4.2 INSTALLATION
Please read completely before beginning.
4.1. Unpack and inspect the Newmar Fuse
Panel for possible damage incurred during
shipping. If damage is found, file a claim
immediately with the carrier and notify
Newmar.
4.2. Once the panel is unpacked, verify that
there are two mounting brackets. Fasten the
mounting brackets to the sides of the fuse
panel using the screws provided, such that it
will fit the rack you wish to mount the panel in.
Single rack height panels have a universal
bracket that allows the panel to be mounted
on either 19" or 23" wide equipment racks and
can be installed for flush mounting of the fuse
panel, or for a 5" offset mounting.
4.3. Mount the fuse panel on the equipment
rack using the thread forming #12-24 rack
mounting screws and lock washers provided.
WARNING: For safety reasons all wiring
should be done with the power source
removed (when possible.)
4.4. Remove the distribution fuse feeding the
input cables that are to be connected to the
new panel. Using input cables specified by
the Job Engineer, hook up the input cables to
the input terminal block on the fuse panel.
This panel has two sets of inputs. Torque _”
steel nuts to 5.5 ft-lbs.
Please be sure to observe the proper
polarity.
4.5. The battery outputs are available at the
terminals blocks at the rear of the panel. Each
fuse position is numbered and that fused
circuit is available at the terminal block
position with the same number.
4.6. All battery return (ground) connections are
terminated on the isolated battery return on
the
rear of the panel. Note that these returns are
isolated from the chassis.
4.7. For this fuse panel you have common
(C), normally closed (NC), normally open (NO)
alarm extensions (two sets of dry “C”
contacts.) You have ground activated external
alarm and battery activated external alarm
(alarms that originated outside the panel.)
4.8. CHASSIS GROUND; For safety reasons,
and as recommended by NEBS, the chassis
should be electrically connected to the rack
ground. From step 4.3. the panel should
already be ground to the rack via the #12-24
thread forming rack screws and outside tooth
lock washers. In addition to grounding via the
mounting brackets, it is recommended you
ground the chassis using a ground cable and
the #10 bolt and locks on side of chassis (#10
screw torque; 2ft/lbs or 2.7Nm.)
4.9. Power up the panel by installing the
distribution fuse supplying the panel. The
panel should power up and have no red LEDs
illuminated. Green power LEDs should be lit.
4.10. Install panel output distribution fuses as
required. Use the provided designation card
to keep a record of which equipment is
connected to which circuit and what the fuse
rating is.
4.11. If you wish to verify the Fuse alarm
circuit, you can insert a blown or open fuse
into one of the empty fuse holders. A red Fuse
Alarm LED should light on the faceplate and
the alarm extension relay should activate and
extend appropriate alarm. If you wish to verify
the EXT Alarms you can connect GND or -BAT
and the red EXT Alarm should light on the
faceplate and the alarm extension relay
should activate and extend appropriate alarm.
