INTRODUCTION Thank you for purchasing this product! For installation, maintenance and assurance of a long life of this product, please follow this manual. APPROVALS Marking to 2014/34/EU: II 2 G Ex eb IIC T4, T5, T6 IECEx PRE 14.0001 Presafe 14ATEX4124 Enclosure solutions with optional technical specifications upon request. These solutions are subject to unit verification certifications or field certifications. SAFETY INSTRUCTION Tranberg High Voltage A-block series 1060 enclosures, are suitable for use in hazardous areas zone 1-2, and also in safe areas. Changes made to the product which do not confirm to the approvals of this equipment, is a safety violation. The manufacturer is under no circumstances responsible for personal injuries, death or any other damage caused by such activities. For replacement and repair of the enclosure only Tranberg AS spare parts may be used. Repair that effects the explosion protection, may only be carried out by Tranberg AS, or a qualified electrician in compliance with the respective national regulation. Notified Body: DNV Nemko Presafe A/S, Norway Fig. 1 MAINTENANCE / REPAIR / MODIFICATION Before opening the enclosure make sure that the power is disconnected. In case of intrinsically safe circuits, working is permitted while voltage applies. Before starting Maintenance, repair or modification, remove safety cover (see figure 1) and measure that there is no high voltage on the terminals. Servicing the enclosure is done by checking the intactness of the enclosure, gasket and glands. If necessary lubricate the lid bolt threads or the quick lock closing with grease type Renolit Unitemp 2 from Fuchs or equal. If repair or overhaul is necessary this may only be done with Tranberg spare parts. Modification of the enclosure or change of design are not permitted, except for installing additional glands and terminals according to the approval of the enclosure.
INSTALLATION No spare parts, tools, measuring equipment or any other item shall be stored inside the high voltage enclosure. The inside of the enclosure, terminals and cables shall be clean and dry. If dust or water is present, the enclosure shall be disconnected, earthed, cleaned and measures shall be taken to prevent further ingress of dust or water. Measures should be taken to prevent condensation inside the enclosure. An equipotential bonding wire should always be connected to the enclosure. This is to ensure any fault current shall be lead safely to earth, and that the enclosure in no way may be dangerous to touch. The bonding wire should be of a suitable cross section so that it may safely lead the foreseen fault-current to the ground. Installation is to be performed by skilled personnel, familiar with high voltage installations and regulations, Ex regulations, the ATEX Directive and/or IECEx norms and standards. This includes but is not limited to: IEC/EN 60079-0, IEC/EN 60079-7, IEC/EN 60079-14, company routines and national and international regulations. Ferrules shall always be used on fine-stranded cables. All clearance and creepage distances shall be according to IEC/EN 60079-7 after installation. Regardless of the regulations taking precedence in any installation, a dielectric strength test is highly recommended after installation, before the equipment is put in service. In most cases, this test will be mandatory. Disposal/Recycling: When the apparatus is disposed of, the respective national regulations shall be observed. Mounting The 1060 enclosure must be fastened by 4 pcs. of M10 bolts, or M8 bolt at holes in back of enclosure Connection In order to maintain the mode of protection, the conductors will have to be connected with special care. The insulation must reach up to the terminal and the conductor must not be damage. All screw and nut of the terminals, also those remaining vacant, must be tighten down. For earth connection to stud or bar, cable shoes will have to be used. Only certified cable entries and blinds may be used. Gland has to be chosen according to cable diameter used. To ensure the required minimum protection category glands has to be tighten properly and unused holed has to be closed with certified blinds according to hole diameter. Close and lock door / lid. In case of bolt tight these firmly with suitable tool by hand force. Over tightening may impair the protection category. Important The panel must be mounted vertically to a wall or structure. Make sure to use all four (and sometimes more) fixing points, as the weight of the panel with components inside may be considerable. It is also very important that the rear of the panel stays level, meaning that the fixing points on the structure must be in the same plane. If one or more of the fixing points are out of line, the panel is likely to be bent when fixed to the structure. If the panel is bent it may result in several problems, such as: Fault on IP degree of ingress protection, due to certificate. Water intrusion (uneven pressure on door gaskets) Doors may not close completely or become difficult to open The load on the fixing bolts may not be fully distributed (excessive load on some points) Permanent deformation of the panel
