4.0 OPERATION
The junction boxes come complete with a range of standard terminals with options such as earth continuity, internal
conductive coating and external paint finishes depending on product ordered.
The maximum voltage and current ratings are stated on the unit label.
5.0 MAINTENANCE
During the working life of the unit, it should require little or no maintenance. GRP will resist attack by most acids,
alkalis and chemicals and is as resistant to concentrated acids and alkalis as most metal products.
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 MEDC. 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 Engineers at MEDC.
To aid assembly/removal of the cover, a thin smear of grease is required on the top face of the enclosure. If this grease
needs to be re-applied, particularly if the O-ring is to be replaced, a PFPE (Perfluoropolyether) based grease such as
Krytox GPL203 by DuPont or Perfluorolube 22/6 by Performance Fluids Ltd should be used, to prevent damage to the
O-ring.
Where units are fitted with terminal rail assemblies, additional terminals must not be fitted as this will affect certification.
Replacement terminals and terminal rail assemblies must be supplied by MEDC on a like for like basis only.
