ADVERTISSEMENT ! Avant de connecter les câbles d’entrée d’alimentation,
assurez-vous que l’alimentation électrique du panneau est coupée.
8. For input wiring— wiring used as inputs to this distribution panel — proceed as follows:
For Compression Lug Inputs
a. Crimp dual-hole compression lugs onto suitable copper
wires (#6 to #1 AWG) for BATT and RTN terminals,
Feeds A and B.
b. Remove the black plastic terminal covers, if installed.
c. Use a coarse, nonmetallic cleaning pad to clean
terminals and studs.
d. Lightly coat antioxidant on lugs, input BATTERY and
RETURN terminals, and then connect lugs to Feed A
and B input terminals on back of panel using M5 KEPs
nuts and washers provided, as shown in “Compression
Lug Inputs”. Tighten lugs to 20 in.-lb (2.25 N•m).
For Screw-Tight Inputs
a. Strip ¼ in. (0.635 cm.) of insulation from of
input cables.
b. For BATT and RTN of each feed, insert input cables
all of the way into connectors and then tighten to 14
in.-lb (~1.5 N•m).
9. Make sure power is off [open breaker, dummy fuse or open fuse holder at power distribution unit, or PDU] before
connecting this panel’s cables to PDU.
10. Make sure breakers on this panel are all off.
11. Enable fuse or breaker at PDU (60A or 125A max., depending on
conguration) to turn on Feed A to Side A of panel; check voltage and
polarity at input connectors of panel. Also, check:
• POWER ON A LED on front of panel turns on (green).
• INPUT BREAKER A LED (for a panel with optional input
breakers) turns on (green).
If not, check that input breakers on rear of panel are pressed in.
• BREAKER ALARM LED turns on (red).
• POWER ON B must be off.
12. With POWER ON A lit (normal operation) — but with POWER ON B LED
off (failure operation) —test power-fail relay and contacts at POWER FAIL terminals on rear of panel:
• Expect an open circuit (∞Ω) between Terminals C and NC.
13. Repeat Steps 11 and 12 for Feed B and observe that POWER ON B LED turns on (green).
14. Press and hold ALARM RESET on front of panel for 5 seconds to verify that all LEDs are in working order.
15. With one or all circuit breakers off, test fuse alarm relay contacts at FUSE ALARM terminals on rear
of panel:
• Expect an open circuit (∞Ω) between Terminals C and NC.
• Expect continuity (0Ω) between Terminals C and NO.
16. With both Feeds A and B on, recheck POWER FAIL terminals:
• Expect continuity (0Ω) between Terminals C and NC.
• Expect an open circuit (∞Ω) between Terminals C and NO.
17. Recheck that all circuit breakers on panel are off.
18. For output wiring, do either of the following:
• If using lugs, strip off ⅜ in. (~1 cm) of insulation from one end of copper output wires and then crimp on ring
or forked, single-hole lugs, as required by NEC. (Screw terminals will accommodate lugs for up to 10 AWG.)
• If using bare wire, strip off 5/8 in. (~1.5 cm) of insulation. (Stranded wires should be tinned.)
Remember: Output wires must be rated at or above the amperage rating of the output circuit breaker. For
example, use no smaller than #12 AWG output wiring for 20A output fuses. Do not exceed 16A continuous
load for a 20A breaker.
ALERT! Local electrical and operating company guidelines recommend that the individual load not exceed 80%
of circuit breaker capacity (for example, 10A breaker x .80 = 8A max. load). Total load for all breaker outputs
on each side must not exceed —
• 40A for a panel with an optional thermal input breaker
• 50A for a panel having screw-tight inputs connectors, but without an optional thermal input breaker
• 100A for a panel having compression input connectors, but without an optional thermal input breaker
19. Clean output terminals and lugs with a nonabrasive, nonmetallic pad.
20. If installed, remove covers over output and alarm connectors.
21. Telect recommends that you lightly coat antioxidant on lugs and output BATTERY and RETURN terminals before
connecting lugs/wires to outputs. (NEC species only one lug and load for each output terminal.) Tighten screws to 9
in.-lb (1.01 N•m).
22. Connect other end of output wires to load.
23. Use designation labels (supplied) to record outputs, as specied by
operating company standard installation procedures.
24. 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.
25. One by one, turn on circuit breakers on this panel and check voltage
and polarity at input of loads.
26. With all circuit breakers on, the BREAKER ALARM LED must go off.
Test fuse alarm relay contacts at FUSE ALARM terminals on rear of panel:
• Expect continuity (0Ω) between Terminals C and NC.
• Expect an open circuit (∞Ω) between Terminals C and NO.
27. Switch off one of the circuit breakers to simulate a tripped breaker.
Again, the BREAKER ALARM LED should light.
28. Press ALARM RESET on front of panel.
BREAKER ALARM LED should go off again. (Pressing ALARM RESET will reset the BREAKER ALARM LED on
front and clear FUSE ALARM on rear of panel.) Recheck FUSE ALARM terminals and expect the same status as in
Step 26 with all breakers on.
29. If desired, connect remote external audio/visual alarm indicator wires (solid or tinned wires, #30 to #16 AWG) to the
POWER FAIL and FUSE ALARM terminals.
30. One by one, re-enable load equipment and verify proper operation.
31. Reinstall covers over output and alarm terminals.
Replacing Output Circuit Breakers
ALERT! Although difcult to remove from the panel, circuit breakers can be disconnected and replaced.
1. Be sure new breaker is the same size as breaker being replaced.
2. Place new breaker within easy reach of panel. Be sure new breaker is off ( O ) position.
3. If possible, turn off all breakers on the side (A or B) where the breaker is to be replaced. Then, turn off input power to
that side of panel.
4. Place breaker to be replaced in the off position.
5. Using a very small, at-tipped screwdriver, carefully pry out on bottom of breaker while applying upward force on face
of breaker.
This should raise the bottom of the breaker so it slightly protrudes out the front of the panel.
6. While preventing breaker from going back into panel, depress bottom tab with the screwdriver and pull out on breaker.
This starts the tab through the panel front opening so that it is dislodged about 1/16 in. (~.15 cm) at the bottom.
7. While pulling on breaker, work the screwdriver at the top to release the top tab.
If both tabs are released, the breaker should begin to pull out the front of the panel.
8. The breaker conductors can be pulled loose from the assembly at the rear of the panel. Do not pull out on the breaker
more than necessary when removing and installing the LOAD and LINE connectors.
9. Gently work breaker out front of panel until rear connectors can be accessed
by pliers.
10. Remove LOAD connector from breaker using needle-nose pliers:
• For standard circuit breaker installations, with “O” at the top and “|”
at the bottom, the LOAD connector will be near the bottom.
• For circuit breaker installations with “|” at the top and “O” at the
bottom, the LOAD connector will be near the top.

11. Restrain connector to prevent it from traveling back into the panel.
ALERT! The LINE side connection of the breaker has live VDC. Do not allow contact of the connector (or tools
holding the connector) to grounded ironwork or panel chassis.
12. While holding breaker out from the front of the panel, grasp LINE connector of breaker with needle-nose pliers.
13. Hold the LINE connector with pliers and then pull breaker, wiggling it until breaker is free from connector. Continue to
hold the LINE connector with the pliers. Do not allow the connector to contact the panel chassis.
14. With your free hand, pick up new breaker and check orientation of new breaker.
15. Press spade connector of new breaker into the pliers-held LINE connector until fully seated.
Visually inspect the connection to be sure full contact is made between the LINE connector and the breaker
spade connector.
16. Place the LOAD conductor connector on the LOAD spade connector of the breaker. Visually inspect the connection.
17. Gently place breaker back into panel. Push on front of breaker until tabs are cleared and breaker is secure in panel.
18. If input power was turned off, restore input power and turn on breakers one at a time.
19. When new breaker is turned on, check output terminal for correct polarity.
