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
power supply terminals and AWG22 (cross section: 0.326 mm
2
section: 1.039 mm
) for other 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, power plugs etc.)
(12) The G3ZA is for single-phase loads only. Connect only single-phase zero-cross
SSRs.
Do not connect three-phase SSRs, magnetic relays, or SSRs that do not have
zero-cross function.
