The device can be installed and operated safely in hazardous locations covered by the above ratings
provided the following safety instructions and warnings are followed.
External Electrical Connections
WARNING: The external connector is not intended for use in hazardous locations.
Electrical rating: Um=250Vrms for non-intrinsically safe sources connected in non-hazardous locations.
While it may be possible to connect certain equipment in a safe manner, a field evaluation must be
carried out by the relevant authority and installations certified on a case-by-case basis.
Static Electricity Warning
WARNING: the housing of this product is made of non-conductive material that may build an ignition-
capable electrostatic charge under certain conditions. Do not touch, wipe, or clean the unit in hazardous
environments. Installation and maintenance should only be performed when the environment has been
confirmed to be safe.
Metal Protection Bracket Installation
WARNING: The measured capacitance of the worst case unearthed protection bracket was determined to
be 124.6 pF as measured per clause 26.14 of IEC 60079-0: 2011. It is the installer's responsibility to
determine safe use conditions when installing in a hazardous location where proper grounding of the
bracket is not guaranteed or the bracket is purposefully insulated.
In most cases, the bracket should be grounded to the asset by maintaining metal-to-metal contact
between the bracket and the mounting surface. A separate grounding wire connected to the provided
location on the bracket may also be used.
The bracket may be painted or powder-coated provided the maximum coating thickness is less than
0.2mm.
