1. Important Safety Instructions
This AVR has been designed to provide all the necessary safety conditions needed to protect electronic office
equipment including information systems. In case of any questions, refer to your authorized technical service
representative.
--
In order to avoid any damage to the equipment, it is advised to transport it in its own packing.
-- In the event of sudden temperature changes such as from cold to the normal working temperature, mist can
form inside the AVR. It is absolutely essential that the AVR be dry before switching it on. Due to this reason wait
for at least 2 hours before operating it.
-- Once it’s dry, make sure you observe all the conditions in the environment section of the technical
specifications table, before introducing it into the circuit.
Earth cable should be chosen concerning the current capacity. All units’ earth
connections, which are connected to AVR, should be done with this earth cable. Without
earth connection or unproved earth connected units are dangerous for user health and
have high risk of electronic circuit board faults. When installing the AVR to use cable with
improper diameter can be dangerous for user’s health and safety of the unit.
-- Place all the cables in a proper place so that they are not stepped on or get caught into people’s feet. Before
connecting the AVR to the circuit makes sure you carefully read all the instructions and warnings in the
“Installation” section of this manual.
--Don’t drop any foreign materials (like clips, nails etc...) into the equip- ment.
-- In emergencies (damage to the cabinet, front panel, or mains connections, splashing of liquid dropping of any
foreign materials into the equipment) switch-off the AVR, pull out the plug and inform the authorized service
center.
-- Do not connect any loads to the AVR, which exceed its power range.
-- When input distortion or resistance is too high, AVR may not work properly.
--Keep the packing for maintenance or moving.
-- Wiring must be tight, to prevent falling off and oxidation.
The AVR can only be repaired by the authorized technical service personnel. Any attempt
to open and to repair by the user on his own could prove to be dangerous.
Intended for installation in a controlled environment.
a. The controlled environment should accord with the requirement of the specification.
b. Do not install or operate your AVR in or near water.
c. Do not place AVR on an unstable cart, stand or table.
d. Do not place AVR under direct sunlight or close to heat emitting sources.
e. Do not place AVR power cord in any area where it may get damaged by heavy objects.
Placing magnetic storage media on top of the AVR may result in data corruption.
Special precautions:
When the AVR input comes from a generator:
a. Output power capacity must be higher than the AVR rating, or the AVR and generator may not work properly;
b. Output frequency of generator must be in range of 45 to 65Hz, and wave form must be sine wave, otherwise
the AVR and generator may not work properly.
