5.1 Installation instructions
Connecting sup-
ply system leads • The rated voltage and frequency of MOVIMOT
®
must correspond to the data for the
power supply system (mains).
• Cable cross section: according to input current I
mains
for rated power (see Technical
Data).
• Permitted cable cross section of MOVIMOT
®
terminals (does not apply to field dis-
tributor)
• Use conductor end sleeves without insulating shrouds (DIN 46228 part 1, material
E-CU).
• Install line safety at the beginning of the power cable behind supply bus junction (see
the section "Connection of MOVIMOT
®
basic unit," F11/F12/F13). Use D, DO, NH or
circuit breakers. The fusible rating should be selected in accordance with the cable
cross section.
• Do not use a conventional earth-leakage circuit breaker as a protective device. Uni-
versal current-sensitive earth leakage circuit-breakers (tripping current 300 mA) are
permitted as a protective device. During normal operation of MOVIMOT
®
, earth-leak-
age currents of > 3.5 mA can occur.
• Use contactor switch contacts to switch MOVIMOT
®
from utilization category AC-3
according to IEC 158.
• SEW recommends using earth-leakage monitors with pulse-code measurement for
voltage supply systems with non-grounded star point (IT nets). The use of such de-
vices avoids mis-tripping of the earth-leakage monitor due to the earth capacitance
of the inverter.
Installation at
1000 meters
above sea level
(msl) MOVIMOT
®
drives with supply voltages of 380 to 500 V can be used at altitudes above
2000 m MSL up to 4000 m MSL under the following peripheral conditions.
1)
• The rated continuous power is reduced based on the reduced cooling above 1000 m
(see the section "Technical Data and Dimension Drawings").
• Above 2000 msl, the air and creeping distances are only sufficient for overvoltage
class 2. If the installation requires overvoltage class 3, an additional external over-
voltage protection must be used to ensure that overvoltage surges are limited to
2.5 kV phase-to-phase and phase-to-ground.
• If safe electrical separation is required, it must be implemented outside the device at
altitudes above 2000 m MSL (Safe Electrical Separation in accordance with
EN 50178).
• The permitted rated supply voltage of 3 x 500 V up to 2000 msl is reduced by 6 V for
every 100 m to a maximum of 3 x 380 V at 4000 msl.

1) The maximum altitude is limited by creeping distances and flameproof components such as electrolytic
capacitors.
