When external brake resistance is needed,
disconnect B1、B2[Note 2], and the external
brake resistance is bonded to P、B1, so that B2
is suspended.

When using external braking resistor, must
first be open between P and B in braking
resistance line, at the same time the two
braking resistor inside thread on NC, then the
external braking resistor jumper on the P、B.

Note 1. GL1A0, GL240, GH260, GH320, GH390 have no internal brake resistor: GL1A0 generally does not
need to connect the brake resistor; However, when GL240 needs to connect the external brake resistor,
the external brake resistor should be straddled at the P and B ends, and the NC is suspended; GH260,
GH320, GH390 braking resistor in P and B side directly.
Note 2. It is the default internal brake resistance connection when delivered: B1 and B2 are short-connected, N1
and N2 are short-connected.
