WARNING
To reduce the risk of fire, explosion or electric shock:
•
The PrecisionFlo LT control unit must be electri-
cally connected to a true earth ground; the ground
in the electrical system may not be sufficient.
•
All wires used for grounding must be 18 AWG mini-
mum.
•
A qualified electrician must complete all grounding
and wiring connections.
•
Refer to your local code for the requirements for a
“true earth ground” in your area.
Read Warnings, page 6.
CAUTION
If power and grounding connections are not done prop-
erly, the equipment will be damaged and the warranty
voided.
CAUTION
To avoid control voltage differences, ensure that the
automation and PrecisionFlo LT equipment are
grounded to the same point.
