Precautions
Mounting
When mounting two or more relays side by side, provide a minimum space of 3 mm horizontally and vertically between relays to ensure a good
heat dissipation. Malfunction may occur if heat is not dissipated smoothly from the relay.
Terminal Connection
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 on 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 examples of positive-lock connectors made by AMP. Contact the manufacturer directly for details on connectors,
including availability.

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 microloads
less than 100 mA, such as in signal applications.
