16 10.2 Connections Connection to Supply Input connections should be made with two-terminal crimp type lugs. Sections 8.1. a) Connect to a reliably grounded 12VDC to 48VDC SELV source. b) The branch circuit over current protection shall be sized appropriate to the input current and shall not exceed 800A. c) Use minimum 350Kmcm copper conductors for max. rated input current. d) A readily accessible disconnect device that is suitably approved and rated is recommended to be incorporated in the field wiring. e) To be installed in a Restricted Access Location. NOTE: When configured for single feed operation and when the maximum total load current is less than 300A it is only necessary to connect the input feed to one side. CAUTION: When configured for single feed operation where the maximum total load current exceeds 300A it is essential that the input supply is connected to both the A and B inputs Connecting to the Loads Output connections are made to individual output bus bars and the common return. See Section 8.2 for outputs fitted with circuit breakers or TPS fuses or section 8.3 for outputs fitted with GMT fuse modules Connecting the the Alarm Relays The Form C relay contact output connections are made to the terminal block on the right side of the panel. See Section Connecting the Chassis Ground The chassis ground connection is made to the 1/4-20 studs on the left side of the unit. See Section 8.5. This safety ground connection should be made before operating the panel Checking Connections Carefully check the polarity of input connections to the panel and output connections to the loads before operating the panel. Reverse connections will not harm the panel which is POLARITY NEUTRAL but may cause serious harm to the loads. Check to make sure that the chassis safety ground connection is made. Make sure that all connections are clean and secure to minimize contact resistance. Page 16

17 11.0 INSTALLING CIRCUIT BREAKERS The BDP600 employs pluggable circuit breakers and fuse modules that can be easily installed, removed or replaced without the need for any tools. This operation is carried out without the need to dismount the unit from it s installation. Installation, removal or replacement of a circuit breaker and connection or disconnection of a load circuit should be carried out only by only by qualified technical persons who are trained in the use of power systems and are well aware of the hazards involved. Although it may be necessary on some occasions to carry out this operation while power remains applied to the panel, it is always preferable to switch off the power if possible before proceeding Opening the cover To open the cover undo the two knurled retaining screws at the left and right side of the unit and rotate forward Removing a breaker, fuse module or blank panel To remove a breaker or fuse module gently pull the body of the breaker or fuse module until it comes free. To remove a blank panel gently lever it out from the front cover at the top or bottom. NOTE: When removing a GMT or TPS fuse module it is necessary first of all remove all fuses. NOTE: When removing a GMT fuse module it is necessary first of all to disconnect the output cables after making a note of the existing connections Removing a GMT fuse To remove a GMT fuse hold it at the top and bottom of its body and pull gently until it comes free Installing a breaker, fuse module or blank panel To insert a breaker or fuse module carefully push the breaker or fuse module firmly into the socket and make sure that it is fully seated. To fit a blank panel position it in the require location and gently push at the top and bottom until it it fully home. NOTE: When installing a breaker ensure that it is in the OFF position. NOTE: When installing a GMT fuse module follow the instructions in section 8.3 to make connections to the loads. Page 17

18 11.5 Installing a GMT Fuse To install a GMT fuse position it carefully so that the blades are aligned with the socket and then push the center of the fuse body until it is fully seated in the socket. Repeat the above procedure from 11.2 to 11.5 for all positions and then close the cover Connecting or disconnecting load circuits In cases where a breaker or TPS fuse module has been installed follow the instructions in sections 8.2 to connect the new output wiring. In cases where a GMT fuse moduile has been installed follow the instructions in section 8.3 to connect the new output wiring. In all cases ensure that the breaker is in the OFF position or the fuse has been removed until all connections have been made and thoroughly checked. If any 125A, 150A or 200A breakers have been fitted these will require that the supplied link bar is fitted across the associated output bus bars. NOTE: If power remains applied to the panel during breaker installation the alarm LED will show red and the alarm relay will be activated until the new cables have been connected and the breaker set to the ON position or the fuse(s) inserted. Page 18

19 12.0 SETUP AND TESTING 12.1 It is not necessary to have the distribution panel mounted in a rack for initial testing. This can be done on a bench. It is also not necessary to have loads connected to the panel for this testing With the input power source off, connect the input wires to the A side of the distribution panel. Connect ground to the chassis ground terminal. Set all circuit breakers to on and insert all fuses Turn on the input power source. The display should come in and display the input voltage fo the A side. The LED should not come on. If it does one of the circuit breaker is tripped or one of the fuses has blown Use an ohmmeter to check the Form C relay contact outputs. Measure the resistance between pins NO1/C1, NO2/C2 and NO3/C3. This should read open. Measure the resistance between pins C1/NC1, C2/NC2 and C3/NC3. This should read short On the A side trip circuit breaker no. 1. The LED should turn red and the dispay should show an alarm condition. On J4 measure the resistance between pins NO1/ C1, NO2/C2 and NO3/C3. This should read short. Measure the resistance between pins C1/NC1, C2/NC2 and C3/NC3. This should read open. Reset the circuit breaker On the A side check each succeeding breaker by tripping it, and verify that the LED turns red and the display indicates an alarm. It is not necessary to recheck the Form C relay contacts Repeat the same tests of Sections 12.2 through 12.6 on the B side of the distribution panel, use J3 to check the Form-C relay operation The distribution panel may now be connected to its intended application If the distribution panel did not operate properly in the above tests, go back and double check the connections and the polarity of the input source to make sure it is correct.
