3.2
This solder jumper
must be shorted
if 115V is used as
supply voltage
Warnings:
Make always sure to switch
off power for 5 min. before
operating inside the motor.
Do not short-ciruit this
jumper if 230V is used
as supply voltage.
Internal damaged
will occur.
3.2.17 Using 115V supply voltage
When using 115VAC supply voltage, the MAC800 will be able to operate within a limited
speed range.
The motor efficiency and dynamic response will however not be optimal.
To optimise the performance it is recommended the internal jumper shown above is sol-
dered. By doing this the internal bus voltage will remain at the nominal value of 325VDC
when 115VAC is applied.
To check that the jumper is set properly, the bus voltage displayed in the MacTalk main
screen must show approximately 325VDC. If the jumper is not set correctly, the voltage
shown will only be half of this value (160-170VDC).
Important !:
Make sure that the jumper is not short-circuited if 230VAC is applied since this will cause
fatal damage to internal components.
The MAC800 motor is configured by default for 230VAC supply (jumper not short-
circuited) on delivery.
3.2.18 Prefuse when using 115V supply
To fulfil UL requirements, the prefuse must be a class RK5 such as the type FRN-R-15
(15Amp.) from manufacturer: Cooper Bussmann INC.
