Mechanical Outlines
Note 1: - Chassis size 2
To allow for larger cross sections of insulated
cable on models of QFE in chassis size 2,
extended gland plates are available as an option.
Note 2: - Chassis size 3
When fitting the unit into a cabinet, allowance
must be made for 90° opening of the hinged unit
doors.
Add 90mm for the left-hand door which has the
plastic moulding incorporating the control card
and keypad, and 30mm for the right hand door
i.e. 90 + 675 + 30 = 795mm as an overall cabinet
opening.
Note 3: - Enclosures
When fitting a QFE into a cabinet, ventilation
must be provided if the heat output of the unit is
greater than the cabinet will dissipate.
Use the following formula to determine the fan
requirement. An allowance has been
incorporated into the formula so that the figure
for “Q” is the air delivery quoted in the fan
suppliers data.
An approximation of the heat produced by the
QFE (in Watts) can be made by multiplying the
full load line current by three. Exact figures for
unit full load current are in the QFE manual.
Q =

Q =
required volume of air (cubic metres per hour - m
3
/h)
Wt = heat produced by the unit and all other heat sources within the
enclosure (Watts)
t
max
= maximum permissible temperature within the enclosure
(40ºC for a fully rated QFE)
t
amb
= temperature of the air entering the enclosure (ºC)
If you prefer to work in CFM, substitute ºF for ºC. Q is now in CFM.
