B3. Conditions of Certification
FM Approval Specific Conditions of Use
1) For Zone 2 installation with the 24V Power Supply, the installer shall provide transient over-
voltage protection external to the equipment such that the voltage at the supply terminal of the
equipment does not exceed 140% of the voltage rating of the equipment.
2) The enclosure contains aluminum and is considered to present a potential risk of ignition by
impact or friction. Care must be taken into account during installation and use to prevent
impact or friction.
3) Painted surface of the enclosure may store electrostatic charge and become a source of
ignition in applications with a low relative humidity less than approximately 30% relative
humidity where the painted surface is relatively free of surface contamination such as dirt,
dust or oil. Cleaning of the painted surface should only be done with a damp cloth.
CSA, IECEx and ATEX Conditions of Certification
1) Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of
this equipment may generate an ignition-capable level of electrostatic charge. Therefore the
equipment shall not be installed in a location where the external conditions are conducive to
the build-up of electrostatic charge on such surfaces. In addition, the equipment shall only
be cleaned with a damp cloth.
2) The enclosure is manufactured from low copper aluminum alloy. In rare cases, ignition
sources due to impact and friction sparks could occur. This shall be considered during
installation, particularly if the equipment is installed in a zone 0 location.
Apparatus Marked with Multiple Types of Protection
The user must determine the type of protection required for installation of the equipment. The
user shall then check the box [ ] adjacent to the type of protection used on the equipment
certification nameplate. Once a type of protection has been checked on the nameplate, the
equipment will not be reinstalled using any of the other certification types.
