2.5.7 Optional Load Control Connection
Connector P11 on the interface module provides a
connection point for optional load control circuits. The
load control contact provides a delayed contact closure
to allow startup of selected loads 5 minutes after transfer
to the emergency power source (generator set). Use
this contact to delay startup of equipment with large
motor-starting loads such as air conditioners.
See Figure 2-11 for the location of load control
connector P11. See Figure 2-12 for contact ratings,
connection, and wire size information.
Note: An optional load control module is available for
generator sets equipped with the RDC2 or DC2
controller.
The load control module allows
management of up to six separate loads (two
HVAC thermostat connections and four other
non-essential loads). See TT-1574, Load Control
Module Instructions.
