Figure 5-41 Option 3 for achieving IP54 (NEMA 12) through panel mounting
The heatsink fan installed on the Unidrive SPMC/U is IP21 rated as
standard. To achieve IP54 rating (NEMA 12) at the rear of the heatsink
for through panel mounting, the SPMC/U heatsink fan must be changed
for the IP54 version, part number 3251-7824.
The procedures in section 5.9
Heatsink fan operation
on page 54 should
be followed to change the fan.
If the standard fan is used in a dirty/dusty environment, reduced fan
lifetime will result. Regular cleaning of the fan and heatsink is
recommended in this environment. The heatsink fan installed in Unidrive
SPMA and SPMD are IP54 rated as standard.
The guidelines in Table 5-8 should be followed.
Table 5-8 Environment considerations
N
When designing an IP54 (NEMA 12) enclosure (Figure 5-39),
consideration should be given to the dissipation from the front of the
drive.

panel mounted
5.11 External EMC filter
In order to provide our customers with a degree of flexibility, external EMC
filters have been sourced from two manufacturers: Schaffner & Epcos.
Filter details for each drive rating are provided in the tables below. Both
the Schaffner and Epcos filters meet the same specifications.
Table 5-10 Single drive EMC filter details
The external EMC filters for Unidrive SPMA and SPMD are designed to
be mounted above the drive, as shown in Figure 5-42.
Mount the external EMC filter following the guidelines in section
6.13.5
Compliance with generic emission standards
on page 84.
