Safety Notes
Review the drawings and illustrations contained in this guide before
proceeding. If there are any questions regarding the safe installation
or operation of the system, contact Alpha Technologies or the nearest
Alpha representative. Save this document for future reference.
To reduce the risk of injury or death, and to ensure the continued safe
operation of this product, the following symbols have been placed
throughout this manual. Where these symbols appear, use extra care
and attention.
The use of ATTENTION indicates specifi c regulatory/code
requirements that may affect the placement of equipment and /or
installation procedures.
ATTENTION:
Always verify proper polarity of cables before connecting the batteries
to the power module. The batteries are clearly marked for polarity. If
the cables become interchanged at the batteries the battery breaker
will trip.
In order to accommodate the high-inrush currents normally associated
with the start-up of ferroresonant transformers (400A, no-trip,
fi rst-half cycle), either a “high-magnetic” or an HACR (Heating,
Air Conditioning, Refrigeration) trip breaker must be used. Do not
replace these breakers with a conventional service entrance breaker.
Alpha recommends ONLY Square D breakers because of increased
reliability in this powering application. High-magnetic Square D circuit
breakers and a BBX option (UL Listed service entrance) are available
from Alpha Technologies.
Connecting to the utility should be performed only by qualifi ed service
personnel and in compliance with local electrical codes. Connection to
utility power must be approved by the local utility before installing the
power supply.
ATTENTION:
UL and NEC require that a service disconnect switch (UL listed) be
provided by the installer and be connected between the power source
and the Alpha power supply. Connection to the power supply must
include an appropriate service entrance weather head.
