Vintage Cellars FGD-0400 - Manual (Page 34)

400 is susceptible to serious damage during a lightning storm.
Depending upon the distance outdoor wiring must travel,
consideration should be given to the use of shielded wire inside a
metal conduit. Both shield and conduit should be connected to an
earth ground. This prevents stray voltage from entering the unit.

Figure 2-10. Potential Sensor Damage from Stray Electrical
Noise
2.13 Disconnecting the Model 400 for Storage or
Seasonal Use.
If you plan to employ the Model 400 as a seasonal “watchdog”
for a few months during the year, you must disconnect all wires
from the unit completely to avoid damage to the circuitry when
the unit is not in use. If the unit is unplugged but left in place with
all the sensors still connected, the wires act as antennae that draw
in any stray “electrical noise” from such devices as fans, blowers,
microwaves, etc.
Additionally, it is important to remove the batteries, or they will
discharge until they fail.
Preserve your Model 400 during the off-season, or when not in
use:
• Remove the sensor wires at the screw terminals
• Remove the batteries
• Unplug the unit and store in a safe place
