Chapter 5 Main Circuit TerminalsMS300 (High Speed Model)
5-3
Terminals for connecting DC reactor, external brake resistor and DC
circuit
These are the terminals for connecting the DC-reactor to improve the power
factor and harmonics. At delivery they are shorted by a jumper. Please
remove it before connecting the DC reactor.
The jumper must be fastened tight when it does not connect DC reactor, use
DC+/+1, +2/B1 to execute common DC bus, or connect with brake resistor,
otherwise the drive might lose power or the terminals will be broken.
DC reactor optional ( )
DC+
Connect a brake resistor in applications with frequent deceleration, short
deceleration time, too low braking torque or requiring increased braking
torque.
Brake resistor
(optional)
+
The external brake resistor should connect to the terminals [+2 / B1], [B2] of
AC motor drives.
DO NOT short circuit or connect a brake resistor directly to DC+/+1 and
DC-, +2/B1 to DC- otherwise the drive will be damaged.
DC+ and DC- are to be connected in common DC bus applications, please
refer to Chapter 5-1(Main Circuit Terminal) for the wiring terminal
specification and the wire gauge information.
Remove the front cover
The front cover shall be removed before connecting the main circuit terminals and control circuit
terminals. Removing the cover acc. to the figure below.
The figure below shows Frame B model for example. Removing the cover on other frame sizes is
similar.
Press the clip on both sides, and take out the front cover by rotating.
