3-3 APPLY POWER TO THE UNIT
Once the leak detection cable is connected to the unit, power may be applied.
The LD5000 operates on 85-264VAC power. An AC power supply should be run to the location of the
unit. Before applying power to the unit, make sure the AC breaker switch is turned off.
Once the power is turned off, strip the end of the AC supply so the three wires inside are exposed. Strip the
end of each of the three wires and feed the end of the power supply into the LD5000 enclosure. The three
wires must now be inserted into the terminal block in the lower right corner of the enclosure. As is labeled
in the enclosure, the live power line is placed inside the left hand opening of the terminal block. The Earth
ground line is placed into the terminal block’s center station. The neutral line is placed into the opening on
the right side of the terminal block.
Once all the wires are placed inside the terminal block, tighten the three screws across the bottom of the
terminal block until the wires are securely held in place. Turn the AC supply back on. Flip the LD5000’s
power switch on to activate the unit. Wait approximately one minute. No alarm should be present.
On the LCD, enter the Status menu. Press Enter (
↵) twice. The cable length is displayed. If this reading
varies by more than ±5% of the actual length of cable installed, verify the installation.
Use the switch settings on page 8 to set the cable length scale for the analog 4-20mA loop. Set the clock,
system name, relay configuration, feet/meters, LCD setup (re-alarm time, password), etc.
Wait at least 30 minutes before calibrating the LD5000. Calibrate the LD5000 through the front panel
Setup Menu (page 14) or through the RS-232 configuration port System Configuration Menu (page 33).
Auto calibration is recommended.
Map the cable per the instructions in Chapter 8: Mapping the Cable beginning on page 21.
Warning!
• A dedicated circuit breaker must be provided in the building within
close proximity to the RLE unit and be clearly marked as the
disconnecting device for this unit.
