Level the machine
Place level gauges as shown in the right figure.
●Level: 4 locations
Level the machine with the adjustment bolts.
●The bubble should stay centered or within
3 division. (0.06 mm/m)
●4 adjustment bolts
Secure the adjustment bolts with the lock nuts.
You are recommended to check the level every six months after installation.

■About PCB transfer height
●The standard PCB transfer height of NPM-TT2 is from 900 to 920 mm.
●If the PCB transfer heights of all your production-line NPM-TT2s cannot be 900 to 920 mm, please
consult our sales representative or customer service in advance.
●Depending on your plant floor conditions, the PCB transfer heights of your production-line machines
can vary as shown in the figure below, in which feeder carts may not be connected normally to
machines #2 and #15.

Maintenance
14-4-1
Ensure that the voltage setting of the machine is the same as that of the plant’s primary power supply.
●Before shipment, the voltage setting of the machine is configured as previously arranged with you.
Check the voltage indicated on the supply
voltage label

●Before using 290 V AC or
higher (any taps equal to or
higher than 380 V AC), ensure
that the voltage between a
ground and each phase is 290
V AC or lower and that star
connection is used on the
feeding side, with the N
(neutral) terminal connected to
the ground.
ATTENTION
●Before changing the primary input tap, make sure that the voltage after the tap change is the
same as the plant’s primary power-supply voltage. If not, the main transformer could generate
heat that causes the machine to malfunction.
●Separately use the breaker on the plant side. Before starting electrical construction, check the
specification for the rated power consumption and consult an electrical contractor. The shared
use of the breaker with other equipment may cause a fire due to heat generation.
●Even with the main power turned OFF, power is supplied up to the primary power line. Be careful
during maintenance work.
