■ Safety Precautions
*1 A SELV circuit is one separated from the power supply with double insulation or reinforced insulation, that
does not exceed 30 V r.m.s. and 42.4 V peak or 60 VDC.
*2 A class 2 power supply is one tested and certified by UL as having the current and voltage of the
secondary output restricted to specific levels.
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to electric
shock.
Do not allow pieces of metal, wire clippings, or fine metallic shav-
ings or filings from installation to enter the product. Doing so may
occasionally result in electric shock, fire, or malfunction.
Do not use the product where subject to flammable or explosive
gas. Otherwise, minor injury from explosion may occasionally
occur.
Never disassemble, modify, or repair the product or touch any of
the internal parts. Minor electric shock, fire, or malfunction may
occasionally occur.
CAUTION - Risk of Fire and Electric Shock
a) This product is UL listed as Open Type Process Control Equip-
ment. It must be mounted in an enclosure that does not allow
fire to escape externally.
b) More than one disconnect switch may be required to de-
energize the equipment before servicing the product.
c) Signal inputs are SELV, limited energy.*1
d) Caution: To reduce the risk of fire or electric shock, do not inter-
connect the outputs of different Class 2circuits.*2
If the output relays are used past their life expectancy, contact
fusing or burning may occasionally occur.
Always consider the application conditions and use the output
relays within their rated load and electrical life expectancy. The life
expectancy of output relays varies considerably with the output
load and switching conditions.
CAUTION
