Installation notes
Installation (MDR60A0150/0370/0750 and MDR61B1600/2500)
4.1.2
Minimum clearance and mounting position
• Observe the minimum wire bending spaces in accordance with EN 61800-5-1.
• Only install the units
vertically
. You must not install them horizontally, tilted or upside
down.
• Ensure unobstructed cooling air supply and make sure that the units are not sub-
jected to heated air from nearby components.
• Observe the following clearances:
•
MDR60A0150/0370:
Above and below at least 100 mm (3.9 in).
•
MDR60A0750 and MDR61B1600/2500:
Above at least 100 mm (3.9 in). With
temperature-sensitive components such as contactors or fuses, at least 300 mm
(11.8 in).
• No clearance required on the side The units can be arranged directly next to one
another.
4.1.3
Separate cable ducts
• Route
power cables
and
electronics cables
in
separate cable ducts
.
4.1.4
Fuses and earth-leakage circuit breaker
• Install the
input fuses at the beginning of the supply system lead
after the supply
bus junction (observe the wiring diagram for basic unit, power section and brake).
• SEW-EURODRIVE recommends not to use earth-leakage circuit breakers in plants
with frequency inverters as an earth-leakage circuit breaker reduces the plant avail-
ability.
4.1.5
Polarity of the DC link connections
• You must observe the
correct polarity of the DC link connections.
False polarity
of the DC link connections will cause
irreparable damage to the connected units!
The DC link connection carries a high DC voltage (approximately 900 V). Twist the
DC link cables and only route them inside the control cabinet.
4.1.6
Connecting inverters to the MOVIDRIVE
®
MDR60A/61B regenerative power supply unit
• If you use cables to connect inverters to the regenerative power supply unit, you have
to connect the inverters in
star connection
. Make sure to consult the installation
notes in the operating instructions for the inverter.
WARNING
Wrong type of earth-leakage circuit breaker installed.
Severe or fatal injuries.
The unit can cause direct current in the protective earth. If you use an earth-leakage
circuit breaker (FI) for protection in the event of direct or indirect contact, you may only
connect a type B earth-leakage circuit breaker (FI) on the supply side of the device.
