TOOLS REQUIRED
The normal electrical and mechanical tool boxes maintained in most
buildings plus a lifting deVice ("A" frame) with hooks and sling or
fork lift.
Mounting holes for the power unites) are suitable for 3/8 incn mount-
ing bolts and flat washers.
(Recommend a minimum of four bolts per
enclosure base.)
A volt-ohm meter
(VOM)
is required for verifying continuity and
making voltage measurements.
A clamp-on ammeter is required.
3.4 MECHANICAL INSTALLATION
3.4.1
Power
Unit
Refer to outline drawing for mounting dimensions and equipment
weights.
3.4.2
Pressure Sensor
The recommended installation of the sensor is pictured in
Figure 3-1.
Any installation other than the ones pictured in
Figure 3-1 may cause fa1s.e or faulty system operation due to
water turbulence, hammer or incorrect sensing.
3.4.3 Motor
Except for close coupled pumps, use of flexible couplings
between the motor and the pump, to compensate for possible
misalignment is recommended.
To minimize introducing noise into the hydraulic system, it may
be desirable to provide vibration isolation between the motor
base and the foundation, as well as flexible couplings between
suction and discharge parts of the pump and distribution piping.
3.5
ELECTRICAL WIRING AND INTERCONNECTION
All wiring shall be in accordance with the National Electrical Code
and be consistent with all local codes.
All internal electrical con-
nections between components and the power units were made at the General
Electric Factory.
When installing units, all connections should be
checked for tightness.
Connections may become loose in shipping or
storage.
A diagram showing the connections between the power unit and
the related components is furnished with each equipment.
All terminals
to which the external connections are to be made are numbered on the
equipment as indicated on the connection diagram.
The equipment should
be wired as per the interconnection diagram and verified by continuity
