3.4 Utility Powering
The XM2 Power Supplies are powered by either 120Vac or 240Vac (120/120
grounded neutral), attached to an external service entrance. The size of the
service conductors must be based upon the actual size of the utility service and
be in accordance with applicable electrical code requirements.
The utility conduit may be placed in two locations, depending upon the utility
service entrance requirements. Note the optional conduit location for use with
meter base and the standard location for entry directly to the load center.
Proper grounding is critical. The enclosure MUST have a hardwired ground to the
service entrance. A qualified electrician should verify that grounding is in
compliance with applicable electrical codes.
NOTE: All applicable codes must be adhered to when installing a system,
pouring concrete, or placing a preformed pad. These codes supersede
any procedures outlined in this document.
NOTE: All mounting hardware should be stainless or galvanized steel, depending
on local environmental conditions. Use of improper hardware may cause
corrosion which is not covered under warranty.
NOTE: 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 which is not covered under warranty.
CAUTION: 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.
