Installation recommendations Installation in switchboard E7658A E7656A E765A E7650A Possible positions Power supply devices can be supplied either from the top or from the bottom without reduction in performance, in order to facilitate connection when installed in a switchboard. Mounting the circuit-breaker It is important to distribute the weight of the device uniformily over a rigid mounting surface such as rails or a base plate. This mounting plane should be perfectly flat (tolerance on support flatness: 2 mm). This eliminates any risk of deformation which could interfere with correct operation of the circuit breaker. devices can also be mounted on a vertical plane using the special brackets. Mounting on rails. E765A E7657A E7652A Mounting with vertical brackets. 9
Partitions Sufficient openings must be provided in partitions to ensure good air circulation around the circuit breaker; For high currents, of 00 A and upwards, the metal supports or barriers in the immediate vicinity of a conductor must be made of non-magnetic material A; Metal barriers through which a conductor passes must not form a magnetic loop. E7659A A A : non magnetic material E7660A E766A Busbars The mechanical connection must be exclude the possibility of formation of a magnetic loop around a conductor.

Installation recommendations Power connection Cables connections If cables are used for the power connections, make sure that they do not apply excessive mechanical forces to the circuit breaker terminals. For this, make the connections as follows: c extend the circuit breaker terminals using short bars designed and installed according to the recommendations for bar-type power connections: v for a single cable, use solution B opposite v for multiple cables, use solution C opposite. c in all cases, follow the general rules for connections to busbars: v position the cable lugs before inserting the bolts v the cables should firmly secured to the framework of the switchboard. Busbars connections The busbars should be suitably adjusted to ensure that the connection points are positioned on the terminals before the bolts are inserted B The connections are held by the support which is solidly fixed to the framework of the switchboard, such that the circuit breaker terminals do not have to support its weight C. (This support should be placed close to the terminals).

E7678A 2 5 Clamping Correct clamping of busbars depends amongst other things, on the tightening torques used for the nuts and bolts. Over-tightening may have the same consequences as under-tightening. For connecting busbars (Cu ETP-NFA5-00) to the circuit breaker, the tightening torques to be used are shown in the table below. These values are for use with copper busbars and steel nuts and bolts, class 8.8. The same torques can be used with AGS-T52 quality aluminium bars (French standard NFA 02-0 or American National Standard H-5-).

Derating in switchboard Factors affecting switchboard design The temperature around the circuit breaker and its connections: This is used to define the type of circuit breaker to be used and its connection arrangement. Vents at the top and bottom of the cubicles: Vents considerably reduce the temperature inside the switchboard, but must be designed so as to respect the degree of protection provided by the enclosure. For weatherproof heavy-duty cubicles, a forced ventilation system may be required. The heat dissipated by the devices installed in the switchboard: This is the heat dissipated by the circuit breakers under normal conditions (service current). The size of the enclosure: This determines the volume for cooling calculations. Switchboard installation mode: Free-standing, against a wall, etc. Horizontal partitions: Partitions can obstruct air circulation within the enclosure.
