Chemical Hazards

Any gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery contain dilute sulfuric
acid, which is harmful to the skin and eyes. Emissions are electrolytic, and are electrically conductive and
corrosive.

To avoid injury:

• Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel

knowledgeable of batteries and the required safety precautions.

• Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove

all metallic objects from hands and neck.

• Batteries produce explosive gases. Keep all open fl ames and sparks away from batteries.

• Use tools with insulated handles, do not rest any tools on top of batteries.

• Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects

or other reproductive harm. Battery post terminals and related accessories contain lead and lead
compounds. Wash hands after handling (California Proposition 65).

• Wear protective clothing (insulated gloves, eye protection, etc.) whenever installing, maintaining,

servicing, or replacing batteries.

• If any battery emission contacts the skin, wash immediately and thoroughly with water. Follow your

company’s approved chemical exposure procedures.

• Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with

a solution of one pound Bicarbonate of soda to one gallon of water. Report chemical spill using your
company’s spill reporting structure and seek medical attention if necessary.

• All battery compartments must have adequate ventilation to prevent an accumulation of potentially

dangerous gas.

• Prior to handling the batteries, touch a grounded metal object to dissipate any static charge that may have

developed on your body.

• Never use uninsulated tools or other conductive materials when installing, maintaining, servicing or

2.3 Connecting Utility Power

WARNING!

ONLY qualifi ed personal should connect the utility power. Power must be connected in
compliance with local electrical codes, and common safety practices must be observed.

ATTENTION:

• Connection to utility power may need to be approved by the local utility before installing the
enclosure.

• Your local authority may require that a service disconnect switch (UL listed) be provided by the
installer and be connected between the power source and the enclosure.

WARNING!

Low impedance grounding is mandatory for personnel safety and critical for the proper
operation of the cable system .

Strike (Lightning) Ground

Lightning strikes, grid switching, or other aberrations on the power line and/or communications cable have the
potential to cause high-energy transients which can damage the powering or communitations systems. Without a low­impedance path to ground, the current, when traveling through wires of varying impedance, produce damaging high
voltage. The most viable method available to protect the system from damage is to divert these unwanted high-energy
transients along a low-impedance path to ground. A low-impedance path to ground prevents these currents from
reaching high voltage levels and posing a threat to equipment. The single-point grounding system provides a low­impedance path to ground, and the key to its success is the proper bonding of the ground rods, so the components of
the grounding system appear as a single point of uniform impedance. Alpha recommends the use of a surge arresting
device electrically bonded to the grounding system.

NOTE:

All ground rod connections must be made by means of a listed grounding clamp suitable for direct burial or
exothermically welded.

2.4 Enclosure Cooling

NOTE:

Consultation with Alpha Applications Engineering is required. Provisions must be made for adequate air
fl ow in the cabinet, equipment total heat dissipation load inside the cabinet, equipment min/max operating
temperatures, equipment over-temp fail safe shutdown capability, environmental outdoor design conditions,
and battery back up run times.

• Cooling capacity 200W dissipated with 10ºC rise over ambient.

• Two 100 CFM fans with variable speed temperature control.

• Fans are off below 25ºC. Fans increase from 40% to 100% with increased enclosure temperature
from 25ºC to 45ºC. Power to the Fan Control PCBA must be provided by a circuit breaker or fuse. 5A
recommended; 10A maximum.

• Form C dry contact alarm, fan fail, open on alarm.

• Maximum power draw 23W.

2.5 Cabinet Air Filtration

The system has an electrostatic fi lter that should be inspected for cleaning or replacement every six
months depending on time of year or environment. Clean the fi lters by back fl ushing with water in the
direction indicated and reinstall the fi lter with air fl ow direction pointing into the enclosure and drain
holes at the bottom.

NOTE:

Some environments may require more frequent inspections to maintain optimum airfl ow.
