shown in figure 4.2.1 (these are also Terminal #s 21 and 22). This
control voltage must be customer supplied, unless an optional control
power transformer (see table below) has been supplied with the unit.

.2.1.a
When sizing a control power transformer for the TE...-BP Series
starter use the above chart for minimum sizes or supply capacity.
Any additional control devices powered by the same CPT must be
added to the above figures to ensure proper operation of the
Bypass Contactor.
NOTE:
TE-210 and larger units are available without the Bypass Contactor,
but fans are still included. CPT can be sized for fan loads only if
used in NEMA 1 ventilated enclosures.
4.2.1.b
Output relays in TB2 must be protected from currents in excess of
5A, either with a fuse or with other suitable current protection
devices.
A dedicated fault output for use in PLC or interposing relay control
is available on TB1. This opto-isolated Triac switch is rated for
50mA max., 10-250V AC/DC. Any circuit connected to it must be
fused accordingly.
