DE51131 Installation Base unit Connection PCRED301005EN - 06/2008 Connection of the base unit The Sepam connections are made to the removable connectors located on the rear panel. All the connectors are screw-lockable. CAUTION DANGER LOSS OF PROTECTION OR RISK OF NUISANCE TRIPPING If the Sepam is no longer supplied with power or is in fail-safe position, the protection functions are no longer active and all the Sepam output relays are dropped out. Check that this operating mode and the watchdog relay wiring are compatible with your installation. Failure to follow this instruction can result in equipment damage and unwanted shutdown of the electrical installation HAZARD OF ELECTRIC SHOCK, ELECTRIC ARC OR BURNS b Only qualified personnel should install this equipment. Such work should be performed only after reading this entire set of instructions. b NEVER work alone. b Turn off all power supplying this equipment before working on or inside it. Consider all sources of power, including the possibility of backfeeding. b Always use a properly rated voltage sensing device to confirm that all power is off. b Start by connecting the device to the protective earth and to the functional earth. b Screw tight all terminals, even those not in use. Failure to follow these instructions will result in death or serious injury. Wiring of the CCA620 connector: b Without fitting: v 1 wire with maximum cross-section of 0.2 to 2.5 mm2 (AWG 24-12) or 2 wires with maximum cross-section of 0.2 to 1 mm2 (AWG 24-18) v Stripped length: 8 to 10 mm (0.31 to 0.39 in) b With fitting: v Recommended wiring with Telemecanique fitting: - DZ5CE015D for 1 wire 1.5 mm2 (AWG 16) - DZ5CE025D for 1 wire 2.5 mm2 (AWG 12) - AZ5DE010D for 2 wires 1 mm2 (AWG 18) v Tube length: 8.2 mm (0.32 in) v Stripped length: 8 mm (0.31 in). Wiring of the CCA622 connector: b Ring lug connectors 6.35 mm (1/4 in) b Wire with maximum cross-section of 0.2 to 2.5 mm2 (AWG 24-12) b Stripped length: 6 mm (0.236 in) b Use an appropriate tool to crimp the lugs onto the wires b 2 ring or spade lugs maximum per terminal b Tightening torque: 0.7 to 1 N m (6 to 9 lb-in). Characteristics of the 4 base unit relay outputs O1, O2, O3, O4 b O1 and O2 are 2 control outputs, used by the breaking device control function for: v O1: breaking device tripping v O2: breaking device closing inhibition b O3 is a non assigned control output. b O4 is a non assigned indication output. It can be assigned to the watchdog function. 6/9 6
