6.8 Electrical Connections
6.8.1 Accessory Electrical Connections
Some accessories, including a run relay and a common
fault relay, can be connected to the generator set.
Contact an authorized service distributor/dealer for a list
of accessories.
Have the accessories installed by an authorized
distributor/dealer or a licensed electrician. Follow the
installation instructions provided with each kit. Most
accessories operate on 12 volts DC; some may require
AC line voltage. Use separate conduit for AC and DC
leads to reduce the possibility of electrical interference.
Verify that the leads and conduit do not interfere with the
operation of the generator set or obstruct the service
areas. Verify that the electrical installation complies with
the National Electrical Code (NEC) and all applicable
local and state codes. See Section 5, Wiring Diagrams,
for more information regarding generator set electrical
connections.
