The AC control wiring to the M3645-x300T is phase sensitive. If the AC
control wiring is not in phase with power wiring catastrophic damage to
equipment will result.
3.4.1.3. DC BUS INPUT
The DC bus input may be connected to the DC bus of an AC drive, the
DC output of a diode sharing unit, or to a common DC bus. If a reactor
or choke are being used in the bus, make sure the actual connection is in
parallel with filter capacitors of the drive/inverter.
Never attach the DC bus input of the M3645 to braking terminals on the AC
drive, commonly marked “BR”. These terminals are intended for use with an
external resistor, and are not directly connected to the bus filter capacitors of
the drive. Damage may occur if these terminals are used.
Please refer to your AC drive manual or AC drive technical support department
for assistance with this connection.
3.4.1.4. GROUNDING
Using the ground stud provided, ground the chassis in accordance with
local codes. Typically, the wire gauge will be the same as is used to
ground the attached drive.
Table 3-2: Power Terminal Specifications - 30 Amp Unit – M10 Chassis
Table 3-3: Power Terminal Specifications - 50 Amp Unit – M11 Chassis
Table 3-4: Power Terminal Specifications - 100 Amp Unit – M12 Chassis
Note: All power wire should be selected to match or exceed the voltage rating of the unit.
Field wiring for terminals will be copper 75
°
C wire only.
