Pre-installation Checklist
To Ensure Operator Safety:
• Only qualifi ed personnel should install the power supply in accordance with
all applicable electrical codes.
• Use eye protection whenever working with batteries.
• Use only sealed, lead-acid type batteries with a minimum rating of 55Ah
(gelled-electrolyte or equivalent).
Unpacking and Inspection:
• Remove the GMX Power Supply from the shipping container. Verify that
the power supply (including Remote Temperature Sensor) and any other
ordered options have been included.
• Carefully inspect the contents of the shipping container. If any items are
damaged or missing, contact Alpha Technologies or the shipping company
immediately. Most shipping companies only have a short claim period.
Preinstallation Inspection:
• During shipping, movement of components may occur. Inspect the power
supply for possible shipping-related failures, such as loosened or damaged
connectors. If needed, inspect the interior for loose or damaged connectors.
Correct any discrepancies before proceeding with the power supply
installation.
• Do not install the power supply without performing a complete
preinstallation inspection and start-up test.
Overview
Alpha GMX Uninterruptible Power Supplies are designed to power signal
processing equipment in cable television and broadband LAN distribution
systems.
During AC line operation, AC power is converted into a quasi square wave
and regulated by a ferroresonant transformer at the selected output voltage.
The regulated voltage is connected to the load via V
OUT ± terminal block
connections, and some power is directed to the battery charger to maintain a
fl oat charge on the batteries.
When the incoming AC line voltage signifi cantly deviates from normal, the
GMX Power Supply automatically switches from the AC line to Standby mode,
maintaining power to the load.
Key components include:
• Line Interactive Ferro Technology (LIFT)
• Wide input voltage range of ±30%
• Compact packaging with light-weight ferro
• Field programmable fl ash memory
• Built-in battery circuit breaker
• IEC style line cord
