Mitsubishi Electric GOT1000 General Description Manual page 24

*1 When mounting an extension unit on the upper stage of
MELSECNET/H communication unit (GT15-J71LP23-25, GT15-
J71BR13) or CC-Link communication unit (GT15-J61BT13), the
operating ambient temperature must be reduced 5°C against the
maximum values described in general specifications.
*2 When using the MELSECNET/10 communication unit (GT15-
75J71LP23-Z, GT15-75J71BR13-Z) or CC-Link communication unit
(GT15-75J61BT13-Z), refer to the manual of the communication unit
you use. (Differs with the specification of GOT.)
*3 Do not use or store the GOT under pressure higher than the
atmospheric pressure of altitude 0m (0ft.). Failure to observe this
instruction may cause a malfunction.
*4 This indicates the section of the power supply to which the
equipment is assumed to be connected between the public electrical
power distribution network and the machinery within the premises.
Category II applies to equipment for which electrical power is
supplied from fixed facilities.
The surge voltage withstand level for up to the raged voltage of 300 V
is 2500 V.
*5 This index indicates the degree to which conductive material is
generated in the environment where the equipment is used.
In pollution degree 2, only non-conductive pollution occurs but
temporary conductivity may be produced due to condensation.
*6 The wet-bulb temperature is 39°C or less for STN LCDs.
