Connect the leads of the high-duty brake resistor to the P and PR
terminals of the inverter. When using the 15K inverter, connect two
high-duty brake resistors (18
Ω
) in parallel. When using the H15K
inverter, connect two high-duty brake resistors (18
Ω
) in series using the
terminal block enclosed.
•
If the resistor lead length is not sufficient to reach the inverter terminals,
additional lead wire, sized as noted below and not exceeding 5 m in
length, may be used. Installation shall be in accordance with the North
American or Canadian Electrical Code.
4. INSTRUCTIONS FOR USE
•
Setting of inverter parameters
1) The parameter setting method varies with the inverter series.
Refer to the instruction manual of the inverter.
CAUTION
1. The high-duty brake resistor cannot be used with a brake
unit, high power factor converter, power return converter,
built-in brake etc.
2. Twist the leads of the high-duty brake resistor when increas-
ing their length 2m or more. (The wire size used should be
minimum 14 AWG (2.1mm
2
)).
Note that even the twisted leads cannot be made longer than
5m. Doing so can cause an inverter failure.
3. The FR-ABR-(H)11K, 15K can not be used with the FR-A500
series.
