Quick Start Guide
Special Conditions for Safe Use (X):
1. Appropriate cable, glands, and plugs need to be suitable
for a temperature of 5 °C greater than maximum specified
temperature for location where installed.
2. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that could cause electrostatic
build-up on painted surfaces and only clean the painted
surfaces with a damp cloth. If paint is ordered through
a special option code, contact the manufacturer for more
information.
3. This device contains a thin wall diaphragm less than 1
mm thick that forms a boundary between Category 1G
(process connection) and Category 2G (all other parts
of the equipment). The model code and datasheet are
to be consulted for details of the diaphragm material.
During installation, maintenance, and use, the environmental
conditions to which the diaphragm will be subjected shall
be taken into account. The manufacturer's instructions for
installation and maintenance shall be followed in detail to
assure safety during its expected lifetime.
4. Flameproof joints are not intended for repair.
Conduit/cable entries
Unless otherwise marked, the conduit/cable entries in the housing
enclosure use a ½-14 NPT form. Only use plugs, adapters, glands, or
conduit with a compatible thread form when closing these entries.
Entries marked M20 are M20 x 1.5 thread form. On devices with
multiple conduit entries, all entries will have the same thread form.
When installing in a hazardous location, use only appropriately listed
or Ex certified plugs, glands, or adapters in cable/conduit entries.
