pressure (124kPa (18psia)) hazardous area cer�fica�on and the analyser should not be vented to
pressures over 110 kPa (16psia) without these fited. They are external to the analyser and simple to
change in the case of contamina�on. When sample compartment hea�ng is fited these sintered
elements are also heated to 70
°C
, giving further robustness to moisture droplets or aerosols carried over
from the sample system.
During normal opera�on, calibra�on and installa�on it is not required to access this side of the

Power/signal compartment (Figure 4):
This explosion
-
proof compartment contains the components which supply power to the rest of the
analyser, and the components to interface the analyser to your control/monitoring system.
These components include the mA outputs, Modbus digital communica�on (RS485 or Ethernet) and 30
Vdc 1A relay signal outputs which provide fault, concentra�on, maintenance required, service in
progress alarms, mA range indica�on, and op�onal auto valida�on control.
The
analyser electrical supply cable, and the communica�ons cables to your control/monitoring system,
must be connected (through the cable entry holes on the base of the analyser) to the terminals in this
