NOTE: This output is not isolated. Isolation between
the instrument output and the power supply is
accomplished by an external solid state relay.

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).
NOTES:
1) For supply connections use 16 AWG or larger wires
rated for at least 75
°
C.
2) Use copper conductors only.
3) 24 Vdc supplies are not polarity sensitive.
4) The power supply input is
not fuse protected. Please
provide fusing as shown:

When the fuse is damaged the instrument should be
returned to your supplier to check the power supply.
