CSA Class 1 Division 2 Option
CSA Class 1 Division 2 is Available Only on Specifically Marked Units
If marked this for Class 1 Division 2 – then this product is available for use in Class 1, Division 2,
in the indicated Groups on the product.
In such a case the following must be met:
The transceiver is not acceptable as a stand-alone unit for use in hazardous locations. The
transceiver must be mounted within a separate enclosure, which is suitable for the intended
application. Mounting the units within an approved enclosure that is certified for hazardous
locations, or is installed within guidelines in accordance with CSA rules and local electrical and
fire code, will ensure a safe and compliant installation.
Do not connect or disconnect equipment unless power has been switched off or the area is
known to be non-hazardous.
Installation, operation and maintenance of the transceiver should be in accordance with the
transceiver's installation manual, and the National Electrical Code.
Tampering or replacement with non-factory components may adversely affect the safe use of
the transceiver in hazardous locations, and may void the approval.
The wall adapters supplied with your transceivers are NOT Class 1 Division 2 approved, and
therefore, power must be supplied to the units using the screw-type or locking type connectors
supplied from Microhard Systems Inc. and a Class 1 Division 2 power source within your panel.
If you are unsure as to the specific wiring and installation guidelines for Class 1 Division 2
codes, contact CSA International.
