Installing The DXP Plus
Expansion Common Equipment Cabinet
1.0 Installing The Expansion Common Equipment Cabinet
1.1
Considering The Mounting Parameters
Mount the first expansion cabinet above the main common equipment cabinet and mount the second expansion
cabinet below the main common equipment cabinet.
Insure that the expansion cabinet is within four feet of it own dedicated 117VAC, 15 AMP electrical outlet. (The
expansion cabinet requires its own dedicated 117VAC 15 AMP circuit, with a third-wire ground, supplied to a
standard NEMA 5-15R electrical outlet and supplied from the opposite phase of the AC power line that supplies
power to the main cabinet.)
CAUTION
This dedicated AC circuit must different from the dedicated AC circuit that you provide for the main
cabinet. For best results wire the expansion cabinet’s dedicated AC circuit from a power phase that is
opposite from the one that supplies the main cabinet’s AC circuit.
