Using The Correct Diode When Using The Customer Communication Module In Multiple Engine Applications{1902,0374}
Usage:
3500B EUI Engines;
3500 With EUI Option Engines;
EMCP II, EMCP II+, EMCP II+P GenSets
Reference: Owner's Manual, SEBU6874-03; "Customer Communication Module (CCM)".
The above referenced owners manual under section "Wiring Connections And Battery Power" advises that a diode must be used in multiple engine applications to prevent power-sharing between units. The proper diode to be used is a 5N-4988 Diode Assembly which is a 5 Amp, 600 Volt PRV diode. This diode assembly has an operating temperature of -40°C to 85°C (-40.0°F to 185.0°F).
