Models 06004-11 (Rear View)

Model 06004-11 includes a fail-safe circuit. Schottky diodes are cross-connected at the input to the power distribution circuits. When both power supplies are energized, power is balanced between the two supplies by the diodes. If one of the power supplies loses its power or is shut down, the other supply shares its power with both outputs (A and B) through the Schottky diodes. The positive battery return circuits for A and B are common since both circuits must operate from either the A or B power source. The fail-safe feature reduces the A and B inputs to 15A maximum for each bus (total 30A per panel).

NOTE

For the Fail Safe load sharing to function properly, the capacity of each of the user-supplied external feeder fuses or breakers must be greater than the total load of the panels A and B outputs combined. For example, if the panel’s total Load A = 10A and Load B = 10A, then the feeder fuse for Side A and Side B must each be at least 20A.

WARNING

WARNING! Failure to properly ground this equipment can create hazardous conditions to installation personnel and to the equipment.

WARNUNG! Bei unsachgemäßer Erdung besteht Gefahr für das Installationspersonal und das Gerät! ¡AVISO! La conexión incorrecta a tierra puede ser peligrosa tanto para los instaladores como para el equipo. AVERTISSEMENT! Si vous ne reliez pas correctement cet équipement à la terre, son utilisation présente des

dangers pour la personne qui l'installe ainsi que pour l'équipement.

ALERT

ALERT! Only use components and crimping tools approved by agencies or certifying bodies recognized in your country or region such as Underwriter’s Laboratories (UL), TUV, etc.

7. For ground wiring, use a listed (approved) crimping tool to attach a listed (approved), single-hole compression lug suitable for a #10 (~5 mm) stud onto a suitable ground wire.

Ground wire should be same gauge as input wiring. Input wire size depends solely on input interruption device at the primary distribution unit (PDU).

8. If necessary, use a coarse, nonmetallic cleaning pad to clean lug and stud.

9. Telect recommends that you lightly coat anti-oxidant on lug, grounding screw, and surrounding contacting surface. Connect lug to rear panel using #10 ground provided, shown on the right. Tighten screws to 20 in.-lb (~2.26 N•m).

WARNING

WARNING! Before connecting input power cables, make sure input power to panel is turned off. WARNUNG! Vor Anschluss der Eingangsstromkabel ist sicherzustellen, dass der Eingangsstrom

ausgeschaltet ist. ¡AVISO! Antes de conectar los cables de entrada de la alimentación, compruebe que la alimentación de

entrada al panel está cortada. AVERTISSEMENT! Avant de connecter les câbles d'entrée d'alimentation, assurez-vous que l'alimentation

électrique est coupée au panneau.

10. Make sure input power is off.

11. For input wiring proximately ductors.

Input conductor (14 to 6 AWG) must match or exceed the rating of the fuse or breaker at the PDU. (Stranded wires should be tinned.)

12. Lightly coat anti-oxidant on bare conductors insert the conductors at the bottom of the screw-tight terminals, as shown on the right. Tighten screws to 16 in.-lb (1.80 N•m).

-24 Vdc and -48 Vdc always goes to -A and -B and +24 Vdc always goes to +A and +B, depending on CO or base-station power. RTN always goes to the other terminal. For Model 06004-11 with fail-safe circuitry, make sure that RTN is common to both Side A and B.

13. Make sure power is off [open breaker, dummy fuse, or vacant fuse holder at power distribution unit (PDU)] before connecting this panel’s cables to PDU.

14. Make sure that only dummy GMT fuses are install in this panel or that the GMT fuse holders are vacant.

15. Enable fuse or breaker at PDU (25A max. for Model 06004-01; 35A max. for Model 06004-11 which contains a fail-safe circuit) to turn on Feed A to Side A of panel.

16. Check voltage and polarity at input connectors of panel. Also, check that —

•The A LED on front of panel turns on (green).

•The B LED must remain red. If the A LED doesn’t turn green, recheck polarity at input connectors. (Reversing input

connections will not harm the panel.) If the input power leads were reversed, the fuse fail

FAIL RELAY

relay will fail to energize causing the normally open contacts to remain closed and normally closed contacts to remain open. If necessary, check across the FAIL RELAY alarm pins located on the rear of the panel, and shown above.

17. On the rear of the panel, with A LED lit (normal operation) — but with B LED off (failure operation) — test the Side-A FAIL RELAY pins:

• Expect continuity (0Ω) between Terminals C and NC.

• Expect an open circuit (∞Ω) between Terminals C and NO. Conversely, when testing the Side-B pins

—

•Expect an open circuit (∞Ω) between Terminals C and NC.

•Expect continuity (0Ω) between Terminals C and NO.

18. Repeat Steps 15 to 17 for Feed B and observe that the B LED turns green. Across all FAIL RELAY alarm pins —

• Expect continuity (0Ω) between Terminals C and NC.

• Expect an open circuit (∞Ω) between Terminals C and NO.

19. For output wiring

, strip off ¼ in. (~7 mm) of insulation.

Like the input terminals, the output terminals are screw-tight, wire-clamping. The output terminals will accommodate 14 AWG to 6 AWG conductors. Like the output terminals, stranded wires for outputs should be tinned.

Remember: Output conductors must be rated at or above the amperage rating of the GMT fuse. For example, use no smaller

than #16 AWG output wiring for 10A output fuses. Do not exceed 8A continuous load for a 10A fuse.

ALERT

ALERT! GMT fuses have a small inherent electrical resistance resulting in a small inherent power loss. For this reason, the GMT fuse manufacturer recommends that the lo ad for GMT fus es up to and including 7.5A not exceed 80% of the fuse rating and that the load for 10A GMT fuses not exceed 70% of the fuse rating. (For example, 10A fuse x .70 = 7A max. load). Total load for all GMT outputs on each side must not exceed 20A for a panel without a fail-safe circuit, or 15A for a panel with a fail-safe circuit.

20. Telect recommends that you lightly coat anti-oxidant on bare wires before connecting to output terminals. (NEC specifies only one conductor and load for each output terminal.) Tighten screws to 4.5 in.-lb (0.51 N•m).

21. Connect other end of output wires to load.

22. Record circuits on designation card provided, as specified by operating company procedures.(The front side of the card is shown on the right.)

The designation card has entries for Outputs 1-10 on the front and 11-20 on the rear. Use the left half of each side for Side A outputs and the right half for Side B outputs.

23. Make sure inputs at loads are disabled by removing all power cards or all input fuses at load equipment. (Always follow recommended operating company guidelines when disabling load equipment.)

WARNING

WARNING! Use only UL-listed or UL-recognized component secondary protection devices.

24. Insert the proper sizes of GMT fuses in designated fuse holders using the designation card to identify circuits. Check voltage and polarity at input of loads.

25. After all designated GMT fuses have been installed corresponding A or B LED will turn red; if an input fuse blows, the corresponding A or B LED will be orange or amber.

Again, test FAIL RELAY alarm pins on rear of panel. As before —

• Expect continuity (0Ω) between Terminals C and NC.

• Expect an open circuit (∞Ω) between Terminals C and NO.

26. If available, replace one of the output fuses with a blown fuse and check that the A or B LED changes to red. Check the FAIL ALARM pins again:

• Expect an open circuit (∞Ω) between Terminals C and NC.

• Expect continuity (0Ω) between Terminals C and NO. When finished, re-install the operable fuse.

27. Do the same with one of the input fuses. Notice that the A or B LED changes to amber. The FAIL RELA Y alarm pins will indicate a failure condition.

28. If desired

, wire-wrap remote external audio/visual alarm indicator wires (solid copper wires, #22 to #18 AWG) to the alarm terminals. See “Alarm Terminal Wiring,” in the next subsection.

29. One by one, re-enable load equipment and verify proper operation.

30. Fold designation card on the score line and slip into holder on front of panel, as shown on the right.

, check that the A and B LEDs are still green. If an output fuse blows, the

ALARM WIRING

Model 06004-01 has a standard alarm relay (FAIL RELAY) for each feed — one for Side A and one for Side B. Models 06004-11 contains the standard alarm relay plus an auxiliary relay (AUX RELAY) that can be triggered externally. All relays have two sets of Form C dry contacts for wiring to audible and visual alarm indicators.

Audible and/or visual failure indicators can be wired to the alarm pins in several ways.

—— Standard Alarms

When an input or output fuse blows the relay is de-energized and the normally open contacts close and the normally closed contacts open to indicate the failure.
