GS4000 Quick Start Guide, Revision 3
Do not use a power source or voltage that exceeds the specifications of the GR4000 or GS4000.
Observe the instructions on the device chassis.
The current capacity of a distribution panel must be greater than that of the operating current
fed to the circuit breaker. If not, the circuit breaker may not work properly when a circuit
abnormality is detected. This condition could cause a fire.
Because DC power cables are connected using screw terminals instead of plugs, attaching or
removing a DC power cable to or from the device must be done by a trained maintenance
person. Mishandling DC power cables can cause a fire or an electric shock.
Make sure that the circuit breaker of a power facility is set to OFF before attaching or removing
a DC power cable. Attaching or removing a DC power cable with the circuit breaker set to ON
will cause an electric shock.
When replacing a power supply or installing an additional one, remove the power cable from
the power supply to be replaced. Even if the power switch is turned OFF, electricity is still
present in the cables connected to the device, which can cause a fire or an electric shock.
When using a DC power cable, attach an insulating sheath at the 0v and -48V/-60V cable
terminal. Using an unsheathed DC power cable could cause an electric shock.
After attaching a power cable, attach the cover to the terminal plate when using DC power
supply. Otherwise one of the power supply terminals could short out or you could receive a
shock.
Installing or replacing an optional module, such as a Network Interface (NIF), the installation
must be done by a trained maintenance person.
When connecting the device to the DC power supply, use the EARTH (GROUND) terminal to
avoid an electric shock or the trouble related to electric noises.
To measure the voltage at the GS4000-80E2, GS4000-160E2,
GS4000-320E (AC), and GS4000-320E (DC), the end
terminals are attached to these devices. To avoid a fire or an
electric shock, do not insert small pins or paper clips into the
terminal.
To measure the voltage at the GS4000-80E2, GS4000-160E2,
GS4000-320E (AC) and GS4000-320E (DC), the end terminals
are attached to these devices. Measuring the voltage should
be done only by engineers or qualified maintenance personnel.
