Slave to Slave Interconnect
A second slave fan/heater unit can be added to op-
erate in unison with the master fan/heater unit and
another slave fan/heater unit. This would create a
three fan unit. The interconnect between the first
slave fan/heater unit and the second slave fan/heater
unit remains the same regardless of the type or pres-
ence of a control center. To wire a second slave fan/
heater unit to another slave fan/heater unit do the
following:

ELECTRICAL POWER SUPPLY
NOTE: Do NOT use solid wire for inter-
connection.
1. Run four (4) 16ga MTW type wires
from the first slave fan/heater unit to
the second slave fan/heater unit.
2. Connect the wires as shown in figure
#27.
NOTE: A shielded 16 gauge cable is recommended
for use on the network connections. The network
connections for this configuration are attached to
terminals number 7 and 8 in slave #1 and terminals
number 3 and 4 in slave #2. Ground each end of
the shielded cable to the housing. A shielded 16
gauge 2 wire cable can be purchased from GSI.
