13.5.2.1 Specific Conditions of Safe Use
1. Warning: The equipment contains non-metallic enclosure and
process parts. To prevent the risk of electrostatic sparking, the
non-metallic surface should only be cleaned with a damp cloth.
Painted surface of the equipment may store electrostatic charge
and become a source of ignition in applications with a low relative
humidity <~30% relative humidity where the painted surface is
relatively free of surface contamination such as dirt, dust or oil.
Cleaning of the painted surface should only be done with a damp
cloth.
2. Cables shall be rated > 5 °C above maximum ambient
temperature.
3. To maintain the ingress protection rating of IP65, Teflon tape
(3 wraps) or pipe dope shall be used. Refer to Installation
Instructions.
4. Equipment can be installed in a boundary wall configuration
where the process connection is installed as Category 1G
equipment while the transmitter housing is installed as Category
2G equipment. Refer to installation instructions.
5. Flexible gauges have a minimum bend diameter of 381mm (15
inches).
6. Flamepaths not for repair.
7. The applicable temperature class, process temperature range and
ambient temperature range of the equipment is as follows;
• T3 with Process Temperature Range of -40 °C to 150 °C
• T4 with Process Temperature Range of -40 °C to 135 °C
• T5 with Process Temperature Range of -40 °C to 100 °C
• T6 with Process Temperature Range of -40 °C to 85 °C
• Ambient Temperature Range -40 °C < Ta < 71 °C
8. When mounting on a MLG (magnetic level gauge) make sure the
electronic head and pressure barrier have a minimum spacing of
5 inches. See Installation Manual for detail.
9. When EPL Ga or Da is required, parts of the equipment containing
light metals (Aluminum or Titanium) shall be protected from
impact so that impact or friction sparks cannot occur, taking into
account rare malfunction. Measures to prevent impact or friction
sparks when using the equipment containing light metals include
but are not limited to:
• Mounting the probe vertically
• No mechanical agitation shall be used
• Use of stilling wells to mitigate effect of agitation.
• Limit rate of change of level to values such that friction sparks
cannot occur
