The mass of a typical BUSBAR box is 270 kg The unsuppted mass of the cables should be added. It is recommended that the enclosure also be secured to a substantial vertical surface. It is recommended that the bus bar closest to the do be selected as the neutral (where applicable) followed by the phases red (Brown), yellow (grey) and blue (black) wking towards the rear of the box. If the wiring system does not include a neutral then the bus bar nearest the do may be used f earthing/grounding not used at all. Two fmats are available :- 1 - BUSBAR box f single ce cables. This design allows f either a through connection (in at the bottom, out at the top) side connection (in and out at bottom only top only). single 2 - BUSBAR box f multi-ce cables. This design permits only single side connection and incpates the use of a trifurcating box to allow the splitting of a multi-ce cable into single ces befe they enter the bus bar chamber. 1 BUSBAR box f single ce cables A.B.

This will allow essential access to the bus bar. d) Check that the bus bar clamp securing nut spring washers are fully compressed. It should not be necessary to adjust these but if necessary the tightening tque is 10Nm minimum, 15Nm maximum. e) Attach the cable glands to the gland plate in accdance with the manufacturer s instructions. f) Prepare the first cable in accdance with the cable gland manufacturer s instructions. (This should be one of the cable ces f the blue phase f attachment to the rearmost bus bar). Leave sufficient length of cable ce and ce insulation to comftably reach the crimp type terminal supplied. Remember to include the length of the crimping barrel. g) Insert the cable through the cable gland and secure the armouring (if applicable) in accdance with the gland manufacturers instructions. If a stuffing gland is used secure the cable by tightening the sealing nut. h) Carefully mark the cable to length so that the conduct will reach the stop on the inside of the crimping lug barrel. The cable ce should have no intentional bends. The cable gland used should be directly below ( above f top entry) the crimping lug barrel. i) Remove the cable from the gland and trim the conduct to length. j) Cut back the conduct insulation. The length of the exposed conduct should be no me than 5mm longer than the internal length of the crimping lug barrel. k) Insert the cable through the appropriate cable gland again and into the barrel of the crimping lug to check f crect length. If armoured cable is used check that the armouring will clamp in the cable gland as intended by the gland manufacturer. l) Once the crect length has been established make careful note of all the cable stripping lengths f repeat use. m) Remove the applicable crimping lug from the bus bar assembly. n) Partially Insert the cable ce through the appropriate cable gland again and push the crimping lug onto the conduct. o) Rotate the crimping lug so that the face which contacts with the bus bar is both facing and parallel to the rear of the box. p) Crimp the barrel onto the conduct using the crect size crimping die set. This may be of the indenting hexagonal type. q) Lift the cable and lug to just below the bus bar assembly and insert the M20 x 55 mm high tensile steel bolt through the hole in the palm of the lug. r) Lift further until the bolt will locate in the fixing hole in the bus bar assembly. s) Push the bolt through the bus bar assembly and secure the lug in place with the nut. Tighten moderately and check again that the cable gland will adequately clamp the cable armour as intended by the gland manufacturer. DO NOT CLAMP THE ARMOUR AT THIS TIME. t) Using the measurement notes taken of the now installed cable prepare each of the other cables. u) Repeat from j), (above), checking f length against the prepared cable and lug assembly, then l), m), n) & o). v) Once all the cables have been installed apply a tque of 185Nm to each connection bolt. w) Replace both of the undrilled (blank) gland plates complete with gaskets and secure the M8 gland plate fixings to 6Nm approx. x) Replace the enclosure lid. The ABTECH BUSBAR BOX is now ready f use. F operation and maintenance see page 4 2 BUSBAR box f multi-ce cables The BUSBAR box f multi-ce cables is generally supplied with a trifurcating box. a) Mount the BUSBAR box assembly complete with trifurcating box on the suppt frame and secure. b) Remove the do from both boxes. c) Fit the cable gland f one of the incoming multi-ce cables to the base gland plate of the trifurcating box. d) Fit the cable glands f each ce of the multi-ce cable to the underside of the gland plate separating the BUSBAR box and the trifurcating box. e) Remove the top plate of the BUSBAR box.

The lid must be secured using all the lid screws provided in der to maintain the IP rating. 2. No attempt must be made to remove the enclosure lid whilst electrical power is connected to the contents of the enclosure. 3. The earthing/grounding facility must be connected to the earth bonding circuit at all times when electrical power is connected to the enclosure. Maintenance Routine maintenance is likely to be a requirement of local health and safety legislation. The laws of the applicable country must be considered and maintenance checks carried out accdingly. Additional checks that are advisable to ensure the efficiency of the ABTECH BUSBAR unit are :- Activity Frequency 1 Check that the lid seal is not damaged and is in place Each time the enclosure is opened 2 Check that all lid fixing screws are in place and secured Each time the enclosure is opened 3 Check that all gland plate fixing screws are in place and secured Each time the enclosure is opened 4 Check that the mounting bolts are tight and free of crosion Annually 5 Check the security of all cable glands Annually 6 Check the enclosure f damage Annually 7 Check that all screw clamp terminals are secure As manufacturers recommendation Earthing balls There is an optional facility f safety during routine maintenance. Special bus bar spacers are available fitted with earthing balls f the connection of ptable earthing equipment. Where these are fitted an acrylic front shield is also fitted f the insertion of a check dead stick. Once the circuit has been confirmed dead the acrylic shield, held in place with 2 off M10 nylon nuts, must be removed and ptable earthing equipment connected to each earthing ball in accdance with the earthing kit manufacturer s instructions. On completion of any routine maintenance, ensure all ptable earthing equipment has been removed pri to refitting the acrylic shield and securing it in place. Chemical Attack The ABTECH BUSBAR units are manufactured from the following materials :- 316 stainless steel Neoprene, EPDM silicone rubber Neoprene bonded ck Glass reinfced polyester Copper High tensile steel. Consideration should be given to the environment in which the BUSBAR unit is to be used to determine the suitability of these materials to withstand any crosive agents that may be present. Static Hazard ABTECH BUSBAR units do not present a hazard from static electricity. Vibration The ABTECH Bus Bar boxes are designed f use in areas subject to nmal industrial levels of vibration. They are not designed f use in areas subject to intentional extreme conditions of vibration. Protection From Feseeable Faults Circuits connected in the enclosure must be externally protected using suitable circuit interruption devices to prevent overloading. Provided the enclosure is crectly installed, there are no feseeable faults. A.B. Controls and Technology Ltd, Sanderson Street, Lower Don Valley, Sheffield S9 2UA England 4 / 4
