4. Guide the power cable into the connection
area such that the cable grommet fits
around the cable sheathing completely.
If necessary, seal the cable grommet on-
site.
5. Wire fan to the terminal block according to
the wiring diagram ( chapter 13). Note
the screws' tightening torque of 0.7 Nm.
EZQ../EZS..: Risk of injury if
capacitor [3] is not installed
or installed incorrectly. Even
CAUTION
slight contact with the statio-
nary impeller may cause the
motor to start.
Wire the capacitor as shown
in the wiring diagram ( chap-
ter 13).
EZQ../EZS..: Risk of damage
NOTICE
to unit if capacitor [3] is not
installed or installed incor-
rectly. Motor does not start,
runs in the wrong rotational
or air flow direction, or
overheats.
Wire the capacitor as shown
in the wiring diagram ( chap-
ter 13).
6. Wire the capacitor [3] on EZQ.. B and
EZS.. B units. Make connection on termi-
nal block [11] ( page 7), tightening the
screws to a tightening torque of 0.7 Nm.
DZQ../DZS..: Risk of damage
NOTICE
to unit if unauthorised exter-
nal control device is used.
Only use control devices with an
automatic, self-holding switch-off
function. For example, a Maico
motor protection switch MV 25
or a contactor control with self-
holding function.
7. On three-phase AC units DZQ.. and
DZS.., connect an external control device
to both TK motor terminals on the terminal
block. Note the screws' tightening torque
of 0.7 Nm.
7. Installation – Electrical connection │ EN
8. Fit an On/Off switch provided by the
customer.
9. Connect optional accessory components
( chapter 7.3 or 7.4). Refer to  cata-

7.3 EZQ.. and EZS..:
Operation with speed controller
The speed of EZQ../EZS.. units can be con-
tinuously adjusted with a TRE 5-step trans-
former, either progressively or with phase
angle control (ST, STU, STS) ( catalogue
 Internet).
The technology used in the phase
angle controller may cause humming
noises.
The fan will stop and suffer
NOTICE
functional problems if the
output voltage on the speed
controller is too low.
1. Observe information in the
speed controller operating
instructions.
2. Always set the minimum
speed on the speed controller
such that the fan motor starts
up again after power failure.
7.4 DZQ.. and DZS..:
Operation with transformer
The speed of DZQ../DZS.. units can be
adjusted progressively with a transformer
suitable for the unit type (TR 5-step
transformer) ( catalogue  Internet).
