PBS-200-A Single entry power junction box Installation Instructions Overview Technical data This manual introduces the installation and operation of the BARTEC PBS-200-A Single entry power junction box. The trace heating system uses a self-regulating trace heater. It features a temperature-dependant resistive element between two parallel copper conductors, that regulates and limits the heat output of the trace heater according to the ambient temperature. If the ambient temperature rises, the power output of the trace heater is reduced. This selfregulating property prevents overheating which would cause damage to the trace heater. Even crossing or overlapping with other trace heaters (or other portions of the same trace heater) are possible. The heating system is set up as a fixed equipment heating system for pipes in ordinary and hazardous areas. Thanks to the parallel design the trace heater can be cut and installed to any required length. The manual applies for the following trace heaters: BARTEC PSB BARTEC HSB The following terms describe the parts of the trace heater within these instructions: Certifications / Approvals bus wire PBS-200-A Single entry power junction box for BARTEC PSB / HSB trace heaters heating element insulation jacket grounding braid outer jacket Ambient temperatures -67 to 131 F / -55 to 55 C Operation temperatures Voltage Heat output Resistance Explosion protection Heater dimensions PSB HSB PSB HSB Minimum bending radius Maximum power conductor size Terminals Safety -40 to 150 F /-40 to 65 C -76 F to -250 F / -60 C to -120 C 110 to 254 VAC 3 to 20 W/ft Grounding braid: < 18.2 Ω/km Class I, Div 2 Group A, B, C, D Class II, Div 2 Group E, F, G Class III (for information on T-ratings see the design guide of the trace heater) 0.46 x 0.22 (11.6 x 5.6 mm) 0.40 x 0.19 (10.2 x 4.8 mm) 1 (25 mm) Do not bend on the narrow axis. 10 AWG (6 mm²) Spring clamp EX e 2x3 lines, 1x3 PE For safe installation and operation of the PBS-200-A Single entry power junction box the technical requirements and instructions given in this manual must be followed.

PBS-200-A Single entry power junction box Installation Instructions Required tools The following tools are required for installation of the trace heating system: Wire cutters Flat screwdriver Cross-head screwdriver Electricians screwdriver Tape measure Utility knife Needle-nose pliers (2x) Tongue and groove pliers Crimping pliers Unrolling the trace heater WARNING Risk of short cuts and/or material damage. Keep the trace heater ends dry before and during installation. Observe the trace heater s installation instructions. Unroll the required trace heater in a straight line and cut to the correct length. Cut off the trace heater ensuring a straight cut. Do not bend or pinch the trace heater, or pull it over sharp edges. 3 2 x Installation on pipes This step is necessary for plastic pipes only since plastic pipes conduct heat less efficiently than metal pipes do. For metal pipes continue with step 5. 2 x Place aluminium tape where the trace heater will be attached for better heat distribution. 4 Cautions and warnings WARNING Risk of fire or electrical shock. De-energize all power circuits before installation or servicing. Always use ground fault equipment within the heat tracing system. Double-check that all power circuits are de-energized before you begin your work. Make sure that you do not exceed the maximum heating circuit length for the trace heater type you use. 1 2 CAUTION Risk of injury and/or material damage. Never tread on or drive over the trace heater. Do not use it as a loop for stepping on. Preferably install the trace heater in a straight line around the pipe. This saves time, helps to avoid installation mistakes and prevents damage to the trace heater during the thermal insulation work. Furthermore the trace heater can be easily localised later on. The trace heater should be installed spirally only if this is expressly specified in the project planning. NOTICE When installing allow for an additional length of trace heater for assembling splice connections, tee branches, end seals etc. (approx. 1.6 ft (0.5 m) for each). 5 Page 6 / 21
Preferably install the trace heater in the lower half of the pipe, but not on the lowest point. This prevents mechanical damage and allows for better heat distribution. If you use multiple trace heaters, position them with an offset of 90. Preparation of the trace heater For splice connections the following instructions apply for both trace heaters. Pass the trace heater through the base unit of the mounting stand. Do not fix the mounting stand on the pipe yet. 6 Fastening At first, select the correct fastening material: Always use polyester adhesive tape or glass cloth tape that suits the expected temperatures. Preferably use BARTEC adhesive tapes. Never use PVC insulating tape or self-adhesive tapes containing PVC or VC. Do not use metal fixtures. 9 7 Slide the trace heater grommet onto the trace heater and into the seal seat. Slide the blind plug into the free seal seat. Make sure that the trace heater stands out approximately 10 (25 cm). This makes cable preparation easier. Fasten the trace heater with the adhesive tape or zip ties at intervals of at least 12" (300 mm) on plastic pipes or 36" (900 mm) on steel pipes. NOTICE In order to ensure good heat transmission the trace heater must have a flat, flush fit over the whole length. If necessary, reduce the distances between the fixing points. 10 8 Page 7 / 21
