The unit is rated for connection to single-phase AC mains 120 V / 60 Hz.
Connect the unit to power mains using the pre-wired power cord with the Euro Plug
XP
.
Connect the unit to power mains through the external automatic circuit breaker
QF
with a magnetic trip. The position of the
QF
external
automatic circuit breaker must ensure free access for quick power-off of the unit. The circuit breaker trip current must correspond to the
unit current consumption, refer to the Technical data section. When selecting an automatic circuit breaker it is necessary to consider
maximum permissible wire heating which depends on the wire type, its insulation, length and installation method (i.e. overhead, in cable
ducts or inside the walls).
Connection of additional external controls
Additionally connected external controls are not included in the delivery set and must be ordered separately. Connection of additional
external control contacts are shown in the wiring diagram (dashed).
Additionally connected external controls are not included in the scope of delivery.
Connection of additional external control contacts is implemented in the control unit. For accessing the control unit open the unit door,
release the screws fixing the shielding and remove it.
Connection of the automatic fire fighting system contact (PK).
Upon connecting the automatic fire fighting system contact remove the jumper between the terminals 5 and 6.
Remove the jumper between the terminals 5 and 6.
In this case the connection is made using a normally closed dry contact that breaks the control circuit and cuts off power supply to the
unit on the signal from the fire alarm panel.
Connection of the external control unit contact (H).
The unit design enables connecting a normally opened contact (NO-contact) of external controls, such as an external CO
2
sensor, a
humidity sensor, a switch etc. The contact is connected to the terminals 7 and 8.
When the contact closes the unit switches to maximum speed.
