should have a safety instruction decal (Part #S11550).
If the decal is missing or illegible contact your local
B&G representative 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 consid-
ered "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.
WARNING: Motor can start automatically. Keeps
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.
1.2.4
Motor control equipment and electronic controls are
connected to hazardous line voltages. When servic-
ing electronic controls, there will be exposed compo-
nents at or above line potential. Extreme care should
be taken to protect against shock. Stand on an insu-
lating 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 emer-
gency. Disconnect power when performing mainte-
nance. Be sure equipment is properly grounded.
Wear safety glasses whenever working on electronic
control or rotating equipment.

DANGER: Troubleshooting live control panels ex-
poses personnel to hazardous voltages. Electrical
troubleshooting must only be done by a qualified electri-
cian. Failure to follow these instructions could result in
serious personal injury, death, and/or property damage.
1.3
STORAGE
For long periods of storage, the unit should be cov-
ered 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 exceed 85%. The unit should be checked period-
ically to ensure that no condensation has formed.
After storage, again check that it is dry before apply-
ing power.
1.4
HANDLING
1.4.1
Care should be taken to prevent damage due to
dropping or jolting when moving the unit. Inspect the
unit thoroughly for damage upon receipt.
Transportation damage should be brought to the car-
rier's attention immediately. Ensure that sensing lines
are free of crimps and kinks.
1.4.2
The units should be unloaded and handled by quali-
fied personnel. The unit is top heavy due to the posi-
tion of the motors. Use the motor eyebolts to stabilize
the unit while lifting to prevent overturning. Do not
use the motor eyebolts to lift.
WARNING: Falling Objects Hazard. Eyebolts or lift-
ing lugs, if provided, are for lifting only the compo-
nents to which they are attached. Failure to follow these
instructions could result in serious personal injury,
death, and/or property damage.
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 oper-
ated outside these extremes.
WARNING: Prevent electrical shocks. Disconnect
the power supply before beginning installation.
Failure to follow these instructions could result
in serious personal injury, death, and/or property
damage.
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.
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 result in serious personal injury, death, and/or
property damage.
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.
