Overview
The Amphenol Network Solutions nrg600BT08-M 600A dual-feed 8/8 circuit breaker/TFD Load Center with 5 GMTs features -48V
operating voltage to fit in legacy and “next-gen” network applications, with advanced circuit level monitoring features engineered into a
4RU footprint. Each of the dual feeds contains eight positions for either bullet-style breakers or TFD fuse holders. Each of the dual feeds
also includes five GMT fuses, providing ample capacity for distribution to a broad range of components.
The panel provides total front access to fuses and LED status. Below the status LED console is a pull-out designation card holder.
All terminals for inputs, outputs, ground and alarms are on the rear of the panel. All terminals are covered by a single full-width
transparent terminal cover:
• Inputs are studs for dual-hole lugs.
• Ground terminals are dual, threaded holes for ground bolts.
• Output studs for dual-hole lugs and screw posts for GMTs.
• Power/fuse alarm terminals are wire wrap pins.
The bullet terminals can accept either TFD fuse holders or bullet terminal breakers. Single pole, double pole and triple pole breakers
are
also supported.
The GMT fuse holders are mounted inverted so that the GMT indicator flag flips downward when tripped, making identification and
detection easier, especially on taller racks. In addition, the GMT fuse holders/ sensors are generously spaced for easy grip of fuses
and better heat dissipation.

Important Installation Guidelines:
• Elevated Operating Ambient Temperature :: If you install the
rack in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room
ambient. Therefore, take care to install the equipment in an
environment compatible with the maximum operating temperature.
• Reduced Air Flow :: Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of the
equipment is not compromised.
• Mechanical Loading :: Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
• Circuit Overloading - Give consideration to the connection of the
equipment to the supply circuit and the effect that overloading of the
circuits might have on overcurrent protection and supply wiring. Use
appropriate consideration for equipment nameplate ratings when
addressing this concern.
• Reliable Earthing :: Maintain reliable earthing of rack-mounted
equipment. Pay particular attention to supply connections other than
direct connections to the branch circuit (e.g., use of power strips).
• Disconnect Device :: Incorporate a readily accessible disconnect
device in the building installation wiring.
Inspection
Please read and understand all instructions before starting installation.
If you have questions, contact Amphenol Network Solutions Technical
Support at [e-mail] or call 509.926.6000.

Installation
ALERT! It is recommended that this product is installed within a restricted
access location where access is through the use of a tool, lock and key, or
other means of security and is controlled by the authority responsible for
the location. This product must be installed and maintained only by
qualified technicians.
Verify all connections meet requirements specified in local electric codes
or operating company guidelines before supplying power. Unit shall be
protected by a listed circuit breaker or branch-rated fuse sufficient to
interrupt power levels specified on the preceding page.
Rack Mounting
• The nrg600BT08-M panel can be mounted in 19-in. & 23-in. EIA and
WECO racks.
• The nrg600BT08-M panel can be flush-mounted, 2-in extended or
4-in extended.
1. Use the 12 screws provided to fasten the brackets to the panel.
2. Locate an unused rack position and mount panel using at least four
sets of fasteners (screws, flat washers and star washers provided) per
side. It’s best to mount the panel as high as possible on the rack.
3. Tighten screws to 35 in.-lb (4.29 N•m). Amphenol Network
Solutions recommends using a seismic rack for best rigidity. Also,
if you intend on installing more than one panel per rack, you need
to plan a rack arrangement that dissipates heat efficiently.
4. Loosen (you need not remove) four screws securing transparent
terminal cover to the rear of the panel.
5. Remove the cover.

WARNING! Failure to properly ground this equipment can create
hazardous conditions for installation personnel and for the equipment.
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.
6. Use a listed (approved) crimping tool to attach a listed (approved),
dual-hole compression lug for 1/4-20 studs on 5/8-in. centers onto #2
AWG ground wire.
7. If desired (highly recommended), lightly coat antioxidant onlug,
grounding terminal and surrounding contacting surface.
8. Connect the lug using the 1/4 -20 bolts, lock washers and flat
washers provided.
9. Tighten bolts to ~50 in.-lb (~5.6 N•m), max.
10. Make sure the power is off (open breaker, dummy fuse or open fuse
holder at primary power distribution unit, PDU or battery) before
connecting this panel’s input cables to a PDU or battery.
12. Insulate lug barrels with UL94 V-0-rated heat-shrink tubing.
13. Clean terminals and lugs with nonabrasive, nonmetallic pad.
14. If required, lightly coat antioxidant on lugs and input BATT and
RETURN terminals, and then connect the lugs to input terminals on
the back of the panel.
15. Tighten lugs to 150 in.-lb (~17 N•m), max.
16. Make sure all interrupter positions are either empty, off or contain
dummy fuses (phoney, inoperative all-plastic slugs).
ALERT! Only qualified service personnel should replace fuses. The
installer must verify that a readily accessible protection device is
incorporated in the building wiring feeding the panel: 750A (max.)
protection device for a 600A panel.
WARNING! Before connecting input power cables, make sure the
input power to the panel is turned off.
11. For input wiring - wiring used as inputs to this load center:
• Crimp dual-hole compression lugs onto #1 AWG to 750MCM copper
wires. The choice of input wiring depends on the following criteria:
• Input interrupt device rating affects the size of input wiring.
• Ambient operating temperature affects the type of input wire
insulation. For further information consult the National Electrical
Code (NEC).

Boot Loader Mode
The nrg600BT08-M alarm card will receive remote firmware updates automatically from the nrgCONTROL-BT. The boot loader mode is indicated by a
yellow PWR A LED. In this mode, the power and fuse LEDs are used for diagnostics and do not represent the power and fuse status. A blinking green
PWR B LED in conjunction with the yellow PWR A LED indicates the firmware is actively being updated. The update process lasts approximately
7 seconds.
NOTE: The following steps require that the nrg600BT08-M is connected to an nrgCONTROL-BT controller. The nrgCONTROL-BT provides power to
the nrg600BT08-M’s alarm card, which is required for steps 17-19 and steps 22-27. Reference the nrgNET connectivity section for further details.
17. Enable protection device (fuse or breaker) at primary PDU to turn on Feed A to Side A of panel and then check voltage and polarity at input
connectors of panel. Also, check:
• PWR A LED on front of panel turns on (green).
• PWR B LED is off
18. With PWR A LED green (normal operation) — but with PWR B LED off — test power-fail relay and contacts at PWR alarm terminals on rear
of panel:
• Expect open circuit (∞Ω) between Terminals C and NC.
• Expect an continuity (0Ω) between Terminals C and NO.
19. Also, test fuse alarm relay contacts at fuse (CB/Fuse Alarm) terminals on the rear of the panel:
• Expect continuity (0Ω) between Terminals C and NC.
• Expect an open circuit (∞Ω) between Terminals C and NO.
20. Repeat Steps 17 through 19 to power up Side B. PWR A and PWR B LEDs must both be green.

ALERT! GMT fuses have a small inherent electrical resistance
resulting in a small inherent power loss. For this reason, the GMT
fuse manufacturer recommends:
• The load for GMT fuses up to and including 7.5A not exceed 80%
of the fuse rating.
• The load for GMT fuse sizes between 10A and 20A not exceed
70% of the fuse rating. For example, the load for a 15A GMTfuse
should not exceed 10.5A (15A x 0.70 = 10.5A).
29. Make sure load devices are off (disabled) and then install GMT fuses.
Remember, GMT fuses need to be installed inverted so that failure
indication flags are at the bottom.
30. Test power and polarity at input of each equipment load.
31. If possible, replace one of the operable GMT fuses with a blown fuse
to verify that the applicable FUSE Alarm LED turns red. Also, check
the FUSE alarm terminals on the rear of the panel:
• Expect an open circuit (∞Ω) between Terminals C and NC.
• Expect continuity (0Ω) between Terminals C and NO. Reinstall
operable GMT fuse before proceeding.
• If desired, connect remote, external audio/visual panel alarm
indicator wires (solid wires, #22 to #18 AWG) to wire wrap PWR
and FUSE alarm pins on rear of panel, as shown in Figure 5.
32. Reinstall terminal cover.
33. Lastly, enable equipment loads one at a time to verify the proper
operation of loads.
34. The total load for all GMT fuse and bullet terminal outputs on each
side must not exceed the panel’s load rating: 600A.
