SAFETY NOTES:
1) Do not run input wires with power cables.
2) Permanently connected equipment must include a
switch or circuit-breaker in the installation. Place it in
close proximity to the equipment and within easy
reach of the operator. Mark it as the disconnecting
device for the equipment.
A single switch or circuit-breaker can drive more than
one instrument.
3) To avoid shock and possible instrument damage,
connect power last.
4) Before connecting the power line, check that the
voltage is correct (see Model Number).
5) When the NEUTRAL line is present, connect it to
terminal 12
NOTES:
1) For supply connections use 16 AWG or larger wires
rated for at least 75 °C.
2) Use copper conductors only.
3) Before connecting the power line, check that the
voltage is correct.
4) Polarity does not matter for 24 Vdc wiring
The instrument power supply is not fuse protected.
Please provide a fuse T Type, 1 A, 250 V when fuse is
broken. It is advisable to verify the power supply circuit,
so that it is necessary to send the instrument back to
your supplier
