The control wiring must be connected to the utility side of the line reactor
and is phase sensitive.
DANGER!
The AC control wiring to the 150A, 225A, and 300A units is phase sensitive.
If the AC control wiring is not in phase with power wiring catastrophic
damage to equipment will result.

The DC bus input may be connected to the DC bus of a single AC drive
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.
DANGER!
Never attach the DC bus input of the M3645P 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.

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.
