electrical current and the insulation is
suitable for the voltage, temperature, and environment.
WARNING
Process leaks could result in death or serious injury.
Ensure the level switch is handled carefully. If the process seal is damaged,
gas might escape from the vessel (tank) or pipe.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users' equipment. This could be intentional or
unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users' assets. This is true for all
systems used within the facility.
CAUTION
Hot surfaces
The flange and process seal may be hot at high process temperatures. Allow
to cool before servicing.
