UNPACKING
A charger is shipped attached to a wood skid. This facilitates handling with a lift truck by inserting the
forks under the bottom of the skid. A smaller unit is covered by a carton and banded to a skid. A larger
unit is bolted to a skid and covered by a shipping carton that is banded to the skid.
Export packaging consists of a crate, a moisture-resistant cover for the charger, and a drying agent. The
charger is bolted to the crate.
To unpack:
Do not stand in front of steel bands since they may
whip out when cut.
Ne pas se tenir devant les bandes d'acier, lorsque
coupées.
Cut the bands and remove carton from the skid.
1. Either remove the unit from the carton or unbolt the unit from the skid.
2. Check the shipping carton, before discarding, for the packing slip and other material, which may
be contained in it.
3. Carefully inspect the charger for shipping damage (i.e. loosened connections or mountings,
dislodged circuit boards). If damage is detected, notify UNIPOWER, LLC; contact information
is provided in Section 1.5 Product Support.
STORAGE
If the charger is not to be used immediately, store it (fully packed, if possible) in a clean, dry location
protected from physical damage, condensation, and overhead drip.

PRODUCT DESCRIPTION 1.1
The Micro ARE-M series of single-phase, controlled ferroresonant float chargers is intended for utility,
communications, and other applications where a source of stable, electrically clean, reliable DC power is
needed. Available models provide an output voltage of 24 VDC and an output current from 6-100
amperes, depending upon model. Refer the Model Designation for a list of standard models and options.
Installation is quick and easy. The design accommodates floor, wall, or rack mounting with standard and
optional brackets. A mounting method is usually specified on the equipment order so the proper brackets
can be supplied.
The charger is configured and operated from the front of the unit. The control section includes a 2-line
digital display, 4-button keypad, green AC on LED and a red alarm LED, an AC input circuit breaker, and
a DC output circuit breaker. An optional control board offers front panel LED indicators, showing the
status of the High Voltage Alarm, Low Voltage Alarm, No Charge Alarm and AC Fail Alarm on the
telecom models. For the utility models two additional LEDs show the state of the Positive and Negative
ground fault alarms.
Access to internal components for servicing by qualified personnel is through the door comprising the
front of the unit. The door is hinged on the left and secured on the right by two fasteners.

2.2.2 Selecting and Sizing DC Power Cables
Protective circuits, overall system performance, and safety depend on the proper sizing of DC cables for
ampere ranges and acceptable DC voltage drop. Read the electrical installation section before sizing the
DC cables.
Perform the following procedure to determine wire size.
1. Calculate the minimum circular mils (CM) required for copper wire using the following formula:
where:
CM = minimum area of circular mils in the cable
I = maximum current (in amps)
L = one-way cable length (in feet)
V = allowable loop voltage drop (in volts)
Example:
Assume a maximum output current of 25 amperes, an allowable loop voltage drop of 0.5 volts, and a
distance of 50 feet between the charger and the load.
I = 25 amperes
L = 50 feet
V = 0.5 volts
11. After calculating the minimum circular mils, select the proper copper wire size from Table 2-2;
always choosing the next larger wire size if the area rating falls between values. For the above
example, select 2 AWG (35 mm
2
) wire.
12. Determine the minimum wire size for ampacity according to the code authority having jurisdiction in
your location.
13. Select the larger of the sizes calculated for voltage drop or ampacity.
