●Mounting
• When mounting more than two Relays
side by side, keep a 3 mm gap
horizontally and vertically between
Relays to ensure a good heat
dissipation. It may cause a malfunction
if heat is not dissipated smoothly from
the Relay.
●Terminals
• The terminals fit FASTON receptacle
250 and are suitable for positive-lock
mounting. Use only Faston terminals
with the specified numbers.
Select leads for connecting Faston
receptacles with wire diameters that
are within the allowable range for the
load current.
Do not apply excessive force to the
terminals when mounting or
dismounting the Faston receptacle.
Insert and remove terminals carefully
one at a time. Do not insert terminals
at an angle, or insert/remove multiple
terminals at the same time.
Refer to the following table for
recommendations of connectors made
by OMRON.
●Other Precautions
• This Relay is suitable for power load
switching of air-conditioning
compressors and power supplies, etc.
Do not use the G4A to switch micro
loads less than 100 mA, such as in
signal applications.
