This kit includes the parts necessary to maintain the
intrinsic safety of the ProMix unit when a printer is
installed in a non-hazardous location.
WARNING
FIRE, EXPLOSION, AND ELECTRIC
SHOCK HAZARD
The ProMix control is intrinsically safe
when used without any external electri-
cal components connected to it. If an
external printer is connected to the
control, the control is no longer intrinsi-
cally safe without the use of this kit.
Do not install or service this equipment
unless you are trained and qualified. All
wiring and electrical troubleshooting must be done
by a qualified electrician. Follow the Grounding,
Wiring and Safety Requirements below .

ground lug (C) and true earth ground. The resis-
tance should be less than 1 ohm.
If the resistance is above 1 ohm, check grounding
connections and the ground wire for damage.
Reconnect or replace the ground wire. Do not
operate the system until the problem is corrected.
