Installation, Operating and Maintenance Instruction

12. Motor Operating Instructions Type DPIG, 2DPIG, DPIH, SEE

The following instructions must be followed
exactly, to guarantee
installation, at the operation and at the
maintenance of the motor. All persons should
be directed to the present manual which are
performing these tasks. The neglect of the
instructions can
guarantee.

12.1 Validity

This operation manual is valid for the following motors:
Model DPIG, 2DPIG, DPIH, SEE
IEC-Sizes 56 - 355.
(Additional information may be required for some
machine types due to special application and/or
design considerations).
The exact designation of the motor are shown on
the motor name plate and/or on the order
confirmation.
For all other sizes or other makes look to the
additional added operation manual of the motor
supplier.

12.2 Preparatory inspection

12.2.1 Reception check
Check all rating plate data, especially voltage and
winding connection (star or delta).
12.2.2 Insulation resistance check
Measure insulation resistance before commissioning
and when winding dampness is suspected.
Resistance, measured at 25° C, shall exceed the
reference value, i.e.
Ri [M Ω ] ≥ (20 x U) / (1000 + 2P)
where U = voltage [V]
P = output power [kW]
Windings should be discharged immediately
after measurement to avoid risk of electric
shock.
Insulation resistance reference value is halved for
each 20° C rise in ambient temperature.
If the reference resistance value is not attained,
VOGEL should be informed immediately.
In case there is too much dampness in the winding it
needs to be dried.
When drying, the heating temperature should be 90° C
for 12 - 16 hours; followed by a final drying process
lasting 6 - 8 hours at 105° C.
Drain hole plugs, if fitted, must be removed during
heating. Windings drenched in sea water normally
need to be rewound.

12.3 Scope and limits of operation

the
12.3.1 Operating conditions
The machines are intended for use in industrial drive
applications.
Normal ambient temperature limits -25° C to +40° C.
Maximum altitude 1000 m above sea level.
the
12.3.2 Safety considerations
The machine is intended to be installed and used by
qualified persons only who are familiar with relevant
safety requirements.
Safety equipment necessary for the prevention of
accidents at the mounting and operating site shall be
provided in accordance with the regulations prevailing
in the local country.
The motors are not qualified for the use in
dangerous
hazardous materials.
Small motors with supply current directly
switched by thermally sensitive switches can
start automatically.
Points to observe
the machine shall not be stepped on.
the temperature of the outer casing of the
machine may be hot to the touch during normal
operation.
some special machine applications require special
instructions (e.g. using frequency converter).
12.3.3 Maximum number of starts per hour
The diagram in chapter 6.4.3 is valid for motors with
more than 7,5 kW power of the models DPIG, 2DPIG,
DPIH, SEE.

12.4 Starting up for the first time

12.4.1 Condensate drain holes ...
Standardized motors in the frame size 90-112 do not
have drain holes. If necessary they have to be made
facing downwards according to the frame size before
mounting.
Be cautious not to damage the motor winding
when drilling the drain holes.
Motors in the frame size 56-80 and 132-315 do have
drain holes, which have to be opened from time to
time depending on their conditions of use. If they are
not facing downwards leave them closed and drill new
ones.
12.4.2 Electric supply
For the connection to the electric circuit use a switch,
which guarantees the complete separation of all
phases from the circuit.
Voltage may be connected at standstill inside
the terminal box for heating elements or direct
winding heating.
