3.2 Utility Powering
• The XM2 Power Supplies are powered by either 120VAC or 240VAC (120/120 grounded neutral) attached to
an internal service entrance. The size of the service conductors must be based upon the actual size of the
utility service, and must comply with applicable electrical code requirements.
• Proper grounding is critical. A qualified electrician should verify that grounding complies with applicable
electrical codes. All applicable codes must be adhered to when installing a system, pouring concrete, or
placing a preformed pad. Local codes supersede any procedures outlined in this document.
• The following should be performed only by qualified service personnel and in compliance with local electrical
codes. Verify electrical codes prior to installation. Codes may vary and contain specific conduit and wire
sizes for connection to the service entrance. Connection to utility power must be approved by the local utility
before installing the power supply.
• All mounting hardware should be stainless or galvanized, depending on local environmental
conditions. Use of improper hardware may cause corrosion not covered under warranty.
• Soil conditions vary and may affect the integrity of the pad. Alpha Technologies recommends that
proper steps be taken to ensure that the soil supporting the pad is stable. Improper installation of
the pad may cause uneven settling or cracking not covered under warranty.
