2.0 Installation
2.1 Mounting the LTI2 PRO
Interchangeable mounting brackets are provided for 19” rack mounting. When mounting the LTI2 PRO in any
configuration, consider the size and weight of the Inverter. The rack must be able to support the weight of the
inverter, as well as an additional safety factor. Refer to Table 1 to verify the weight of the inverter. The location
chosen for the inverter should be within an ambient temperature range of -4˚F to 122˚F (-20˚C to 50˚C) with a
non-condensing relative humidity no higher than 95%. The inverter should be mounted in an area free of explosive
materials and away from any liquids. Avoid using equipment in a location with corrosive gases (e.g. over flooded
Lead Acid batteries) and dust. The LTI2PRO utilizes fan-assisted cooling, so clearance of at least 6 inches of free
air must be maintained in front and on top for proper cooling. Maintain 12 inches (300 mm) or more of clearance
at the rear of the inverter when rack mounting to allow for operation and maintenance. The preferred fastener is
a machine bolt backed with a flat washer, lock washer, and nut. All hardware should be corrosion-resistant.

3.2 Start-Up Sequence
3.2.1 Commissioning
Check whether the DC input voltage is consistent with the nameplate label; in case of any inconsistency, please
do not apply the DC power supply to an inverter, in order not to cause any damage! Check whether the wiring
polarity of the DC input is correct; or else, the inverter cannot be normally started. Check whether the wiring of
AC input and output is correct and confirm that there is no short circuit phenomenon.
If there is no error in the above checks, respectively apply DC power supply and AC power supply. Turn-on the
startup switch to power-up the inverter. Firstly, all LEDs perform a lamp test for self-inspection. Then, the output
relay is closed to output AC power to the load.
3.2.2 Startup
Confirm whether DC input and AC output of the power supply is correctly and reliably connected. After the pressing
power switch to rightwards, the inverter performs self-inspection. Before steady output, the inverter power supply
checks the external environment and checks whether the inverter supply power itself is normal; if various status
parameters of the inverter power supply and the mains are normal, the inverter will steady operate in mains
status or inverter status (AC-dominated inverter is steady in mains output status and DC-dominated inverter is
steady in inverter output status). It takes about 5 seconds to complete the startup process.
3.2.3 Shutdown
After the pressing power switch to leftwards, the inverter LED indicator light and the inverter power supplies are
turned off.
3.2.4 Mute
In the case of the inverter power supply faults, the system will send audible and visual alarm which can be set
through LCD, to the mute audible sound of a particular alarm, select Turn Off in the sound control option.
The operator can directly press ENT (temporary) button to inactivate and activate an audible alarm. For the
same alarm, the muted alarm will not be automatically turned on; if there is another alarm, no matter whether
the last alarm is under mute status or not, the system will automatically turn on the audible alarm.
