D-100 Flow Display Manual 10/14 - 0634-14 / 18340 Page 21

3.3.9 Input Power

The D-100 can be ordered from the factory with input voltages of 24VAC 50/60Hz,

120 VAC 50/60 Hz or 240 VAC 50 Hz. Please note that these are not eld selectable

options. Conrm that the correct input voltage conguration has been provided prior to

making any connections.

WARNING

Conduit openings in the D-100 enclosure must be closed with UL listed ttings applicable to

NEMA 13 enclosures, and mains voltage connections must be made through the pre-drilled

conduit/strain relief opening located at the bottom of the enclosure. Failure to do so will result

in an increased risk of injury.

WARNING / CAUTION

The protective earth connection must be made as shown. Failure to do so will result in an

increased risk of injury and erratic operation.

Connect the power source to the D-100 through the conduit opening located on the

bottom of the enclosure. Attach the wires to the appropriate screw terminals as shown.

Connect the protective earth wire to the earth lug shown. Do not exceed 13 in-lb (1.5 Nm)

of torque when tightening.

As power is initially applied to the D-100, immediately conrm that the “power” light

is illuminated and the display is scrolling throught the character diagnostic test. The

test will begin by indicating the letter P in every position followed by a countdown from

9 to 0 for each digit. If this does not occur, disconnect power immediately and re-verify all

wiring connections. Contact ONICON if the problem persists.

Operating from 120 or 240 VAC mains power

Utilize an electrically clean power line, free of electrical noise and protected from high

voltage spikes, power surges, and brownouts. The power source should be a separate line

with its own circuit protection device. Refer to Section 1.3 of this manual for the

appropriate overcurrent device ratings. Use a 3-wire service in which one wire is a

protective earth ground.
