5 Installation
NOTICE
Risk of Damage
When removing from the packaging and during trans-
port, the connection line must not be stressed or bent.
Any installation location can be chosen. The installation
must be carried out on the bearing bracket. 2 mm thick
spacers must be placed beneath the mounting flanges to
prevent abrasion of the auxiliary fan.
The operating temperatures must be adhered to, other-
wise the thermal fuse will be triggered.
The connection line must be permanently installed up to
the inlet in the on-site junction box, taking the permiss-
ible bending radius = 5 x outer diameter into considera-
tion.
The connection line must be connected in a housing that
complies with the requirements of a recognized type of
protection in accordance with EN 60079-0 section 1 if
the connection is made in a potentially explosive atmo-
sphere.
The nameplate must always remain easily legible.

6 Connection
INFO
The device may only be connected up and secured by a
trained person, taking into account the "rated voltage"
and "rated current" specified on the nameplate.
A fuse corresponding to its rated voltage (max. 3 x IB ac-
cording to lEC 60127-2-1) or a motor protection switch
with short-circuit and thermal instantaneous release (set-
ting to rated current) must be upstream of each electric
motor. In the case of very low rated currents of the elec-
tric motor, the fuse with the lowest current value accord-
ing to the specified IEC-standard is sufficient. The fuse
must be housed in the associated power supply unit or
separately upstream. The fuse rated current must be the
same as or greater than the specified maximum working
voltage of the electric motor. The breaking capacity of
the fuse link must be the same as or greater than the
maximum short-circuit current expected at the place of
installation (normally 1500 A). A connection box with a
melting fuse can be used for example.
Additional equipotential bonding is required. The ter-
minal block designated for this purpose has the ground
sign.
7 Commissioning
If the electric motor was installed according to the
guidelines specified under section Installation [}Page 4]
and section Connection [}Page 5] and it is guaranteed
that no foreign bodies can reach the rotating compon-
ents, then the electric motor can be switched on.
A thermal safety fuse is integrated that disconnects the
motor from the mains for reasons of explosion protection
in the event of external heating or blockage. This also
occurs if these installation instructions are not complied
with.
We recommend a thermostat upstream at temperatures
ranging from 40°C.
8 Troubleshooting
DANGER
Risk of fatal injury from electric current!
If contact is made with live components, there is the risk
of fatal injury.
For this reason, switch off the voltage supply, secure
against being switched on again and check that no more
voltage is present.
INFO
Repairs may only be carried out by the manufacturer
(INTERTEC-Hess) in all cases.
Do not disassemble the device! Opening the units will
render the warranty invalid.
Fault: Remedial action:
Connection
Connection line not con-
nected properly
Check connection
Mains voltage has a dif-
ferent frequency than
230-250 V AC 50 Hz
Check mains voltage and fre-
quency
Fan used for cooling:
Power supply is interrup-
ted by external thermo-
stat
Room air is cooler than the
temperature set on the ther-
mostat
Connecting cable is
damaged
The connecting cable must be
protected mechanically
Fan blade
Foreign bodies in the fan
blade
Remove foreign bodies –
make sure that the fan can
move freely

9 Directions for use
To preserve the operational capability and to prevent un-
planned downtimes of the device, please observe the
following measures:
•Bearing/drive shaft:
Both must be kept free of contamination, visual in-
spection at 3-month intervals, or at even shorter in-
tervals if necessary
•Filter mat:
When used as a filter fan, carry out regular inspec-
tions for contamination, replace if necessary
•Corrosion:
Highly aggressive media must be avoided
•Pump clean air:
If the air is very dusty, you must use a filter upstream
•Distance between rotating elements:
The distance of the rotating elements in the axial and
radial direction must not be less than 2 mm from the
fan housing.
10 Maintenance
Depending on the degree of contamination of the envir-
onment the auxiliary fan of ExVENT 30xx must be
cleaned at regular intervals to avoid overheating.
INFO
Repairs may only be carried out by the manufacturer
(INTERTEC-Hess) in all cases.
Do not disassemble the device! Opening the units will
render the warranty invalid.
11 Deinstallation
Disassembly may only be carried out by a trained per-
son.
DANGER
Risk of fatal injury from electric current!
If contact is made with live components, there is the risk
of fatal injury.
For this reason, switch off the voltage supply, secure
against being switched on again and check that no more
voltage is present.
Disconnect connection line from the clamps and from the
connection socket, disconnect device from bracket and
remove it.
12 Disposal
Disassemble the components of the product, taking the
applicable local labour protection and environmental reg-
ulations into consideration and make sure that the com-
ponents are recycled:
• Scrap metal
• Send plastic elements to recycling
• Sort other components according to their material
properties and dispose of them.
NOTICE
Environmental damage may be caused if dis-
posed of incorrectly!
Electrical scrap and electronics components are subject
to hazardous waste treatment and must only be dis-
posed of by certified specialists!
The local community authorities or specialist waste dis-
posal companies can provide information on environ-
mentally friendly disposal.
