WARNING
Fix the equipment. Do not put any object on PBX and Main Power; it might be danger-
ous if the object should fall down.
When plugging off a plug, be sure to grip the plug and extract it. If you grip the code
and extract it, it might cause a fire and an electric shock.
If a fault is considered as the lightening cause, ask the supplier.
Other than fulfilling the appropriate humidity and temperature, it is necessary to consid-
er the maintenance operation and the all-time ventilation in non-loading operation dur-
ing day-off and night. For example, when the height above floor is 1 m (3.281 feet), the
temperature should be from 20 to 25 °C (68 to 77 °F ) and the humidity should be more
or less 50 %.
