NOTE! Ensure that the room where the unit is installed is well ventilated.
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 dangerous 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 which
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.
•
The ambient temperature is not to be below 0 °C (32 °F) or exceed 40 °C (104 °F). If
the ambient temperature will less or greater than these limits, contact Nederman for
more information about de-rating.
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 crush risk.
• The unit is to be anchored to the floor, particularly if it is located at a high level, to
ensure 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.

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 electrically connected to the Potential Equalizing
System (PES) on the premises.
NOTE! 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 power.
NOTE! In accordance with the European standard, the incoming 3-phase supply is to
be fitted with a hand-operated disconnecting device that conforms to the demands on
disconnectors. The disconnecting device is to be fitted within 2–3 m from FlexPAK 800/1000
and be clearly visible from the unit. Refer to local and national standards when located
outside of Europe.
NOTE! Check the continuity of the protective current circuit before the unit is used.
