Connecting The Device To Ac Power; Leveling The Weighing Platform - Minebea Intec Signum 3 Ex Operating Manual

Connecting the Device to AC Power

Before startup, make sure that the power cable is properly connected to the power supply�
!
In particular, the protective conductor must be connected to the housing of the adapter�
Connect all devices via their equipotential bonding conductor terminals to the equipotential
bonding conductor� Installation must be carried out properly by trained personnel and
according to commonly accepted technical standards�
The system should only be operated for the first time when it is certain that the area is not
!
potentially explosive� If deviations are evident during startup due to transport damage, the
system should be disconnected from the power supply and Service should be contacted
(no display, no backlighting despite weight value display, no reproducibility of the weight
value, no stability in the display, etc�)
YPS02-X�� Pressure-enclosed Adapter:
!
– Both cables should be laid fixed
– Flexible cabling with screws available upon request
Check the supply voltage/frequency and plug design�
!
– If they do not match: Contact your supplier
! Use only an original AC adapter:
– YPS02-Z�� or YPSC01-Z (for use outside of explosion-risk areas only)
– YPS02-X�� or YPSC01-X (for use inside explosion-risk areas)
When operating a scale in an explosive area:
!
– Follow all current standards and regulations for the installation of devices in the explosive
area�
– Device installation in Zone 1 should be carried out by trained personnel and checked
properly�
! Connect devices to a central equipotential bonding conductor before operation:
Warm-up Time
To deliver precise results, the scale must warm up for at least 30 minutes after initial
connection to the power supply� Only after this time will the scale have reached the required
operating temperature�
Using a verified scale in legal metrology:
Make sure to allow the analyzer to warm up for at least 24 hours after initial connection to the
$
power supply�

Leveling the Weighing Platform

Purpose:
– To compensate for unevenness at the place of installation
– To ensure that the equipment is placed in a perfectly horizontal position for consistently
reproducible weighing results
Always level the weighing platform again any time after it has been moved to a different
location�
Level the weighing platform using the four leveling feet� Turn the feet until the air bubble is
§
centered in the level indicator�
Check to ensure that all leveling feet rest securely on the work surface�
§
> Each of the leveling feet must support an equal load�
