6) Connect only the recommended optional brake resistor between the terminals P - PR
(+ - PR). Keep terminals P-PR (+ - PR) of 0.1K or 0.2K open.
These terminals must not be shorted.
0.1K and 0.2K do not accept the brake resistor. Keep terminals P-PR (+ - PR) open.
Also, never short these terminals.
7) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes harmonic components, which
may interfere with the communication devices (such as AM radios) used near the
inverter. In this case, install the FR-BIF optional radio noise filter (for use in the input
side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
8) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF
option) in the output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be
damaged. If any of the above devices are installed, immediately remove them.
(When using the FR-BIF radio noise filter with a single-phase power supply, connect
it to the input side of the inverter after isolating the T phase securely.)
9) When rewiring after operation, make sure that the POWER lamp has gone off, and
when more than 10 minutes has elapsed after power-off, check with a meter etc.
that the voltage is zero. After that, start rewiring work. For some time after power-off,
there is a dangerous voltage in the capacitor.
