WARNING
HAZARDOUS VOLTAGES
Insulation from channel to channel: Normally a channe l can be sa fely conn ected 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 bar­rier 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 M easurement Category CAT ll (Overvoltage Category ll)
Failure to comply with these instructions could result in death or serious injury.

WARNING
HAZARDOUS VOLTAGES
Insulation from channel to channel: Normally a channel can be safely connected to a hazardous voltage up to 150V AC common mode* with respect to earth. However, where a channel is connected to a safety low voltage circuit (i.e. is accessible for op­erators to touch), any channel within the same 'input bank' must be limited at all time s to a maximum of 55Vac or 140Vdc**. This is to ensure that protection of the safety low voltage circuit is fully maintained.
The inputs are divided into two banks: inputs 1 to 3 are one bank, and inputs 4 to 6 (if fitted) are another bank. A voltage of up to 150V AC common mod e can be applied on one bank as long as any safety low voltage circuits are on the other bank. The recorder is protected against accidental connection of a voltage up to 240V AC common mo de which might occur as a temporary fault condition, provided there are no safety low volt­age circuits connected to the same input bank as the channel with the fault.
*Common Mode voltage is a voltage applied between the whole channel and earth, not between pins on a channel.
** this reduces to 33Vrms or 70Vdc if any channel within the input bank is configured as an ohms or R/T measurement.
Failure to comply with these instructions could result in death or serious injury.
20 43-TV-25-30 Iss.6 GLO Aug 07 UK
CAUTION
CONTROL UNIT DAMAGE
Do not apply a hazardous live voltage between + and - pins within a channel (e.g . 60V maximum on voltage ranges, 5V maximum on millivolts ranges).
The * pin should be connected only as part of ohms or R/T me asurements. Ohm s and R/T measurements share a common connection (* pin) with all channels in the same bank (the inputs are divided into two banks: inputs 1 to 3 are one bank, and inputs 4 to 6, if fitted, are another bank). To avoid damage, ensure t hat a channel selected as ohms or R/T remains floating, i.e. the sensor is not connected to any external voltage.
Alternatively, if an ohms or R/T sensor must be biased to an external voltage, ensure that the other two channels within the same input bank a re floating or are biased to the same voltage (i.e. - inputs of all three channels connected to the same voltage).
Failure to comply with these instructions may result in product damage
