GS4000 Quick Start Guide, Revision 3
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:
Do not block the ventilation slots. If you block the ventilation slots, the inside of the device will
overheat and could cause a fire. Reserve at least 70 mm of space from the ventilation slots of
each device to ensure proper air flow through the ventilation slots.
As shown in the drawings below, the ventilation slots are on the front, back, right, and left
sides for the GR4000-80E1, GR4000-160E1, GS4000-80E1 and GS4000-160E1, and they are
on the right and left sides of the GR4000-80E2, GR4000-160E2, GR4000-320E (AC), GR4000-
320E (DC), GS4000-80E2, GS4000-160E2, GS4000-320E (AC), and GS4000-320E (DC).
