Microtest TSB-67 - 568A Annex E - Manual (Page 6)

High Voltage Protection
The PentaScanner +/ PentaScanner / PentaScanner Cable Admin, 2-Way Injector+/2-Way
Injector and Super Injector+/Super Injector are designed to withstand input hazard voltage
conditions that arise from normal telephony applications such as 48 VDC at less than 80 ma or 24
VAC used to power many keysets. The unit detects when a voltage of greater than ±15 volts is
applied on the inputs and sounds a warning to alert the user to remove the hazard condition
immediately to prevent possible damage to the input circuits. Tests cannot be performed when
hazard conditions are detected on the inputs.
