Cautions for Grounding
- Do not connect the grounding wire of the OfficeServ 7400 system to a power
conduit of a building
- The standards for power and grounding should comply with the country standard
and the pertinent work should be conducted according to the country standard.
- External grounding is required to prevent personal injury or system damage
caused by lightning, static electricity, or voltage surge.
- Unplug the AC power cord before connecting the grounding wire. Failure to do
so may cause personal injury.
- The OfficeServ 7400 system should be connected to an outlet with a protective ground.
- The GND on the rear panel of the OfficeServ 7400 system should be grounded.
Caution for AC Power Connection
A single AC outlet should be used solely for the system’s AC power. Sharing the
AC power with other devices may cause noise or a voltage drop, resulting in a
system malfunction or fire.
Caution for C.O. line Connection
Do not connect C.O. lines in extreme weather conditions such as storms and light-
ning.
Voltage surges may cause system damage or personal injury.
Use of External Grounding
External grounding is required to prevent personal injury or system damage
caused by lightning, static electricity, or voltage surge.
