Maintenance
To prevent electrical shock or equipment damage, unplug the PS-B unit’s power cord from the power
supply prior to installing or wiring the PS-B.
Do not use the voltage not specified in the manual. Doing so may cause a fire or an electric shock.
Do not connect or disconnect Host and PS-B unit communication cables while the PS-B is turned ON.
The PS-B uses a lithium battery for backing up its internal clock data and the battery may explode if it is
replaced incorrectly. When replacement is required, use a Pro-face-designated replacement product.
