4.2.1 AC Control Power Supply Connection
Separate AC Control Power supply is required to power the electronics
of the
TE Series
starter. 120VAC is standard; order 240VAC (optional) if
necessary for your line power supply configuration. The control voltage
must be connected to terminals marked A1 and A2 of TB-2 as shown in
figure 4.2.1 (these are also Terminal No.’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.
4.2.1.a
Control Power Requirements
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 values to ensure proper operation of the Bypass
Contactor.
4.2.1.b
Control Fusing
The output relay contacts(TB2) must be protected from currents in
excess of 5A by either using fuses or 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., 10-250VAC. Any circuit connected to it must be fused
accordingly.
