• Where the power line contains voltage spikes, or near any equipment which generates
large electrical noises.
4. Do not plug the power box into the AC power outlet before you are sure that its voltage
requirement (as marked at the rear of the power box) matches your voltage supply.
If the voltage setting does not match your supply, follow the instructions in Chapter 6 for
changing the power box's voltage setting.
5. Do not connect voltage exceeding +24V to input terminals.
6. Never connect voltage from a power supply directly to any open collector outputs. The
open collector outputs must always be connected to a load. Never connect a load to any
