Before You Begin
Before you begin installation, please read the following guidelines:
Mag-FLEX probes are intended for installation and operation in the highly combustible environment of a petroleum
fuel storage tank. It is essential that you carefully read and follow the warnings and instructions in this manual to
protect yourself and others from serious injury, explosion, or electrical shock.
For safety reasons, we have taken particular care in the design of this product to limit the power in the wiring to the
fuel tanks and to keep that wiring physically separated from any other wiring. It is your responsibility to maintain the
effectiveness of these safety features by installing this product in accordance with the following instructions and
warnings. Failure to do so could create danger to life and property.
Failure to install this product in accordance with its instructions and warnings will result in voiding of all product
warranties.
EQUIPMENT PROTECTION
TLS monitoring equipment, including the Mag-FLEX Probe, is designed and certified to comply with the Directive
94/9/EC (ATEX) and the IECEx scheme. The installer must consider any local regulations, which may differ or be
more stringent, prior to installing any equipment. The suitability/safety of any installation is ultimately determined by
the local authority having jurisdiction.
The Mag-FLEX Probe is part of the TLS Monitoring System and can be installed in equipment Category 1 and is
suitable for use in a Zone 0 hazardous location. Extreme care must be taken when determining the suitability of the
installation conditions and operation of the TLS Monitoring System. The Mag-FLEX probe is provided with a
standard process connection suitable for the boundary between zone 0 and zone 1 locations. In addition to the
mounting location and method, at least the following items must be considered and will aid in the determination if a
probe is to be installed in the boundary between Zone 0 and Zone 1 or if it will be installed directly in a Zone 0
hazardous location:
WARNING
The Mag-FLEX is installed and operated in the highly combustible environment of a petroleum
storage tank,
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY PRECAUTIONS
COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT, RESULTING IN SERIOUS INJURY OR
