NSTALLATION
WARNING: Improper installation may
result in equipment damage or personal
injury.
● Disconnect and lock out the main power supply to
equipment in the conveying system before wiring
power and communication cables between the
B32 control, vacuum receivers, pumps, dust col-
lectors and material valves.
● Install all wiring, disconnects and fuses in accor-
dance with electrical codes in your region. All
electrical installations should be done only by
qualified electrical technicians.
● Always refer to the wiring diagrams supplied with
your control before making electrical connections.
The diagrams show the most accurate electrical
component information.
● Protect communication cables from sources of
static electricity and electrical noise.
● Use shielded cable or run wire through a contigu-
ous metal conduit or wireway. Failure to use a
metal shield can expose the controls to static
electricity, which can damage electronic compo-
nents.
● Do not run communication cables near material
lines and hoses, which produce large amounts of
static electricity when conveying material.
● Keep communication cables at least 5 ft. (1.5 m)
from electric motors, transformers, rectifiers, arc
welders, generators, induction furnaces and
sources microwave radiation.
● Avoid running communication cable across power
feed lines. If you must run cable across power
lines, run the cable at right angles to the line.
Keep the cable at least 6 inches (0.15 m) from AC
power lines of less than 20 A; 1 foot (0.30 m) from
lines of 20A to 100 kVA; and 2 feet (0.60 m) from
lines of 100 kVA or more.
