Specific condition of use
- Precautions shall be taken to minimize the risk from electrostatic discharge of non-metallic parts and
painted parts of the enclosure. When the equipment used in hazardous locations, avoid any action
which generate electrostatic discharge such as rubbing with a dry cloth.
-
The cable gland accompanying the equipment may not provide sufficient clamping. Additional clamping
of the cable shall be provided to ensure that pulling and twisting are not transmitted to the termination.
Alternatively, an Ex d, Ex e, or Ex n cable gland which provides sufficient clamping shall be used
instead of the accompanying cable gland.
Notes:
1. Installation must be in accordance with the Canadian Electric Code C22.1 and relevant local codes.
2. Measuring Module 2 is not always installed. As for ISC module and SENCOM module, only one
module is permitted to be installed at a time.
3. For Division 2 / Zone 2 installation, Sensor 1 and Sensor 2 may be equipment suitable for Division 2
/ Zone 2, or simple apparatus, or nonincendive field wiring apparatus with the following nonincendive
field wiring parameters.
Ui (or Vmax) ≥ Uo
Ii (or Imax) ≥ Io
Pi ≥ Po
Ci ≤ Co – Ccable
Li ≤ Lo – Lcable
4. FLXA202 Analyzer must be installed in accordance with one of the following:
a) in a SELV or PELV system, or
b) via a safety isolating transformer complying with the requirements of IEC 61558-2-6, or a technically
equivalent standard, or
c) directly connected to apparatus complying with IEC60950 series, IEC61010-1, or a technically
equivalent standard, or
d) fed directly from cells or batteries.
5. WARNING – POTENTIAL ELECTROSTATIC CHARGING HAZARD AVERTISSEMENT – DANGER
POTENTIEL DE CHARGES ÉLECTROSTATIQUES
6. WARNING – SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR DIVISION 2 /
ZONE 2.
AVERTISSEMENT – LA SUBSTITUTION DE COMPOSANTS PEUT RENDRE CE MATÉRIEL
INACCEPTABLE POUR LES EMPLACEMENTS DE DIVISION 2/ZONE 2
