Novus 1250T and P1250 UPS Safety Checklist
Only qualified personnel should service the UPS.
Carefully unpack the UPS and report any shipping damage at once.
Read this operator’s manual. If you have any questions about safe
installation,operationormaintenance,contactAlphaTechnologies.
Install the UPS upright in a well ventilated area.
Verify the UPS’s output voltage meets the voltage and current
requirements of the equipment to be protected. Do the same for the
line voltage and current input into the UPS.
The UPS should be installed on a dedicated, circuit breaker
equippedline.
Alert fire, emergency and service personnel a UPS is installed by
placing a warning label on the electrical panel and the host equip-
ment.
When connecting a load, make sure it does not draw more power
than the UPS provides.
Use proper lifting techniques when lifting the UPS (weight is 75 lbs,
34kg).
The UPS has more than one live circuit. Even if line power is not
present at the input, power can be present at the output.

Battery Compartment Safety Checklist
DANGER: The batteries are a shock risk. Observe these precau-
tions:
NOTE: The UPS is not turned off by turning the Battery Circuit
BreakerOFF.
Never let the front enclosure touch the battery terminals. A lethal
shock can result.
Before battery servicing remove all rings, watches and other
jewellery.
Use insulated tools when servicing the batteries or the UPS. Do not
lay tools on top of the batteries.
Do not let live battery wires touch the UPS’s chassis. Shorted
wires can cause a fire or explosion.
Wear insulated gloves and eye protection when servicing the
batteries.
Switch the battery circuit breaker OFF before connecting or discon-
nectingthe batteries.
DANGER:Lead–acidbatteriesgenerateHydrogengas,apotential
fire hazard. The following precautions must be followed:
Do not smoke, use fire or create sparks near them.
Touch a grounded metal surface before servicing the batteries to
discharge any static electricity.

1.3 ATour of the Alpha P1250 and 1250T
Purpose: Describes various features of the P1250 and
1250T UPS's .
NOTE: This UPS is available in P1250 and 1250T models. Most of the
information in this manual applies to both and it is called the “UPS.”
Where there are specific instructions for a particular model, the model
name is used.
1.3.1 Enclosure (Figure 1.1)
The electronics and batteries are protected from the weather by a two–piece type 3R
metal enclosure. To access the interior, unlock, lift up the front enclosure and move
it out of the way. A nylon rope and a grounding wire connecting the two halves are at
the bottom.
A lock at the bottom of the front enclosure prevents unauthorized personnel from
opening it. The keys are shipped in the mounting kit.
DANGER: When mounting the front enclosure onto the rear, take great care
that the front does not touch the battery terminals. A lethal shock can result.
