Power Circuit Terminals
Wire Size #14 AWG
-
#8 AWG
Wire with copper conductors only, unless terminals are
marked “AL-CU”
(Wire with conductors rated 75
°C
. If conductors rated
higher than 75
°C
are used, their size must be based on
the ampacity values for 75
°C
conductors. Terminal
torque values are shown in Table 2.)
Installation - Be sure power is off
The nameplate ratings of the contactor must agree with the
power supply and the rating of the load. Contactor mounting
should be solid to prevent vibration. When the contactor is
provided with a channel iron base, grout the base in place.
The preferred and recommended mounting position of the con
-
tactor is in a vertical plane. Before making any connections,
be certain that all leads to be handled are de-energized. With
power off, operate contactors, relays and interlocks to see that
they work freely. See that all terminals and current carrying
connections are clean and tight. For electrical connection, wire
per one of the schematics shown in Fig. 2 thru 4 depending on
the desired control.
(Magnetically-latched contactors are equipped with coils
designed for intermittent duty only. Faulty coil action can
be caused by a defective coil or damaged control module.
Replacement of both is recommended when the contactor
will not pull in or drop out. Coil replacement for the purpose of
changing the control voltage rating does not require auxiliary
contact or control module replacement.)
