Hitachi GR4000 Series Installation Manual page 13

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
leakage current with the GR4000-320E (AC) and GS4000-320E (AC). When
connecting the device to the AC power supply unit, 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 amound of leakage current flows in the GR4000-320E (AC), be
careful when handling it and comply with the instuctions in the label below:
Use the power cable packed with the device. Similarly, do not use the device's power
cable for the equipment other than the GR4000 or GS4000. In both cases, using an
improper cable could cause a fire or an electric shock.
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).
