1.2 General Warnings and Cautions
You must read and understand the following warnings before installing the Alpha Micro Secure and its components. Failure to do so could result in personal injury or death.
• Read and follow all instructions included in this manual.
• Do not work alone under hazardous conditions.
• Only qualified personnel are allowed to install, operate and service this system and its components.
• Use proper lifting techniques whenever handling equipment, parts, or batteries.
• Always assume electrical connections or conductors are live. Switch off all circuit breakers and double-
check connections with a voltmeter before performing installation or maintenance.
• Place warning label(s) on the utility panel to tell emergency personnel a UPS is installed.
• The Alpha Micro Secure uses more than one live circuit. AC power may be present at the outputs even if the
system is disconnected from line or battery power.
• The Alpha Micro Secure’s surface can be very hot to the touch.
• Battery installation and servicing should be done or supervised by personnel knowledgeable about batteries
and their safety procedures.
• If electrolyte splashes on your skin, immediately wash the affected area with water. If electrolyte gets into
your eyes, wash them for at least 10 minutes with clean running water or a special neutralizing eye wash
solution. Seek medical attention at once.
• Neutralize spilled electrolyte with special neutralizing solutions in a “spill kit” or a solution of 1 lb. (0.45 kg) of
baking soda (bicarbonate of soda) in 1 gallon (3.8 L) of water.
• Be extra cautious when connecting or adjusting battery cabling. An improperly connected battery cable or
an unconnected battery cable can result in arcing, fire, or explosion.
• Use new batteries when installing a new unit. Verify that all batteries are the same type with identical date
codes.
• Always replace batteries with ones of identical number, type and rating. Never install old or untested batteries. One sealed lead-acid battery is rated to a maximum voltage of 12Vdc.
• A battery that shows signs of cracking, leaking or swelling must be replaced immediately by authorized personnel using a battery of identical type and rating.
• Keep the chassis area clear and dust-free during and after installation.
• Keep tools away from walk areas where you or others could fall over them.
• Wear safety glasses when working under any conditions that might be hazardous to your eyes.
• Do not work on the unit or connect or disconnect cables during periods of lightning activity.
• Do not smoke or introduce sparks in the vicinity of a battery.
• Never open or damage the batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic
and hazardous to the environment.
• A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:
a. Remove watches, rings, or other metal objects.
b. Use tools with insulated handles.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect the charging source before connecting or disconnecting battery terminals.
f. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source from the
ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such
shock can be reduced if the grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
6
017-220-J0 Rev B
• Never let live battery wires touch the Alpha Micro Secure the enclosure or any other metal objects. This can
cause a fire or explosion.
• Never dispose of batteries in a fire. The batteries may explode. Follow the manufacturer’s directions and
check with your local jurisdictions for safe battery disposal.
• Before attaching the batteries to the Alpha Micro Secure make sure that the polarity is correct.
• If the batteries have been in storage for more than 3 months, recharge them for at least 24 hours and then
test them with a load before installation.
• Each AlphaCell™ battery has a date code, found on the warning label, which must be recorded in the maintenance log. If non-Alpha batteries are used, see the manufacturer’s documentation for date code type and
placement.
1.3 Certifications and Compliances
The Alpha Micro Secure has been designed, manufactured, and tested to the requirements of the following national and international safety standards:
Safety:UL 1774 ed4; CSA C22.2 107.3-05; EN 62040-1* (*applies to 230Vac units only)
EMC:FCC Part15, Subpart B Class A; ICES-003 Class A; EN 62040-2 Class A* (*applies to 230Vac
units only)
This equipment has been tested and found to comply with the limits for a Class A digital device
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.

3. Site Planning
WARNING!
The Alpha Micro Secure must be installed in a restricted area accessible only by quali-
ed service personnel.
The Alpha Micro Secure must be correctly grounded for proper operation according to
local and national electrical code.
The utility line attached to the Alpha Micro Secure input MUST be protected by a circuit
breaker certied for this use in accordance with the local electrical code.
The AC input and AC output must each have a disconnect device attached. This device
can be a listed branch circuit protection device or a disconnect switch used on AC Line
only. Neutral or ground must never be disconnected by the user except during installation or maintenance.
3.1 Safety Precautions
• Install the Alpha Micro Secure and batteries in a restricted access location, and on a structure that supports the total weight.
• The input wiring must reach a suitably grounded power outlet and the load wiring must reach the
Alpha Micro Secures output terminal blocks.
Observe the following EMC requirements when setting up the Alpha Micro Secure and its internal equipment:
• All AC mains and external supply conductors must be enclosed in a metal conduit or raceway when specified by local, national, and/or other applicable government codes and regulations.
• The customer facilities must provide suitable surge protection.

Follow these guidelines for unpacking the Alpha Micro Secure.
WARNING!
The Alpha Micro Secure is heavy, more than 45 kg (100 lb) with batteries. Use proper
lifting techniques. The lifting and moving should be done by at least two people to avoid
injury.
1. Select a suitable area for unpacking.
2. Store all the packing material and boxes for possible equipment returns.
3. Check the contents in your product package. See “Checking the Package Contents” on this page.
4. Compare the packing slip and the list of parts with the items you received. If the list of parts on your packing
slip does not match the items you received, or any items appear damaged, immediately notify your carrier
agent and the supplier who prepared your shipment.
4.2.1 Checking the Package Contents
Before starting the installation, inspect the package contents and make sure the following standard items as well
as purchased options are included.
Once the installation location has been planned and prepared, you are ready to install the Alpha Micro Secure.
There are three steps to setting up the Alpha Micro Secure:
1. Mounting the Alpha Micro Secure
2. Wiring the Alpha Micro Secure
3. Installing and wiring the external batteries
5.1 Transporting and Lifting
WARNING!
To avoid personal injury or damage to the equipment, always use at least two installation personnel to remove the unit from its container.
Batteries must not be installed until the Alpha Micro Secure enclosure has been securely set in place at its permanent location. Transporting the unit with batteries installed
may cause a short circuit, re, explosion, and/or damage to the battery pack, enclosure
and installed equipment. Damage caused by improper shipping or transporting a unit
with batteries installed is not covered by the warranty.
5.2 Mounting Options
Choose any of the following four mounting options:
• Mounting to a wall
• Mounting to a wooden pole
• Mounting to a steel/concrete pole
