When an adapter panel is not used, automatic shorting of CT inputs is not provided by the
TCC300/M-2050; the customer must provide a mehod for shorting the CT's before the control is disconnected.
1. Motor voltage may be 120 or 240 V to neutral, or 240 phase to phase.
2. The customer is to provide an earth ground connection to the CT/VT's neutral connection, external to the control
3. To Motor Power Seal-in board.
4. If the TCC300 is configured for the SCAMP push button Auto/Manual Switch type, the Self-Test Alarm relay is NOT avai-
lable.
