Electrical Installation
5.3.5
Definition PE, FE
•
PE
refers to the mains-side protective earth connection. The PE conductor in the
mains connection cable may only be connected with terminals marked with "PE"
(these are designed for the maximum permissible mains connection cross-section).
•
FE
refers to connections for "functional ground". You can connect any existing
grounding conductor in the 24 V connection cable.
WARNING
Electric shock due to incorrect connection of PE to the terminals marked
with "F" (functional ground). The FE connections are not designed for this purpose. This
means electrical safety is not guaranteed.
Severe or fatal injuries.
• Connect the PE conductor in the mains connection cable only to terminals marked
with "PE".
5.3.6
Installation altitude higher than 1000 m above sea level
MOVIFIT
®
FDC and the MOVIGEAR
®
and DRC drive units with supply voltages of 380
to 500 V can be used at altitudes above 1000 m asl up to a maximum of 4000 m asl
under the following circumstances:
• The rated continuous power is reduced based on the reduced cooling above 1000 m
(see "MOVIGEAR
®
" or "DRC" operating instructions).
• Above 2000 m above sea level, the air distances are only sufficient for overvoltage
class 2. If installed at altitudes higher than 2000 m above sea level, you have to install
additional external overvoltage protection to limit overvoltage peaks to 2.5 kV phase-
to-phase and phase-to-ground.
• If safe electrical disconnection is required, it must be implemented outside the device
at altitudes of more than 2000 m above sea level (safe electrical disconnection in ac-
cordance with EN 61800-5-1 and EN 60204-1).
• Up to 2000 m asl, the permitted nominal line voltage is 3 x 500 V. It is reduced by 6 V
every 100 m to a maximum of 3 x 380 V at 4000 m asl.
5.3.7
Plug connectors
All MOVIFIT
®
plug connectors are illustrated in these operating instructions with view on
the contact end.
5.3.8
Protection devices
• The connected MOVIGEAR
®
and DRC drive units are equipped with integrated pro-
tective overload devices, which means that external devices are no longer required.
• Line protection must be implemented up to MOVIFIT
®
FDC using external overload
devices.
• For line protection between MOVIFIT
®
FDC and the MOVIGEAR
®
and DRC drive
units from 2.5 mm
2
, you can use the ABB MS325 motor protection switch integrated
in MOVIFIT
®
FDC; factory set to 15 A for 2.5 mm
2
, 20 A for 4.0 mm
2
.
• Observe the relevant standards concerning cable cross section, voltage drop and in-
stallation type.
