2) Sound Isolation Pads and Vibration Isolation Kits
For maximum absorption of vibration and reductions of sound
levels, additional sound isolation pads are recommended for
installation between the transformer and the mounting surface.
These molded neoprene and steel plate assemblies
virtually eliminate vibration noise between the transformer and
the mounting surface.
Consult the HPS standard products catalog, general
information section, for the part number of the correct
isolation pad required.
3) Connectors (Lugs)
Connectors for the installation of dry-type transformers
are readily available. These connectors are suitable for use with
either copper or aluminum cables.
Connectors should be sized, installed and connected
to cables in accordance with your local electrical code
requirements using the best practices to ensure safe and
reliable operation. Cable surfaces should be properly cleaned
and electrical compound should be used for all connections.
Selecting Connectors
a) Determine the primary current for the required
transformer from the Appendix A.
b) Similarly, determine the secondary current rating for the
transformer from Appendix A.
c) For 120/240 voltage connections the current should be
based on 120 volts.
d) For 240/480 volt connections, the current should be
based on 240 volts.
