Precautions for Safe Use
(1) Do not use the product in the following locations.
• Locations subject to direct radiant heat from heating equipment
• Locations where the product may come into contact with water or oil
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or
ammonia gas) are present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
(2) Use this product within the rated load and power supply.
(3) Ensure that the rated voltage is achieved no longer than 2 s after turning
the power ON.
(4) Use/store within the rated temperature and humidity ranges. Provide
forced-cooling if required.
(5) Minimum mounting distance of G3ZA is 10 mm.
When mounting the G3ZA near the SSRs, mount the G3ZA so as to not
interfere with the heat dissipation of the SSR.
(6) Use the specified size of insulated type crimp terminals (M3, width:
5.8 mm max.) for wiring and attach insulative sleeves. To connect bare
wires, use AWG22 (cross section: 0.326 mm
2
2.081 mm ) to wire the power supply terminals and AWG22 (cross
section: 0.326 mm
terminals.
(7) Be sure to confirm the correct terminal and polarity when wiring the
terminal block and connectors.
(8) Do not connect any conductors to unused terminals.
(9) In order to prevent inductive noise, wire the lines connected to the
product separately from power lines carrying high voltages or currents.
Do not wire in parallel with or in the same cable as power lines. Other
measures for reducing noise include running lines along separate ducts
and using shield lines.
(10) Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, solenoids, magnetic
coils or other equipment that have an inductance component).
Do not install the product near devices generating strong high-frequency
fields or surges. When using a noise filter, check the voltage and current
and install it as close to the product as possible.
(11) For a safety disconnection of the power-line in the application the
equipment shall be provided with disconnecting devices suitable for
isolation (e.g. circuit breakers IEC60947-2, power switches IEC60947-3,
and power plugs).
