6.2.7
Plug connector
All MOVIFIT
®
plug connectors are illustrated in these operating instructions with a
contact end view.
6.2.8
Protection devices
MOVIFIT
®
drives are equipped with integrated overload protection devices, which make
external devices obsolete.
6.2.9
Installation at more than 1000 m (3,281 ft) above sea level
MOVIFIT
®
with supply voltages of 380 to 500 V can be used at altitudes of more than
1000 m (3,281 ft) above sea level up to a maximum of 4000 m (13,123 ft) above sea
level under the following peripheral conditions:
• The rated continuous power is reduced due to the reduced cooling above 1000 m
(3,281 ft) (see the section "Technical Data").
• Above 1000 m (3,281 ft) above sea level , the air and creeping distances are only
sufficient for overvoltage class 2. If the installation requires overvoltage class 3, you
must provide 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 (6,561 ft) above sea level (safe electrical discon-
nection in accordance with EN 61800-5-1 and EN 60204).
• Up to 2000 m (6,562 ft) above sea level, the permitted rated supply 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 (13,123 ft)
above sea level.
6.2.10 Wiring check
Before connecting the system to the power source for the first time, you must perform a
wiring check to prevent damage to persons, systems, and equipment caused by incor-
rect wiring:
• Remove all electronic units (EBOX) from the connection units (ABOX).
• Check the insulation of the wiring in accordance with applicable national standards.
• Check the grounding.
• Check the insulation between mains cable and DC 24 V cable.
• Check the insulation between mains cable and communication cable.
• Check the polarity of the DC 24 V cable.
• Check the polarity of the communication cable.
• Ensure equipotential bonding between the MOVIFIT
®
units.
After the
wiring check
• Install and fasten all electronics units (EBOX).
• Seal all cable glands and plug connections that are not in use.
