Installation
3. Centering
Though the pump and driver have been centered in
the factory, the common bed may be distorted when
the foundation bolts are inserted during installation.
Adjust by placing tapered liners underneath the
bed, and center so that the shaft coupling is within
the range indicated in fig. 2.
To center a pump that has been purchased without
a driver and which is to be directly driven, insert
liners under the drive, and center so that the shaft
coupling is within the range indicated in Fig2.
CAUTION
The coupling guard must be removed to make centering adjustment. Be sure to replace before beginning
operation.
CAUTION
Measure the insulation resistance. The value should be more than 1 mega ohm. While making
The measurement, keep the power supply cable off the ground.
CAUTION
Before installation check rotation. Correct rotation is clockwise when viewed from motor side.
Read ELECTRICAL WIRING.
4. Electrical Wiring.
(1) Refer to
Fig. 3 for correct wiring It is important that
wiring be correct and that motor is properly
grounded.
(2) Check the following points before turning on
operation switch :
1 Is the fuse the right type ?
2
Is the wiring correct ?
3 Has motor been grounded ?
4 With a three-phase motor check for a loose or
completely detached connection Operating on
only two terminals will result in phase omission,
causing motor burn out.
(3) Terminal voltage in motors bearing the EBARA
nameplate may be within
±
10% of the rated
voltage exceeding this range will lead to breakdown
(4) Overloading the motor beyond the prescribed limit
will reduce its efficiency, is not economical and will
eventually lead to motor malfunction.
We recommend that a protective motor relay be in-
stalled to prevent burnout caused by overloading.

WARNING
Check that the power is locked off and disconnected before working on pump.
All electric work should be performed by a qualified electrician and all notional
and local electrical codes must be observed.
