3.3.1 Ramp Times Using Jumpers
Inverter ramp times are set using a series of 5 jumpers (fit jumper to enable
function). Each jumper must be set as shown in Table 3-1.
The jumpers overwrite the default settings or the ramp times specified using
BOP/AOP/IBN software.
The inverter recognizes when jumper values have been set when power is re-
applied.
CAUTION
Jumpers have priority in setting ramp times. When the jumpers are removed the
ramp times are not changed. It is then possible to change ramp times via the
parameters (using the BOP).
Ramp times apply to Ramp Up and Ramp Down. Jumper locations are as shown in
Figure 3-3.
Figure 3-3
Using up to 5 jumpers allows ramp times to be set between 1 - 240 s. Also see
Table 3-1.
