Grounding
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.
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
. 3.
IG
If the resistance is greater than 25 ohms, check the
cable ground connection. Refer to F
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:
Cable Part No.
