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.
3.2.25 Using 115V supply voltage
Supplying the MAC800/1200 with 115 VAC, it can run with the same performance as
when supplied with 230 VAC – provided you solder the jumper as shown in the drawing.
Then the internal bus voltage will remain at the nominal value of 325 VDC even though
115 VAC is applied.
It is possible to supply the MAC800/1200 with 115 VAC without using the jumper, but
then the MAC800/1200 will only be able to operate within a limited speed range and the
motor efficiency and dynamic response will also not be optimal.
Therefore it is recommended to use 115 VAC with the jumper is soldered correctly.
To check that the jumper is set properly, the bus voltage displayed in the MacTalk main
screen must show approximately 325 VDC. If the jumper is not set correctly, the voltage
shown will only be half of this value (160-170 VDC).
Important!:
Make sure that the jumper is not short-circuited if 230VAC is applied since this will cause
fatal damage to internal components.
The MAC800/1200 motor is configured by default for 230VAC supply (jumper not short-
circuited) on delivery.
3.2.26 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.
