ment. Consider all necessary weatherproofi ng material
or sealant when doing so.
Use the corner holes to affi x the unit to the base/frame
EN
on the roof with bolts or studs.
In case ductwork or accessories are to be connected to
the intake side of the fan, the lower area of the unit pre-
sents a fl at fl ange provided with all necessary bolts. If
fl exible connectors are to be installed, these shall be sui-
table for high temperature and must be taught to ensure
no disruption to air fl ow or vibrations.
3.3. ELECTRICAL CONNECTION
The electrical connection of this unit is divided in two
parts: actuators for the HATCH, and the motor of the
FAN. For both parts the diagrams provided inside their
respective terminal boxes shall be followed.
See "commissioning" section for more information on
the activation sequences.
HATCH
The HATCH cover is operated by two 220-240V IP65 ac-
tuators, which may indicate the fully open / fully closed
position.
Remove the cover of the terminal box to carry out the
connection as shown in the following diagram.

The "OPEN QUICKLY" connection is preferable, particu-
larly for emergency smoke extract scenarios. The SZ and
SA contacts are for "open" and "closed" position respec-
tively, for remote monitoring. Note these signal only the
fi nal position of the cover, not while in transition from one
position to the next.
FAN
The terminal isolator box is supplied with a cable gland
for typical electrical power cable connection, to assist
installation. However, if installer uses a cable requiring
a differing cable gland, this is to be supplied by the Ins-
taller, no alternative is offered by S&P. The Installer is
responsible to ensure that cable, and cable gland, are
suitable and safe for application according to country re-
gulations.
Ensure system operation is safe in event of power cut/
power outage/disruption to power supply. If ventilation is
stopped due to disruption to power supply, ensure no risk

due to excessive temperature (electrical heater). Care
may be needed when restarting fan after disruption to
power supply.
Motor protection is to be provided by the installer.
Ensure the isolator is in OFF position before and after
carrying out the connections, in order to prevent sudden
activation while the HATCH cover is closed. Carry out the
connections following the wiring diagram affi xed to the
inside of the box's cover.
The fan motor power supply must be designed to accom-
modate any motor protection devices, where applicable,
for S1 duty cycle. Ensure these devices are fi tted and
operating correctly.
However, for emergency smoke extract the fan is desig-
ned and certifi ed to run at the stated temperature and
time, or to destruction. Therefore, all motor protection
devices must be disabled or bypassed under such event.
This also applies to TGT-HATCH, if it will operate as a
fresh air supply fan during a fi re emergency scenario.
Power supply should be via a protected source to ena-
ble fan to run under emergency fi re smoke conditions.
In case a VSD is used for normal ventilation, it shall be
bypassed in this scenario, leaving the fan in Direct on
line supply. This will not be necessary if the VSD used
is included in the fi re rating certifi cate of the unit, or the
specifi cations detailed in EN 1210-3 are complied with.
Motors with speed control via Variable Speed Drive
(VSD) Frequency Inverter, should not be run in excess
of nameplate speed. In general applications, we recom-
mend not to run at less than 40% of nameplate speed
(20Hz) without reference to manufacturer, since this
may damage the unit.
Consider the addition of sinusoidal or EMC fi lters de-
pending on cable length from VSD to the terminal box.
4. COMMISSIONING
4.1. PRIOR
• If the fan is accessible to operators and there is a heal-
th and safety risk, adequate protection must be fi tted;
information for safety equipment, including guards,
can be found in S&P accessories catalogue.
• Ensure the isolator is in OFF position.
• Check fan equipment name plate data is appropriate to
the location electrical supply, especially Voltage, Fre-
quency, Phase, Amps, speed are correct. All safety and
protection devices have been fi tted and are functional.
• Check earth connections, electrical terminations and
terminal box lid, with any seals, if fi tted, are correct.
• Check all rotating parts have free, unobstructed mo-
vement.
• Check there are no foreign bodies inside the fan or that
can be drawn into, or fall into fan.
• Check the structure is complete and has no damage.
• Check installation and area is safe.
• Check all aspects regarding fi re safety are compliant
with local applicable regulations, that all procedures
