1.1
PURPOSE OF MANUAL
1.1.1 This manual is furnished to acquaint you with some of
the practical ways to install, operate, and maintain
this unit. Read it carefully before doing any work on
your unit and keep it handy for future reference.
1.1.2 Equipment cannot operate well without proper care.
To keep this unit at top efficiency, follow the recom-
mended installation and servicing procedures outlined
in this manual.
1.1.3
1.1.4 Your Technologic 350 Pump Controller should have a
safety instruction decal (Part # S11550). If the decal is
missing or illegible contact your local B&G represen-
tative for a replacement.
1.2
ADDITIONAL SAFETY REQUIREMENTS
1.2.1 Motor must have a properly sized starter with properly
sized overload block to provide overload and under-
voltage protection. Ground fault protection should be
sized properly.
1.2.2 Refer to the motor manufacturer’s I.O.M. for specific
installation information.
1.2.3 Even when the motor is stopped, it should be con-
sidered “alive” as long as its controller is energized.
Keep hands away from the output shaft until the
motor has completely stopped and power is discon-
nected from the pump controller.
1.2.4 The use of motor disconnect switches is acceptable.
1.2.5 Motor control equipment and electronic controls are
connected to hazardous line voltages. When servicing
electronic controls, there will be exposed components
at or above line potential. Extreme care should be
taken to protect against shock. Stand on an insulating
pad and make it a habit to use only one hand when
checking components. Always use accurate test
meters when checking electrical components. Always
work with another person in case of an emergency.
Disconnect power when performing maintenance. Be
sure equipment is properly grounded. Wear safety
glasses whenever working on electronic control or
rotating equipment.
1.3
STORAGE
For long periods of storage, the unit should be covered
to prevent corrosion and contamination from dirt. It
should be STORED in a clean, dry location between
-20 and +75°C. The relative humidity should not ex-
ceed 85%. The unit should be checked periodically to
ensure that no condensation has formed. After stor-
age, again check that it is dry before applying power.
1.4
HANDLING
Care should be taken to prevent damage due to drop-
ping or jolting when moving the Technologic Pump
Controller. Transportation damage should be brought
to the carrier’s attention immediately upon receipt.
1.5
TEMPERATURE AND VENTILATION
All electrical equipment is susceptible to failure if
operated in ambient temperatures outside of its rat-
ing. The OPERATING temperature range for this unit is
0 to 40°C. The relative humidity should not exceed 95%
non-condensing. The unit should not be operated
outside these extremes.
1.6
GROUND CONNECTIONS
A grounding terminal is provided for a dedicated
ground wire connection. All provisions of the National
Electrical Code and local codes must be followed.
1.7
POWER WIRING
Power wire types and sizes must be selected based
upon conformance with the National Electrical Code
and all local codes and restrictions. In addition, only
copper (Cu) wire rated for 75°C (minimum) may be
used for the power connections. Refer to the input
current as listed on the nameplate on the enclosure
door when sizing wire.
SAFETY INSTRUCTION: This safely alert
symbol will be used in this manual and on the
unit safety instruction to draw attention to safety
related instructions. When used the safety alert
symbol means
ATTENTION, BECOME ALERT!
YOUR SAFETY IS INVOLVED! FAILURE TO
FOLLOW THIS INSTRUCTION MAY RESULT IN
A SAFETY HAZARD.
WARNING: Motor can start automatically. Keep
hands away from output shaft until motor is com-
pletely stopped and input power is removed from the
motor control panel. Lockout main power switch while
working near the motor shaft.
Failure to follow these
instructions could result in serious personal injury,
death, and/or property damage.
DANGER: Troubleshooting live control panels exposes
personnel to hazardous voltages. Electrical trouble-
shooting must only be done by a qualified electrician.
Failure to follow these instructions could result in seri-
ous personal injury, death, and/or property damage.
WARNING: Prevent electrical shocks. Disconnect the
power supply before beginning installation.
Failure to
follow these instructions could result in serious per-
sonal injury, death, and/or property damage.
WARNING: Conduit grounds are not adequate. A
separate ground wire must be attached to the ground
lug provided in the enclosure to avoid potential safety
hazards.
Failure to follow these instructions could re-
sult in serious personal injury, death, and/or property
damage.
