Kohler 26RCA Installation Manual page 54

Automatic paralleling requires:
1. Two single-phase generator sets as described above.
2. APM RDC2.4 paralleling firmware for the blue-board controller on each generator set. Download the latest version of
paralleling firmware from the Service Support section of the Kohler Power Resource Center (KPRC).
3. One Model RXT automatic transfer switch (ATS).
4. One Automatic Paralleling Module (APM) kit.
5. A personal computer (laptop) with Kohler
6. A load management device is required if one generator set cannot support the maximum total load.
The load management device (load shed kit or RXT combined interface/ load management board) is necessary in order to shed
non-critical loads in the event that one generator set shuts down and the other generator set cannot support all of the loads.
See TT-1596, provided with the APM, for complete installation instructions. The APM and associated equipment must be
®
installed by a Kohler trained and authorized dealer.
If the APM is not installed within sight of the generator sets, local codes may require the installation of circuit breakers near the
APM. Circuit breaker kits are available for installation inside the APM enclosure. See TT-1596 for the circuit breaker kit numbers.
