z Do not open the chassis while the switch is in operation. Do
not open the chassis if not necessary, even when the
switch is not powered on.
Installation Environment Requirements
The S1526 can be installed in a corridor or a room. The
following requirements must be met wherever it is installed in a rack
or on a workbench.
z There is adequate space (more than 10 cm (0.33 in.)) near
the ventilation hole of the switch for heat dissipation of the
switch.
z The rack or the workbench has an effective cooling
system.
z The rack or the workbench is sturdy enough to hold the
switch and its accessories.
z The rack or the workbench is well grounded.
Electromagnetic Environment Requirements
In operation the switch may be affected by external
interferences in the form of radiation or conduction. Make sure that:
z The AC power supply unit is a TN system and the AC
power socket uses a three-terminal, single-phase power
socket with Protection Earth (PE), so that the interference
from the power supply system can be effectively filtered by
the filter circuit in the device.
z The switch is kept far away from high-power radio
launchers, radar launchers, and any equipment with
high-frequency and high-current.
