Toshiba TE2 Series - AC Control Power Requirements

TE2 Series Digital Solid State Soft Starter User Manual 17 | Page
4.2.1 AC Control Power Supply Connection
Separate AC Control Power supply is required to power the electronics
of the TE2 Series starter. The standard is 120VAC, but 240VAC
(optional) can be ordered 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 TE2…-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., 10-250V AC. Any circuit connected to it must be fused
accordingly.
