1. Introduction
•
Responsibility for the choice of lining and electrode materials as regards abrasion and
corrosion resistance lies with the purchaser; the effect of any change in process medium
during the operating of the meter should be taken into account. Incorrect selection of lining
and/or electrode materials could lead to a failure of the meter.
•
Stresses and loading caused by earthquakes, traffic, high winds and fire damage are not
taken into account during meter design.
•
Do not install the meter such that it acts as a focus for pipeline stresses. External loading is
not taken into account during meter design.
•
During operation do not exceed the pressure and/or temperature ratings indicated on the data
label or in this Operating Manual.
•
It is recommended that all installations include an appropriate safety valve and adequate
means for draining/venting.
•
Under the "Pressure Equipment Directive" (PED) this product is a pressure accessory and
not approved for use as a safety accessory, as defined by the PED.
•
Removal of the terminal box except by Siemens Flow Instruments A/S or their approved
agents will invalidate the PED conformity of the product.
In accordance with "Pressure Equipment Directive" (97/23/EC).
Battery operation:
•
Pulse output and RS 232/RS 485 add-on modules must be connected to equipment
complying with Low Voltage Directive (LVD) in order to be considered safe. The isolation
within MAG 8000 & MAG 8000 CT pulse output is only a functional isolation.
•
Lithium batteries are primary power sources with high energy content. They are designed to
meet the highest possible safety standard. They may, however, present a potential hazard
if they are abused electrically or mechanically. This is in most circumstances associated with
the generation of excessive heat, where increased internal pressure may cause the cell to
rupture.
Thus the following basic precautions should be observed when handling and using lithium
batteries:
− Do not short-circuit, recharge, overcharge or connect with false polarity.
− Do not expose to temperature beyond the specified temperature range or incinerate the
battery.
− Do not crush, puncture or open cells or disassemble battery packs.
− Do not weld or solder to the body of the battery.
− Do not expose contents to water.
•
Lithium batteries are regulated under United Nations Model Regulations on Transport of
Dangerous goods, UN document ST/SGAC.10-1, 12
class 9 covers lithium batteries packed with or inside the equipment. UN no. 3090 class 9
covers transportation of batteries on their own.
Thus the following basic precautions should be followed when transporting lithium batteries:
− Transport only in special packaging with special labels and transportation documents.
− Exercise caution in handling, transportation and packaging in order to prevent short
circuiting of the batteries.
− The gross mass of the package is limited according to the type of transportation.
In general, a gross mass below 5 kg is acceptable for all forms of transportation.
•
Remove the battery from transmitter before returning the flowmeter to Siemens for service or
warranty claim.
