Precautions for Safe Use

(1) Use and store the Digital Controller within the specified ambient temperature and humidity ranges.
If necessary, cool the Digital Controller.
(2) Do not prevent heat dissipation by obstructing the periphery of the Digital Controller. Do not block
the vents on the Digital Controller unit.
(3) The supplied power voltage and load must be within the rated and specified ranges.
(4) Be sure to confirm the name and polarity for each terminal before wiring the terminal block and
connectors.
(5) Do not connect anything to unused terminals.
(6) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) to wire the terminal block.
(7) To connect bare wires to the terminal block, use AWG22 to AWG14 for the power supply terminals
and AWG28 to AWG16 for other terminals. (Length of exposed wire: 6 to 8 mm)
(Remove the sheath to expose 6 to 8 mm of the end of the wire.)
(8) Ensure that the rated voltage is attained within 2 seconds after turning on the power.
(9) If you need to draw out the Digital Controller, turn off the power first. Never touch the terminals or
the electronic components, or subject them to physical shock. When inserting the Digital Controller,
do not allow the electronic components to contact the case.
(10) Do not remove the inner circuit board.
(11) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
(12) Allow a warm-up time of at least 30 minutes.
(13) Install the Digital Controller as far away as possible from devices that emit strong, high-frequency
energy or devices that cause surges. Do not tie noise filter input/output wires together.
(14) Keep the Digital Controller wiring separate from high-voltage, high-current power lines. Avoid
connecting in parallel with a power line or on the same line as a power line.
(15) Install a switch or circuit breaker that allows the operator to immediately turn off the power, and
label suitably.
(16) Do not use in the following locations:
Locations where dust or corrosive gas is present (in particular, sulfur or ammonia gases)
Locations where condensation or ice may form
Locations directly exposed to sunlight
Locations subject to strong shocks or vibration
Locations where water or oil may splatter on the Digital Controller
Locations directly exposed to radiant heat from heating equipment
Locations subject to sudden or extreme changes of temperature
(17) Cleaning: Do not use thinners. Use commercially available alcohol.
(18) Use the specified cables for the communications lines and stay within the specified DeviceNet
communications distances. Refer to the User's Manual (Cat. No. H124) for details on
communications distance specifications and cables.
(19) Do not pull the DeviceNet communications cables with excessive force or bend them past their
natural bending radius.
(20) Do not connect or remove connectors while the DeviceNet power is being supplied. Doing so will
cause product failure or malfunction.

Conformity to Safety Standards
As shown in the diagram, each functional block
of the E5AR/ER is electrically insulated. <inputs>,
<event inputs/voltage outputs/current outputs>,
and <communication> are functional insulation
each other.
<inputs/ event inputs/ voltage outputs/ current
outputs/ communication> <relay output/
transistor output> are reinforced insulation each
other.
However, there are some exceptions.
