7.0 Maintenance
Little or no maintenance is required during the normal working life of the
product. The Klaxon Intrinsically Safe enclosures are resistant to most acids,
alkalis and chemicals and have been designed to withstand severe weather
conditions. However it is suggested that continuous supervision and periodic
inspections may be required in relation to the requirements of the installation as
per IEC 60079-17.
To avoid the possibility of a potential electrostatic charge build up, it is
recommended that the exterior of the product is periodically wiped down with
a clean damp cloth. At this point a visual inspection is recommended to ensure
that the product is in good working order and no damage has been sustained
during its normal operation.
The enclosure is non-conducting and may generate an ignition-capable level of
electrostatic charge under certain extreme conditions. It is the responsibility of
the user to ensure that the equipment is installed in a location where it will not
be subjected to external conditions that might cause a build-up of electrostatic
charge on the surface of the unit,
8.0 Conditions for Use
The Klaxon Intrinsically Safe Signalling Range uses an enclosure rated at
IP66*. To ensure that this rating is maintained once installed, a suitable cable
gland must be used which matches this level of protection. The base of the unit
contains 3x M20 knockouts for wiring in purposes, and only those required
should be used. Any that are removed must have at least an IP66 rated gland
fitted with cable passing through it or suitable plug.
*= meets the IP33C requirements of EN 54-3:2001+A1:2002+A2:2006.
