Notor: 1.
2.
Connect the brake unit to the inverter so that
the terminals 01 the same symbols are un-
nected. II the brake unit is not connected wr-
redly,
the inverter may be damaged.
Wires mnectig
the inverter and the brake
unit and
those connecting Me discharge
capacitor and
the brake unit should be as
short as possible. If wire length exceeds 2m
(6.58 feet), use hvistebpair wire. The length
must not exceed 5m (16.40 feet) even if the
hvisted-pair wire is used.
rn Cautlonr on Handling
1. If the brake unit keeps operating beyond its rating, the thermal relay incorporated in the
brake unit
will trip. If the thermal relay is tripped, reset it and increase the deceleration time
of the inverter.
2. The discharge capacitor will be heated to 1OO'C (212'F). Use high temperature wire and
insure that
wires are not exposed.
Wires may get hot enough
to bum the skin.
