1.2.4 The use of motor disconnect switches is acceptable.
Consult the factory for proper interlocking with
adjustable frequency drives, AFD’s. See Section 1.9.
1.2.5 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.
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 +60ºC. 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.
NOTE: EXTENDED STORAGE OF AFDs MAY
REQUIRE SPECIAL ATTENTION PRIOR TO START-
UP. SEE MANUFACTURER’S I.O.M. FOR DETAILS.
1.4 HANDLING
Care should be taken to prevent damage due to
dropping 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 operat-
ed outside these extremes.
1.6 INPUT VOLTAGE
The AFD and Technologic Pump Controller can be
set up to operate across a broad range of voltages. It
was factory set to operate on the voltage shown on
the nameplate. Check the AFD nameplate for the
proper input and output voltages before wiring the
AFD.
The voltage tolerance is +10/-5% and phase to
phase voltage must not have an imbalance greater
than 5 VAC.
1.7 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.
1.8 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.
1.9 OUTPUT/MOTOR DISCONNECT
It is necessary that any device which can disconnect
the motor from the output of the AFD be interlocked
to the emergency shutdown circuits of the AFD. This
will provide an orderly shutdown if the disconnecting
device is open circuited while the AFD is in operation.
Failure to provide this interlock may result in dam-
aged components due to improper installation.
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 haz-
ards. FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN SERIOUS PERSONAL INJURY,
DEATH, AND/OR PROPERTY DAMAGE.
CAUTION: Metal filings can create electrical short
circuits. Do not drill, saw, file or perform any opera-
tion on the AFD conduit entry plate while attached to the
AFD. FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN PROPERTY DAMAGE AND/OR
MODERATE PERSONAL INJURY.
DANGER: Troubleshooting live control panels exposes
personnel to hazardous voltages. Electrical trouble-
shooting must only be done by a qualified electrician. FAIL-
URE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
WARNING: Prevent electrical shocks. Disconnect
the power supply before beginning installation. FAIL-
