General Considerations
Use any of three cable entries located on the bottom of the housing for
wiring access to the DL8000.
A threaded 25.4 mm (1-inch) female NPSM connection on the left
side of the unit (for AC power and control / status signals).
A spare threaded 25.4 mm (1-inch) female NPSM connection on the
right side of the unit (may be used for meter pulse wiring to
segregate meter pulse wiring from all other signals).
A threaded 50 mm (2-inch) female NPSM connection for DC
cabling and low voltage level signals in the center.
Caution
Seal all cable entries within 50 mm (2 inches) of the enclosure with
suitable sealing or potting compound.

Field Wiring Installation Guidelines:
Route external AC and DC wiring in separate conduits.
Record cable and wire routing and interconnection information to
simplify the creation of as-built documentation for the system.
Provide remote circuit breakers and optional disconnect switches for
all AC and DC power input circuits.
Follow power and signal field wiring grounding standards.
Use only stranded copper wire, equal to or of larger gauges as
indicated on the basic wiring diagrams located at the rear of this
section. Take care not to cut or weaken wire strands during the
removal of insulation.
Clearly mark all wire ends with slip-on wire tags or similar devices.
Preferably, color-code the wire tags to indicate the voltage level and
mark tags with the specific signal name.
Cut power and signal wires with an additional length of
approximately 50 mm (2 inches) for service loops to allow terminal
board and connector removal.
