11 Spare and Optional Parts

11.1 Spare Parts

Table 17 lists the order numbers for the logic board and cooling fan(s) plus the quantity required for each soft starter.
11.1.1 Soft Starter Amps, U
Three ratings identify each soft starter: current in amps (In Line or Inside Delta), control supply voltage U
115 V AC, 230 V AC) and main supply voltage U
more of the ratings, e.g., each cooling fan corresponds to the Amps and U
= All, where All means either main voltage selection).

11.1.2 Fan Orientation

Between one and three cooling fans are used per soft starter depending on the ratings. When one fan is used, it is
mounted centrally along the width of the unit. When two fans are used, one is mounted to the left (L) and the other
to the right (R). Left and right are defined by facing the cover of the unit, consequently, the fan on the left is the
furthest from the control terminals. Similarly, when three fans are used, mounting locations are left (L), center (Ctr),
and right (R).
