1. Safety
1.1 Applicable Use
These particulate monitor systems are not designed for use as a functional safety device and do not
carry a SIL rating. The device must not be used as part of a safety system or as an input signal to a
safety system. These monitors are designed for general process and environmental monitoring.
1.2 General
This apparatus is available with various agency approvals as noted in the approvals section. All
versions of this device have been designed to comply with EN 61010, safety requirements for
electrical equipment for measurement, control and laboratory use, and are supplied in a safe condition.
Before beginning an installation the following safety precautions and all precautions throughout this
manual and in the installation drawings must be followed.
AREA CLASSIFICATION
• Before installing any device confirm area classification requirements. Do
not install any device that is not tagged as suitable for the required area
classification.
• WARNING – Substitution of components may impair suitability for
Division 2 hazardous locations.
PROCESS AND AMBIENT CONDITIONS
• Before installing any device, confirm ambient temperature, process
temperature and process pressure requirements. Do not install any device
that is not tagged as suitable for the required temperatures and pressures.
Confirm compatibility of the wetted and non-wetted materials.
INSTALLATION PERSONNEL AND SERVICE
• Only appropriately licensed and trained professionals should perform the
mechanical and electrical installation.
• This device does not contain field serviceable components other than the
line fuse. Only factory personnel can perform service on this equipment.
• For operator safety and to prevent ignition of flammable or combustible
atmospheres always disconnect power before servicing.
GROUNDING AND FUSING
• Before applying power to the instrument, you must connect the sensor
housing and remote electronics housing (two piece configuration) to a
proper earth ground. The sensor housing is connected to earth ground using
the external ground screw. The remote electronics housing is connected to
earth ground through the dedicated ground screw inside the housing.
Grounding to the neutral conductor of a single-phase circuit is not sufficient
protection.
• Only fuses with the required current, voltage and specified type should be
used. Do not use repaired fuses or short-circuited fuse holders.
