Wiring 4-13
The following are the designated reactors. These reactors are
integrated for three phases consisting of three single phase reactors.
When selected reactors are installed, set their capacity to the
parameter F.013.
Model 8720MC-LR14-070B (1200 micro-henry):
For Model 8720MC-RPS065BM and
8720MC-RPS065BS units that are used at 80 Amps or
less (capacity of applicable motor is 37 kW or less)
Model 8720MC-LR10-062B (1100 micro-henry):
For Model 8720MC-RPS065BM and
8720MC-RPS065BS units that are used at 60 Amps or
less (capacity of applicable motor is 30 kW or less).
Model 8720MC-LR05-048B (800 micro-henry):
For Model 8720MC-RPS065BM and
8720MC-RPS065BS units that are used at 48 Amps or
less (capacity of applicable motor is 22 kW or less).
Model 8720MC-LR03-032B (850 micro-henry):
For Model 8720MC-RPS027BM, 8720MC-RPS065BM
and 8720MC-RPS065BS units that are used at 32 Amps
or less (capacity of applicable motor is 15 kW or less).
The reactor should operate in an ambient temperature of 50 degree
C (122 degree F) or lower. If it is not avoidable to use a reactor
above 50 degree C (122 degree F) , decrease current 1% for every 1
degree C above 50 degree C.
Select temperature rating of wire to connect a reactor as follows.
For Model 8720MC-LR14-070B reactor used with current of
60 Amps or lower, and for Model 8720MC-LR10-062B,
8720MC-LR05-048B and 8720MC-LR03-032B reactors,
select a temperature rating 105 degree C (221 degree F) or
higher.
For Model 8720MC-LR14-070B reactor used with a current
between 60 and 80 Amps, select a temperature rating 130
degree C (266 degree F) or higher.
Be sure to provide required quantity of reactors for all units
connected in parallel (see Figure 4.2 or 4.3).
Installing Varistor
Install a varistor to absorb serge voltage between AC input power
wires. The following is the designated varistor.
For 8720MC-RPS027BM, 8720MC-RPS065BM and
8720MC-RPS065BS units: 8720MC-VA-B
Be sure to provide required quantity of varistors for all units
connected in parallel (see Figure 4.2 or 4.3). Also be sure to
connect the varistor on the incoming AC line side of the AC
contactor.
