Caution! Do not plug in the power cord until the following steps are completed.
1. The square knockout on the wiring chassis must be removed.
2. The Heyco bushing must be attached to the power cord as shown. Use pliers to
push both halves of the bushing together until they lock.
3. Put the wires through the knockout and push the bushing into the metal until it
locks into place. The word Heyco on the bushing faces up.
4. Put each wire into the supplied connector and tighten the screws. The wiring label
located on the chassis will show where to connect the wires.

This system can accommodate both a primary and secondary (for backup) auxiliary time synchronization input.
The following protocols cannot be used simultaneously: 59 minute sync, 58 minute 1-4 sync, National Time/
Rauland, Dukane Digital, Rauland Digital and once a day Pulse. An example of a configuration would be
SNTP being the primary input and 58 minute correction being a secondary input. Setting the primary source
to 59 minute sync and the secondary source to Dukane digital would be an incorrect configuration.
