DIP Switches
Fuses
The M3200, M3200LTR and M3300 ship from the factory with fuses NOT
installed. Install the appropriate supplied fuse to match the voltage being used.
The M3224 has a resettable fuse to match the required 24V power supply.
DIP Switch / Fuse Location
* Indicates factory setting.
** DIP switches 1 and 2 have no affect on M3200 and M3224.
This module must be set up for the actual supply voltage.
If power supply is 115V
Step 1 Set power selector in position 115V
Step 2 Mount fuse 80mA T
If power supply is 230V
Step 1 Set power selector in position 230V
Step 2 Mount fuse 50mA T
Note: Power selector and fuses are
found under cover on top of module.
Caution
Failure to follow instructions
may result in equipment
damage or personal injury.
