Disconnect the fan from power mains prior to any connection, adjustment, maintenance
and repair operations.
Mounting and wireworks are allowed only by a duly qualied electrician with valid
electrical work permit for electric units up to 1000 V after careful reading of the present
user's manual.
The fans are not ready-to-use products and are allowed for operation only after connection
to air ducts and installation of protecting grilles.
Connect air ducts on both sides of the fan.
In case of the fan mounting outside protect the fan against water ingress.
For example, install the fan under the protecting outer hood.
Before connecting the fan to power mains make sure of no visible damages of the fan
impeller, casing, grille and no foreign objects inside the casing that can damage the impeller
blades. Misuse of the fan or any unauthorized modications are not allowed. Do not use
the fan for explosive and re-hazardous media. Take steps to prevent gas backdrafting
from the devices that operate with gas or open ame. The fan may have sharp edges. Make
steps to avoid being cut.
SAFETY REQUIREMENTS

14
VKP / VKPI / VKPF / VKPFI / VKP EC / VKPI EC
The fan is designed for mounting and operation in any position. In case of ceiling mounting
the fan is recommended to be mounted with the motor cover downwards to facilitate
access to the terminal box.
Check the fan power cables for integrity and make sure the impeller has smooth rotation
prior to mounting.
Install exible connectors on both sides of the fan. Air ow direction in the system must
match the direction of the arrow on the fan casing.
Remember to mount the fan on the additional internal brackets to avoid load transfer to
the exible connectors. The most suitable mounting option is xation of the fan to the
ceiling with anchor bolts or suspension of the fan to the perforated metal plates. Apply
self-adhesive sealer on the fan end surfaces prior to mounting. Connect the fan to air ducts
with M8 bolts and nuts.
Provide reliable mounting of the fan!
Connect the terminal PE to the ground circuit.
Due to constant improvements the design of some models may slightly dier from those
described in this manual.

CONNECTION TO POWER MAINS
Disconnect the fan from power mains prior to any operations with the fan.
Connection of the fan to power mains by duly a professional
electrician only!
The rated electric parameters of the fan are shown on the factory sticker.
Any tempering with internal connection is not allowed and will void
warranty.
Depending on the fan type it is rated either for single-phase ac 230 V/50/60 Hz or three-
phase ac 380-400 V/50/60 Hz power mains.
Connect the fan to power mains through insulated, durable and thermal resistant
conductors (cables, wires).
The automatic circuit breaker incorporated into the xed network that breaks all the phases
must be installed at the external electric input 230V/50/60 Hz or 380-400 V/50/60Hz. The
external circuit breaker QF location must provide free and unhampered access to the fan
for quick switching o in case of need.
The overcurrent protection must match the rated current consumption of the fan. The
recommended rated current of the automatic circuit breaker and wire cross section of
various fan types are stated in the table stated on page 16. The stated wire cross sections
are for reference only. The actually required wire cross section depends on the cable type,
insulation, length and its layout way - open, channel or wall mounting.
Connect EC-fans to power mains on the terminal block located in the external or integrated
terminal box following the wiring diagram and terminal designation. The sticker with the
terminal designation is inside the terminal box.
The terminals TW1, TW2 (TK1,TK2) are the lead-out terminals of the overheating
thermostat normally closed contact. Connect this terminal in series to the power circuit
of the magnetic starter KM1 that starts the motor after pressing the button S1. In case of
the motor overheating the motor contact breaks and switches the starter coil o to de-
energize and stop the motor.
The automatic circuit breaker QF, the magnetic starter KM1, the control buttons S1 and S2
are not included into the delivery set and are to be mounted by the customer.
