Supplying Power to NDTRELAY2

To supply power to the NDTRELAY2, plug the AC power cord into the unit’s Line Voltage Receptacle (see following

figure, lower image). Plug the other end of the cable into a suitable AC power outlet. Acceptable power is that which is in

the range of 85 VAC to 265 VAC, at 47 Hz to 440 Hz.

NDTRELAY2’s internal power supply converts the line voltage to +12 VDC. The DC power is made available to external

components through the DIN5 Power Out connector, located next to the Power Switch. You can power a ZonicBook from

this connector via a CA-115, DIN5 male to DIN5 male Power Cable. Note that an LED, located next to the Power Switch,

will light when the NDTRELAY2 is powered On (see following figure, lower image).
