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 and M3324 have resettable fuses to match the required 24V
power supply.
DIP Switch / Fuse Location
*Indicates factory setting.
** DIP switches 1and 2affact the M3200LTR only.
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.
