GS4000 Installation Guide Revision 4.00
•
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.
•
Do not allow a heavy object to be placed on a power cable, since it could crush it.
Similarly, don't pull, bend, or otherwise mutilate the power cable, since this could cause
a fire or an electric shock.
•
There will be a maximum of 3.5 mA of leakage current with the GR4000-80E1, GS4000-
80E1, GR4000-160E1, and GS4000-160E1 and a maximum of 6 mA of leakage current
with the GR4000-320E (AC) and GS4000-320E (AC). When connecting the device to the
AC power supply, use only grounded power outlets. Failing to use grounded outlets
creates a shock hazard. Furthermore, you could introduce unwanted electrical noise
into the device, which could degrade performance.
Since a substantial amount of leakage current flows in the GR4000-320E (AC), be
careful when handling it and comply with the instructions in the label below:
•
If the power cable is ever damaged so that the wires underneath the covering are visible
or cut, stop using it and ask a maintenance person to replace it. Using damaged cables
could easily cause a fire or an electric shock.
•
Do not use adapters to connect multiple power cables to the same outlet. Doing this can
cause a fire or cause a circuit breaker to trip due to an overloaded circuit.
•
This device may have multiple power supplies installed, each having a separate source
of mains power. When turning power OFF to the device, make sure that all the power
switches and circuit breakers attached to the device are set to OFF. Comply with the
instructions written on the label attached to the device:
