Grounding
1. Ground the flow meter by connecting a grounded
cable to the meter housing or sensor.
Have a qualified electrician check the electrical
grounding continuity between the flow meter sensor
and a true earth ground; remove the cable connec-
tor from the sensor and measure the resistance
from the cable connector Pin 2 to true earth ground.
Refer to F
IG
. 3.
If the resistance is greater than 25 ohms, check the
cable ground connection. Refer to F
IG
. 3. Reconnect
the ground sheath or replace the cable. Do not oper-
ate the system until the problem is corrected.
2. Always ground the meter, using one of the following
options:
a. Mount the meter to a grounded conductive sur-
face, or
b. Connect the conductive fluid hose to the meter
inlet and outlet, or
c. Connect a ground wire to the meter's M6
mounting holes.
3. Never use the flow meter with an electrostatic gun
isolation stand.
Meter Cables and Adaptor
See Table 1 for available meter cables or the adaptor for
use with cables with a black plastic connector and a
replacement sensor.
The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric or
static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.

24Y434 Adaptor - Not included with cables (see note)
NOTE : These cables have a metal connector, which will only mate with a sensor that
also has a metal connector. Adaptor 24Y434 is required to connect an existing cable
with a plastic connector to a replacement sensor, which has a metal connector.
Adaptor 24Y434 purchased separately.
