SECTION 2 - INSTALLATION

Risk of Property Damage. Do not apply

power to the system before checking all

wiring connections. Short circuited or

improperly connected wires may result

in permanent damage to the equipment.

1. Connect a 1.29-1.02 mm (16-18 AWG) wire from

a reliable ground reference to the SC-EQ Gate-

way’s incoming power ground lug. Do not re-

move the existing wire that connects the ground

lug to the enclosure cover.

2. On 120 VAC applications, connect the Hot wire to

TB-BLK and the Neutral wire to TB-WHT. Con-

nect the ground wire to the ground lug.
On 240 VAC applications, connect the Hot wire to

TB-YEL and the Neutral wire to TB-WHT. Con-

nect the ground wire to the ground lug.

IMPORTANT:

Use copper conductors only. Make all

wiring connections in accordance with local, national,

and regional regulations. Do not exceed the SC-EQ

Gateway’s electrical ratings.
