4.5 OPERATION
The fan can operate in vo tage variations not exceeding 5% of the motor rated vo tage. A rating is re ated to
rated vo tage. If vo tage variations exceed 5% of the rated vo tage, the motor shou d not be started.
The fan motor has protection rating of IP 56, which prevents so ids and water from entering its inside in the
scope specified in the standard IEC 60034-5.
The motor can be used for constant operation on y, which means ight and rare start-ups not causing serious
motor heating. The use of a protection c amp depends of e ectric shock protection app ied according to
standards in force.
The following should be checked before connecting the motor:
The rated vo tage of the motor must correspond to the vo tage of a power supp y network
(network vo tage variations cannot exceed ±5 % of the rated vo tage).
Connections for correct winding on the termina box.
Mounting and continuity of the protection connection.
The motor shou d have correct over oad protection, whose current-time characteristic guarantees
that the motor wi be disconnected from the supp y vo tage in a time shorter than time tE
specified for it at a current equa to the motor starting current.
The motor iso ation resistance cannot be ess than 20MΩ in the co d state. In case when the motor
is moist (when the motor iso ation resistance is ess than 20MΩ) it shou d be dried in the
temperature be ow 353K (+ 80°C).
The motor rotation direction shou d be consistent with the rotation direction of a device being
driven; in typica motors the rotation direction is c ockwise – ooking from the motor driving side.

INSTRUCTION MANUAL
for „DELTAFAN” wa fans of the type: ***/R/*-*/**/***/Ex Page 9/14
During operation special attention should be paid to the following:
The access of coo ing air from the motor housing cannot be hindered. The housing may have worse
conducting properties due to the sticking of dust and dirt partic es to the fan surface. Therefore,
the housing surface shou d be periodica y c eaned with a cotton c oth.
During the operation specia attention shou d be paid to motor operation and immediate y
disconnect the motor from the supp y network in case of:
excessive motor vibrations,
considerab e decrease of rotationa speed,
excessive heating up of the motor or bearings.

termina box.
Power supp y cab es shou d be connected according to given diagrams and observing the fo owing conditions:
The motors are designed for the basic vo tage of 230/400V and can be connected to the network of the
inter- ead vo tage of 3x400V ±5% with the star motor winding connection (Y) or to the network of the inter-
ead vo tage of 3x230V ±5% with de ta motor winding connection (Δ).
The insta ation must have correct y se ected over oad and short-cut protection.
The insta ation must have efficient protection against e ectric shocks.
Leads of the e ectric insta ation are to be ead through iso ation bushings in the motor termina box.

.
The device shou d a ways be earthed. The fan operation without connected PE eads is forbidden. Protection
eads PE (shou d of co our ye ow-green) shou d be connected to the termina marked with the symbo .
A ways make sure that the earthing ead is onger than the power supp y ead so that it is the ast ead in case
of accidenta disconnection (tear out).
Before starting up the device, check the connections for correctness and consistency with the enc osed
e ectric diagram. Switching on the power supp y without previous checking the connections is forbidden.
The explosion-proof motors of a standard reinforced construction do not have a thermal protection.
However, the motors can be additionally protected against overheating by means of three thermistors
(one for each phase) P-(TC)120-B connected in series, whose leads-out should be connected to an external
protection circuit or to an electronic resistance relay. When the set temperature is exceeded, the circuit
should disconnect the device from the power supply network. It is recommended that the protection
circuit accounted for the temperature growth caused by multiple fan motor start-ups.
