10 Spare and Optional Parts

10.1 Spare Parts

Table 10 lists the catalog numbers for the logic board, cooling
fan(s), snubber board(s) and power modules plus the quantity
required for each controller.
10.1.1 Controller Amps, Uc and Ue
Three ratings identify each controller: current (Amps - In Line or
Inside Delta), control supply voltage Uc (24V DC, 120V AC, 230V
AC) and main supply voltage Ue (200-400V AC, 230-575V AC).
Each spare part relates to one or more of the ratings, e.g., each
cooling fan corresponds to the Amps and Uc ratings regardless
of the Ue ratings (Ue = All, where All means either main voltage
selection), whereas, each snubber board corresponds to the
Amps Amps

Amps and Ue ratings regardless of the Uc ratings (Uc = All,
where All means any of the three control power choices).
10.1.2 Fan Orientation
From one to three cooling fans are used per controller depend-
ing 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).
