Quick Start Guide
Note
Transmitters marked with NI CL 1, DIV 2 can be installed in Division 2 locations using
general Division 2 wiring methods or Nonincendive Field Wiring (NIFW). See Drawing
04088-1206.
Special Conditions for Safe Use (X):
1. The device contains a thin wall diaphragm. Installation, maintenance, and use shall take
into account the environmental conditions to which the diaphragm will be subjected.
The manufacturers instruction for maintenance shall be followed in detail to assure
safety during its expected lifetime.
2. In case of repair contact the manufacturer for information on the dimensions of the
flameproof joint.
3. Appropriate cable, glands, and plugs need to be suitable for a temperature of 5 °C
greater than the maximum specified temperature for location where installed.
4. The applicable temperature class, ambient temperature range and process temperature
range of the equipment is as follows:

04088-1206; Type 4X
Special Conditions for Safe Use (X):
1. The maximum permitted ambient temperature of the Model 4088 Pressure Transmitter
is 70 °C. To avoid the effects of process temperature and other thermal effects care shall
be taken to ensure the surrounding ambient and the ambient inside the transmitter
housing does not exceed 70 °C.
2. The enclosure may contain aluminum and is considered to present a potential risk of
ignition by impact or friction. Care must be taken during installation and use to prevent
impact or friction.
3. The Model 4088 Transmitters fitted with transient protection are not capable of
withstanding the 500V test. This must be taken into account during installation.
Note
Transmitters marked with NI CL 1, DIV 2 can be installed in Division 2 locations using
general Division 2 wiring methods or Nonincendive Field Wiring (NIFW). See Drawing
