Getting Maximum Battery Life From the
Pulsar Eclipse Plus 250 

1.

Prior to first use, charge the Pulsar
Eclipse Plus 250 battery for 8 hours.
This helps condition the battery for long
life.

2.

After a complete discharge, a few hours
are required to reach full recharge.

Notes:

1. Pulsar Eclipse Plus 250 is equipped with a
12V/4.2Ah lead acid battery, which must be
disposed of in accordance with local
regulations. MGE will accept UPS and/or
batteries for recycling free of charge. Contact
us at the phone number shown in the
recycling section of this manual.

2. Battery life is cut in half for every 15
degrees above 75°F. Plug in and recharge the
UPS at least every six months if the UPS is
taken out of service and not plugged in.

ID Labels and Cable Organizers

Eclipse Plus 250 includes ID labels to label
each item plugged into the UPS. Simply peel
off the label which matches the device you
have plugged in (or type the name on the
blank labels) and attach it to the recess next
to the outlets. Attach the matching label to
the cord of the device. In this way, you can
always return each device to its proper
location should you need to remove it.

The cable organizers are provided to “clean
up" the installation. Locate the cable
organizer where it will restrain the cables to
the UPS in  optimum locations. Clean the
location where the organizer will be mounted
to remove any traces of oil or dirt. Remove
the covering on the self-adhesive backing.
Press into position and allow to set overnight
for adhesion to properly set. Be sure to
attach organizer when temperatures are
above 70°F. Press cables into organizer and
close cover.

Battery Replacement

before removing batteries. This  must be done
by knowledgeable personnel due to risk of
electric shock and high energy.
