3. INSTALLATION
Unpacking: Before unpacking your unit, examine the shipping carton for damage. If there is any
obvious damage, report it immediately to the dealer or carrier. If no damage is found, unpack the unit
and inspect it for shipping damage. Again, in case of any damage, report it directly to the dealer or the
carrier.
Environment: The MESTA UPS is designed to be used in an environment with a temperature range of
0-40°C and relative humidity of 0-95%, without condensation. The site should not be excessively dusty
or dirty. Clearances should be provided to the front and back of the unit so as not to block air inlets
and outlets. Also, keep the top of the unit clear of objects. The unit should never be used to sit or
stand on.
Location of Unit: The UPS should be in close proximity to the protected equipment: the longer the AC
wire runs, the more voltage drop and more risk of noise getting back into the system there are.
Voltage/Power Rating: Make sure that the voltage and power rating match the available line voltage
and load requirements. This can be done by comparing the input and output information printed on the
rating plate of the UPS with your requirements.
Power Cord Plug-in: Having verified voltage and power ratings, you are now ready to plug the UPS
into the AC power. Your unit will either have a detachable power cord or one that is fixed to the UPS.
(If you have a detachable cord, it was shipped with the unit. Only use this cord with your UPS. Do not
substitute other cords in its place as their current ratings may not be sufficient for your UPS needs.
Plug the detachable cord into the UPS input receptacle.) Now plug the AC power cord into the utility
receptacle at your facility.
UPS Power On: Having plugged your UPS into the AC utility, you may now turn on your UPS using
the front panel power switch. After a few seconds delay, the UPS will begin operating. Initially (for a
very short period of time) all front panel lights will flash on simultaneously, and the audible alarm will
beep once. Then the UPS will "power up" with the "UPS" red front panel light on. If the AC power
utility is present and within tolerance of the UPS, the "AC LINE" green front panel light will also be on.
After and additional couple of seconds, the "UPS" red light should go off, and the "AC LINE" green light
should remain on, indicating that the UPS is able to derive power from the AC power utility.
Fault Checking: If the normal UPS Power On sequence does not occur for you, perform one of the
following alternative actions:
1) If the "UPS" red light comes on and remains solidly on (also eventually to be accompanied by
an audible beeping alarm), recheck your connections to the AC utility. (Also check to see if any
breakers or fuses in that particular circuit of your building or in the back of your UPS are open.)
If after rechecking no problem is found, and the UPS will not perform according to the proper
procedure described above, contact the factory for further assistance.
2) If the normal UPS Power On procedure is not observed, and the warning conditions described
in alternative #1 are also not observed, contact the factory for further assistance.
Connecting the Load: Assuming that normal operation was observed, you can now plug your loads
into the receptacles at the back of the UPS. If during this procedure the "OVERLOAD" red light comes
on or starts blinking along with an audible alarm, your load is too large for the UPS, and some must be
removed or the UPS will shut down.
Installation Complete: Assuming an overload doesn't occur prior to attaching and turning on all loads,
you have completed the installation procedure of your UPS. From here on there is no special powering
up or powering down sequence that needs to be followed for either your load equipment or the UPS.
This installation procedure is only necessary to insure that the UPS did not incur any internal shipping
damage and that your building's AC utility is getting to the UPS.
