4.0 Maintenance
During the working life of the unit, it should require little
or no maintenance. However, if abnormal or unusual
environmental conditions occur due to plant damage or
accident etc., then visual inspection is recommended.
If the unit requires cleaning, then only clean exterior with
a damp cloth to avoid electro-static charge build up.
If a unit fault should occur, then the unit can be repaired
by Eaton. All parts of the unit are replaceable.
If you acquired a significant quantity of units, then it is
recommended that spares are also made available.
Please discuss your requirements with the Technical Sales

Introduction
(-55°C to +70°C)
(-55°C to +55°C)
The SM87HXB Beacon has been designed for use
in potentially explosive atmospheres and harsh
(-55°C to +40°C)
environmental conditions. The marine grade alloy or
(-55°C to +55°C)
stainless steel enclosures are suitable for use offshore
(-55°C to +40°C)
or onshore, where light weight combined with corrosion
resistance and strength is required.
