If your system requires output of UPS has N-G voltage close to 0Vac we suggest to install an isolation transformer at the UPS output.
Neutral line of secondary of the transformer can be connected to Ground (See FIG 3).
FIG-3
INSTALATION:
Install this unit in any protected environment with a dust free air flow. Also corrosive vapours and conductive contaminants must be
avoided. Do not use UPS outdoors or where either temperature or humidity exceeds tech specs. Install UPS at least 10 inches away from
your monitor to avoid magnetic interference.
1.- Plug input AC power cord to an appropriate power outlet with Line-Neutral-Ground contacts.
•
Some models come with input power-cord with appropriate plug for your country.
•
3KVA in 120V could come with input terminal block. For 3KVA-120V models input cable to be connected to input Terminal
Block must be AWG12 or wider (for lengths shorter than 50 feet – 15m). Wire size is strongly affected by length and
temperature. Input wire must be selected and installed by qualified personnel according to local regulations.
2.- First time leave UPS recharging batteries during 6 hours before connecting your devices to the UPS to let batteries recover charging
level to offer full battery backup time.
3.- Connect your devices to be protected to UPS outlets. Take care to not overload UPS output by connecting devices with higher power
ratings than UPS power capacity. Laser printers, scanners and copiers frequently have two different power ratings: in stand-by power
ratings are very low compared with consumption rating during operation. If this kind of products will be connected to the UPS operation
power rating must be considering to size total power consumption to be connected to UPS.
4.- EPO Function: Emergency Power Off function allows to power off UPS outlets when EPO input is open. When EPO port is closed EPO
function is disable. When EPO function is activated UPS will perform following actions:
a) Power Off all outlets,
b) Switch to STAND-BY mode,
c) Acoustic alarm is activated as continuous beep
d) Warning message Nº 20 is indicated on LCD.
To disable EPO mode and recovering normal mode contact switch or jumper in EPO port must be closed and UPS must be powered On
by selecting ON push button.
