Wiring Requirements for Installing the Coriolis Meter in a
Hazardous Location
Signal Cable Requirements
The 258743 Signal Cable Kit (4) supplied by Graco must be
used in hazardous locations. No cable substitution is allowed.
• The signal cable must be sealed to the meter housing per
local and national electrical code requirements, to main-
tain the meter’s flameproof or explosion proof enclosure
protection. The cable strain relief supplied is not rated for
hazardous location installation.
• Required electrical components to complete a compliant
hazardous location installation of the signal cable circuit to
the meter are not provided with the meter kit.
Power Supply Circuit Requirements
24 Vdc at 1 Amp is required to power the meter, which is more
power than an intrinsically safe circuit can provide. The 24 Vdc
can be supplied from the EasyKey.
• Installation of the power input circuit (PC) in the hazardous
location must comply with all local and national electrical
code requirements relating to flameproof or explosion
proof methods of protection.
• Required electrical components to complete a compliant
hazardous location installation of the power input circuit to
the meter are not provided with the meter kit.
Earthing
The Coriolis meter must be grounded to the ProMix 2KS fluid
panel using a minimum 12 AWG ground wire.
