The existing nickel cadmium battery (15 Ah) is removed from the RH cargo compartment and a high-capacity nickel cadmium battery (22 Ah) or a lead-acid battery (28 Ah) is installed in the tail boom. This eliminates or reduces the need for tail boom ballast and increases the usable volume in the RH cargo compartment. The battery is mounted on a removable tray and is accessible through a cutout approximately 420 mm long x 300 mm wide (16.5 in. long x 11.8 in. wide) in the LH side of the tail boom skin between STN’s A 1578 and A 2295. The cutout is locally reinforced by the addition of externally mounted sheet metal doublers. The battery can be accessed through a carbon fiber door attached to the tail boom with two hinges and secured with two latches. Refer to Figures 1 and 2. The nickel cadmium, Saft 2376 battery type comes with a temperature sensor. The lead-acid, Concorde battery, part number RG-390E is a sealed, valve regulated battery. Refer to Figure 5. The Battery Relocation consists of the following main components: Detachable Provisions - Battery Tray Assembly (Refer to Figure 2) - Battery (Refer to Figures 5 and 6) - Access Door (Refer to Figures 14 and 15) Fixed Provisions - Battery Harness (Refer to Figure 2) - Skin Doublers (Refer to Figure 2) - LH and RH Frame (Refer to Figures 3 and 6) - Base (Refer to Figures 8 to 13) - RH and LH Stiffener (Refer to Figures 8 to 13) For AS 350 PRE MOD 07-3273 and 07-3274, the fuse holder assembly is located in the tail boom between STN’s A868 and A1578. Refer to Figure 8. For AS 350 POST MOD 07-3273 and 07-3274, the fuse holder assembly is located on the battery tray. Refer to Figure 9. For AS 350 B2/B3 POST MOD 07-4280, addition of Direct Battery Bus Circuit Breaker Box on the original Battery Support Rack area. Refer to Figure 10. PRE MOD 07-4836, -01 Variant, Relay 35P has been moved forward of the Main Junction Box and the wire harness at the battery has been changed. Refer to Figure 11. POST MOD 07-4836, -02 Variant has replaced Fuse (F1) with a Terminal Support and Fuse (400A). Refer to Figure 12. For AS 355 the fuse holder assembly is located in the tail boom between STN’s A868 and A1578. Refer to Figure 13. For AS 350 Harness routing in the tail boom, PRE MOD 07-3273 and 07-3274, refer to Figure 8. For AS 350 Harness routing in the tail boom, POST MOD 07-3273 and 07-3274, refer to Figure 9. For AS 350 Harness routing in the tail boom, POST MOD 07-4280 (AS 350 B3), refer to Figure 10. For AS 350 Harness routing in the tail boom, PRE MOD 07-4836, -01 Variant, refer to Figure 11. For AS 350 Harness routing in the tail boom, POST MOD 07-4836, -02 Variant, refer to Figure 12. For AS 355 Harness routing refer to Figure 13. For instructions for initial installation, see IP-ECL-6 for AS 355 or H240I0221580 for AS 350. B.
