Operating Instructions – MOVIFIT
®
-FC
5.2.11 UL-compliant installation
• Use only copper conductors with a temperature range of 75°C as connection cables.
• MOVIFIT
®
-FC is designed for operation on voltage supply systems with a maximum
supply current of AC 5,000 A and a maximum rated voltage of AC 500 V.
• As unit fuses for MOVIFIT
®
-FC, use UL-compliant fuses whose performance data
does not exceed 25 A/600 V.
• Units in connection with ABOXes MTAxxx-M11-xx or MTAxxx-M12-xx have branch
circuit protection.
• For UL-compliant installation, only the EBOX specified on the ABOX nameplate may
be mounted to the ABOX. The UL certification refers only to the ABOX/EBOX com-
bination stated on the nameplate.
• For UL-compliant installation, the load capacity of the X1 power terminal is limited to
a maximum of 25 A (sum of the device current and the pass-through current to con-
nected devices).
• For UL-compliant installation, the maximum ambient temperature of the
"MTF1.A040-503-…" is limited to 35°C (with P
rated
reduction: 3% I
N
per K to max.
55°C)
5.2.12 Installation altitude higher than 1,000 m above sea level
MOVIFIT
®
with supply voltages of 380 to 500 V can be used at altitudes of more than
1,000 m (3,281 ft) above sea level up to a maximum of 4,000 m (13,123 ft) above sea
level under the following peripheral conditions:
• The rated continuous power is reduced based on the reduced cooling above 1,000 m
(see section "Technical Data").
• At 1,000 m (3,281 ft) above sea level and higher, the air and creeping distances are
only sufficient for overvoltage class 2. If the installation calls for overvoltage class 3,
you will 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 unit at
altitudes of more than 2,000 m (6,561 ft) above sea level (safe electrical disconnec-
tion in accordance with EN 61800-5-1 and EN 60204).
• Up to 2,000 m above sea level, the permitted rated supply voltage is 3 x 500 V. Every
100 m, it is reduced by 6 V to a maximum of 3 x 380 V at 4,000 m above sea level.
TIP
The UL certification only applies for operation on voltage supply systems with voltages
to ground of max. 300 V. UL approval does not apply for operation on voltage supply
systems with a non-grounded star point (IT systems).
