Installation and Operation

Connection and Remote End Termination for PSB Type 27-1680-..10/.... heating system

Operating instructions

1. Product description

The PSB type 27-1680-..10/.... Ex heating system with the

PSB (type 07-5801....) self-limiting parallel heating tape, assembled with a connection and remote end termination system (installation kit 05-0091-0130 and/or 05-0091-0136) in cold connection technology, is set up as a stationary resistance heating system for pipelines or containers in hazardous areas. It is used in Zones 1, 2 or Zone 21 according to the certified explosion group II and temperature classes T5/T6.

After assembly the supply wires and the twisted protective braid of the heating tape are always connected to terminals in an enclosure with „increased safety“ protection class (in conformance to the relevant standards EN 60079-0 and EN 60079-7).

3 . Safety Instructions

The relevant installation and operating regulations must be observed for electrical systems in hazardous areas (e.g. Directive 1999/92/

EC, Directive 94/9EC, EN 60079-14, EN 61241-14 and the

DIN VDE 0100 series).

The requirements under EN 60519-1 and EN 60519-2 must be adhered to.

Thermal Safety Class 0 under EN 60519-2 Section 13 is met by the heating tape’s design characteristics.

The Cu braid with a resistance of < 18.2

/Km is suitable as a protective conductor.

To protect against indirect contact, conductive parts from other firms must be included in the (protective conductor) safety measures. For each electric circuit it is necessary to have a residual-current circuitbreaker and a means of isolating all outer wires from the current supply.

The operator of an electrical system in a hazardous environment has to keep the equipment in an orderly condition, operate it correctly, monitor it and do the required maintenance and repairs.

(EN 60079-14, EN 60079-17, EN 60079-19 and EN 61241-14).

5.a) Assembly

The relevant installation and operating regulations must be observed when setting up or operating explosion-protected systems (e.g.

EN60079-14, EN 60079-30-2 and the DIN VDE 0100 series).

The heating tape must be installed on the workpiece in accordance with the project engineering specifications. Only qualified specialists may do any of the work on the machine. Before any work is done on the machine, it must have come to a complete stop, be disconnected and precautions must be taken to ensure that it cannot be switched on again.

Before and during installation: keep the ends and connection components of the heating system dry. The metallic braiding in this heating system must be connected to a suitable earthing terminal.

!! The bending radius may not be less than the minimum of 25 mm and the heating tape may not be bent on its narrow side.

The heating tape is attached to the workpiece by means of temperatureresistant adhesive tape with a max. spacing of 200 mm!! Use only plasticiser-free adhesive tapes (no PVC adhesive tapes)!

To ensure efficient heat transmission, the heating tape must have even contact over the entire length of the surface. If necessary, the distances between fastenings must be reduced. The tape is laid on

the pipelines either parallel to the axis of the pipe or in spiral form

(in accordance with the project engineering instructions).

On plastic pipes, which conduct heat less efficiently than metal pipes do, aluminium foil or aluminium adhesive tape is put under or over the heating tape. This substantially improves the distribution of heat, prevents a local accumulation of heat and at the same time it partly compensates for the lower heat dissipation and associated reduction in the capacity of the heating tape.

Once the heating system with accessories has been mounted, the insulation resistance between the heating conductor and the metallic braid must be verified.

The testing voltage should be at least 500VDC and the insulation resistance at least 20 M Ω /km EN 60079-30-2 Section 8.3.4)

When used in TT and TN systems a residual current device according to IEC 60079-30-1, clause 4.3 point d) shall be installed. When used in IT systems an insulation monitoring device according to IEC

60079-30-1, clause 4.3 point e) shall be used.

5.b) Commissioning

The equipment may only be operated if it is clean and free of any damage.

Electrical systems must be examined by an electrician before commissioning and afterwards at certain intervals of time.

6 . Operation, maintenance and fault clearance

The heating systems must be used only in accordance with their intended purpose and within the operating data specified by BARTEC.

The operator of an electrical system in a hazardous environment must keep it in good condition, operate it properly, monitor it and do maintenance and repairs. (EN 60079-14, 61241-14).

Only an electrician may do the maintenance work and fault clearance.

Before restarting operation, check compliance with the applicable laws and directives. Before maintenance or troubleshooting, make sure that the specified safety regulations are adhered to.

8 . Type label heating system

The type label is to be filled in manually on the basis of the table and points 1-6. The blanks in the heating system’s type number must be filled on the basis of the components used. A water-proof and lightfast marker must be used (e.g.: Staedtler Lumocolor permanent special marker or BARTEC no.: 02-7140-0001).

The serial no.: and the TAG no. can be filled in by the person setting up the heating-circuit.

A practical example of a filled-in type label is given further on.

The type label must be stuck onto the lid of the junction box. The surface must be cleaned first before the glue is applied. Care must be taken that the sticker is put on carefully. It may not jut out over the correct area and it may not have any air bubbles.

Practical example:

The following components were used:

PSB 120 V 26 W; Cold-applied connection technology and BARTEC polyester junction box.

It was filled in according to the grey-shaded line in the table.
