1.5. INSTALLATION
1.5.1. Previous Inspection
After having removed the equipment from its original packing material, check for
visible signs of damage which may have occurred during shipment. Report any
shortage or damage to the freight carrier and KROMA or its representative
inmediately.
Check that you have received the following accessories with the monitor:
•AC power cord, and
•User´s Manual.
If the equipment has to be reshipped to a long distance, it is recommended to use
the original packing material in order to avoid damages during transport.

1.5.2. Safety Information
For electric shock protection, it is necessary to connect the chassis to a protective
ground; to this purpose, the earth ground terminal of the plug is directly connected
to the metal part of the monitor (green-yellow wire). Insert the power plug in a
mating outlet with an earth ground contact.
Due to the presence of high voltages inside the equipment, the same can only be
open, adjusted or repaired by QUALIFIED PERSONNEL.
1.5.3. Connection to the Main
Before connecting the monitor to the mains, check that the mains voltage
corresponds to that indicated in the voltage selector located in the rear panel, next
to the mains connector.
If the mains voltage presetting is not the appropriate, carry out the change by
removing the fuseholder and turning it until the desired value is shown in the
window.
Fuses should be changed in accordance with the mains voltage presetting used, as
per the following table:
POWER FUSE
220 V 2.5 A Slow
110 V 3.15 A Slow
1.5.4. Location
Due to the CRT´s sensitivity to magnetic fields, avoid installing the monitor near this
type of disturbance sources such as: Loudspeakers, electric motors, transformers,
etc.
The monitor has a dagaussing device incorporated which operates automatically
when the equipment is switched on. It can also be activated manually from the front
panel controls.
If the monitor is changed of location, some colour impurities may occur due to the
variation of the earth magnetic field. This problem disappears by activating the
degaussing circuit with the DEG key.
During the time this operation last, avoid placing near the monitor items which have
magnetic information such as: tapes, cassettes, cards, etc.
1.5.5. Tally Lamp
This lamp, located on the monitor´s front panel, can be activated with voltages
within the range + 24V and + 48 V, or by closing of the contacts 2 and 3 of the
connector located in rear panel. (SEE FIGURE).

1.5.6. Ground Terminals
There are two ground terminals: protective ground and electrical earth or ground
from the power supply. They are normally connected by means of a metal jumper,
but they can be isolated one another by eliminating said jumper, in case it is
necessary to avoid hum pickups due to the installation.
1.5.7. Remote Control Connectors (RS-485 Interface)
They are located at the rear of the video unit. The connectors, in loop through
configuration, are prepared for connection of the KROMA RK-5400 remote
control.This connector, are also useful for to update the futures software versions
