WARNING
HAZARDOUS VOLTAGES
Insulation from channel to channel: Normally a channel can be safely connected to a
hazardous voltage up to 300V AC common mode* with respect to earth. However,
where a channel is connected to a safety low voltage circuit, an immediately adjacent
channel must be adequately insulated from hazardous voltages between 150V AC
and 300V AC max. This insulation should comprise of at least 1.5mm air gap, or a bar-
rier rated greater than 1400V AC. This is to ensure that protection of the safety low
voltage circuit is fully maintained.
*Common Mode” voltage is a voltage applied between the whole channel and earth,
not between pins on a channel. 300V AC is permitted at Measurement Category CAT
ll (Overvoltage Category ll)
Failure to comply with these instructions could result in death or serious injury.
