RCD fault-current circuit breaker
All devices are installed with a protective conductor terminal. It may also be
necessary to include a RCD fault-current circuit breaker when installing the de-
vice to comply with country-specific standards and regulations.
Device size 6 half size GN to 20 full size GN
Connect the device to a type B fault-current circuit breaker (RCD type B).
Device size XS GN
Voltage waveforms with neutral conductor ("NAC"): Connect the device to a
type F fault-current circuit breaker (RCD type F).
Voltage waveforms without neutral conductor ("AC"): Connect the device to a
type B fault-current circuit breaker (RCD type B).
Notes on floor devices
The maximum output impedance on the grid connection point is 0.09 Ω.
n
The cross-sections of the connection cables are based on the power con-
n
sumption and local regulations.
Notes on UltraVent/UltraVent Plus condensation hood
For devices with a condensation hood, disconnect both device from the power
supply before servicing.
Before disconnecting the power cord from the power supply or reconnecting
the device, make sure that the device is switched off to prevent the condensa-
tion hood from starting up.
Notes on XS GN devices with a UltraVent/UltraVent Plus condensation hood
The condensation hood must be connected to a standardized power supply
n
network in accordance with the applicable regulations (VDE and UL/
CSA NEC regulations).
The condensation hood is connected to the power supply via a fixed con-
n
nection. The fixed connection must be accessible on-site with an all-pole
disconnecting device with a contact distance of at least 3 mm [1/8 inch].
If the condensation hood is connected with a power cable, the power cable
n
must always be accessible.
The condensation hood must be fused with a maximum of 15 A on-site.
n
The condensation hood is equipped with an approx. 2 m [approx. 6
n
1/2 inch] connection cable without a plug.
If the connection cable is replaced, use at least one cable of quality H05 RN-
n
F 3x1.5 mm
or by technicians authorized and trained by the manufacturer.
Before unplugging the power cord or reconnecting to the power supply,
n
make sure that the device is switched off to prevent the condensation hood
from starting up.
