2. Heater Connections
The heater output(s) utilizes either AMP Mate-’n’-
Lok® connector(s) or twist-and-lock connector(s).
The mating connector and terminals are provided.
To ensure proper crimping of the AMP Mate-’n’-Lok®
terminals, the proper equipment should be used.
AMP recommends using part number 90300-2 for
terminal crimping and part number 458994-2 for
extraction of the terminals from the connector.
Please consult the TYCO-AMP Corporation at 1-800-
468-2023 for further information.
3. Thermocouple Connections
Using a small screwdriver, remove the two screws
holding the cover of the male miniature thermocou-
ple connector(s). Loosen, but do not remove the +
and - terminal screws. The connector(s) can accom-
modate wire sizes up to 20-gauge, stranded wire.
Insert the red wire from the thermocouple to the (-)
terminal of the connector(s). Do not wrap the wire
around the terminal. Repeat the step for the positive
thermocouple lead.
