FlexPAK
It is recommended that the unit is positioned indoors.
Under some conditions, the unit may draw air directly
into the high-pressure fan. This may cause a dan-
gerous underpressure in the room if air cannot enter
freely. There are to be two openings for ventilation,
at least 250×250 mm (10"×10") in size. One is to be
placed up high and the other one down low.
The warm exhaust air is to be directed from the unit
and out of the premises, see Figure 9 , item 4. Connect
a duct that directs the exhaust air outdoors.
The air can be directed to a heat exchanger, but there
are not to be any dampers that may obstruct the air
flow.
5.4.2 Outdoor installation
If installed outdoors, consider the following:
• The area needs to be protected from the weather.
Cover the top of the unit to protect it from snow,
rain or falling debris.
• Environmental and ambient conditions. See Sec-
tion 3.3 Technical data .
5.4.3 Moving the unit
WARNING! Risk of personal injury
• Use proper lifting and protective equipment.
• Be careful not to let the unit tip over to avoid
a crushing risk.
• The unit is to be anchored to the floor, par-
ticularly if it is located at a high level, to en-
sure that it does not move and fall down. The
frame has four holes for anchoring. Take care
during relocation and transport of the unit to
avoid tipping. If the unit is to be moved, the
frame is to be attached to the front of the
bottom frame, see Figure 10 , item 1. Before
moving the unit ensure that it is emptied of
extracted materials.
5.5 Electrical installation
WARNING! Risk of electric shock
• Work with electric equipment is to be carried
out by a qualified electrician.
• The connected wiring system is to be elec-
trically connected to the Potential Equalizing
System (PES) on the premises.
The electrical connection is NOT to be
equipped with an earth leakage circuit breaker
when the frequency converter is provided with
an EMC filter. The EMC filter function will make
the earth leakage circuit breaker shut off the
power.
Following the European standard, the incom-
ing 3-phase supply is to be fitted with a hand-
operated disconnecting device that conforms
to the demands of disconnectors. The discon-
necting device is to be fitted within 2–3 m from
FlexPAK and be clearly visible from the unit.
Refer to local and national standards when loc-
ated outside of Europe.
Check the continuity of the protective current
circuit before the unit is used.
Check that the supply voltage corresponds
to the data on the machine plate of the unit,
see Figure 1 , before connecting the unit to the
mains supply.
Control that TR1, see Figure 5 , item 2, is con-
nected to the correct voltage range and verify
its output voltage before using the unit.
Always replace worn, faulty or defective elec-
trical components with new original parts.
For the power circuit, control circuit and terminal con-
nection diagrams, see the electrical diagrams that
came with the unit. The unit is not to be connected
to the supply voltage via plug and socket but shall be
permanently connected. Ensure that all electrical con-
nections are secured properly.
5.6 General requirements
The following items are minimum requirements to en-
sure the proper function and required level of protec-
tion with regards to equipment category, the EC dir-
ectives and standards listed in the Declaration of Con-
formity:
• Take proper measures to avoid all types of electrical
stray currents to and from the duct system and elec-
trical wiring.
• Check that the input voltage and frequency to the
unit are correct.
• Operator controls shall be easily accessible.
• The need for additional emergency stop buttons
and their placement shall be analyzed according to
EN ISO 13850.
5.7 Ground check measurement
Check that the unit is properly grounded after both
the main installation and regular maintenance work. If
a component is removed and refitted, the ground con-
nection is to be verified.
5.8 Automatic bin emptying function
See the PLC Settings Manual.
