8. POWER CONNECTION
In accordance with AS 3350.2.41 we
are obliged to inform you that this
pump is not to be used by children or
inrm persons and must not be used
as a toy by children.
The electrical connections and
checks must be made by a
qualied electrician and comply
with applicable local standards.
NOTE:
1. Ensure motor is connected
to power supply specied
on nameplate.
2. Avoid long extension leads as
they can cause substantial voltage
drop and operating problems.
3. Although the Davey Dynao electric
motor is specically engineered
to perform on a range of power
supply voltages, malfunctions
or failure caused by adverse
voltage supply conditions are
not covered under guarantee.
Single Phase
The single phase Models 6200, 6210 & 6220,
are supplied with a 10 amp plug or a special
15 amp power plug which may only be used
with the appropriate 10 or 15 amp 220/250V
power outlet (15 amp power outlets are usually
specially provided by an electrician).
Always ensure that the earth conductor in
the lead is connected to a good earth.
The Dynao single phase pump motor is
designed and manufactured by Davey specially
for this particular pump. It has no switch gear
as this motor is the P.S.C. type. The capacitor
is located inside the capacitor cover.
The Davey single phase pump motor is tted
with an inbuilt automatic reset thermal overload.
This overload is designed to protect the motor
from an overloading condition. Constant stopping
and starting of the motor by this overload would
indicate a problem to be rectied before use:
e.g. low voltage at pump (below 216 volts),
excessive ambient temperatures (above 45°C).
WARNING: Automatic reset thermal
overloads will allow the pump to restart
without warning. Always disconnect
the pump motor from the electrical
supply before maintenance or repairs.
The single phase Dynao 6220 may
also be wired to a nominal 480V power
supply, but must be reconnected at
the terminals under the motor end
cap/terminal cover, and wire in with
a contactor. In addition, the overload
tted to the pump is only suitable for
220/250V, and must be exchanged for
the 480V overload supplied.
480V OVERLOAD (where applicable)
This 240/480V single phase motor is
factory connected for use on nominal
240V AC power supply. When the
units are to be reconnected to suit a
nominal 480V supply, overload P/No.
48154 must be tted into the motor
endshield in place of standard overload.
Reconnection for 480V must be carried
out by an authorised electrician as per
wiring diagram.
Three Phase
Three phase models are designed for connection
to a nominal 415V power supply, but must be wired
with a contactor with ‘quicktrip’ overloads set at 5.2
amps for Model 6220, and 7 amps for Model 6230.
Davey recommend the use of overloads which
also have the ability to detect “single phasing” or
“dropped phase” conditions in the power supply.
Three phase Dynao models have been designed
to allow for connection either side of the Capacitor
Cover (marked “A” in gure one) on the motor.
(NOTE: Three phase motors do not have
capacitors tted in the Capacitor Cover).
This is achieved by way of either of the two
19mm access holes (marked “B” in gure one).
The access holes are designed to accept most
standard cable grommets. The unused hole can
be sealed by inserting the plug enclosed with the
pump. To connect a three phase Dynao pump
start by removing the Terminal Cover (“C”).
