NOTE: If the factory supplied cable
is removed for hard wiring the meter,
switches must be connected with
0.187” × 0.020” insulated ag termi-
nals designed for the appropriate wire
gauge for the application.
REED SWITCH MODELS
Safe operation of the reed switch is
dependent on not exceeding the
maximum wattage for that switch.
For example the normally open
reed switch has a maximum power
rating of 10 Watts. If the switch is
to operate at 24 VDC the maximum
current is found by dividing the
wattage by the voltage.

The strain relief connection on the
outside of the enclosure is water-
tight. Be sure to consult local wiring
codes before applying power. Some
installations will require rigid con-
duit. By removing the black strain
relief connections from the outside
of the enclosure, a conduit connec-
tion is accessible.
