Safety Precautions
■
Precautions for Correct Use
Please observe the following precautions to prevent failure to
operate, malfunction, or undesirable effect on product performance.
Load Connection
Securely tighten the LOAD terminal screws with the torque specified
in the following list after you connect the load to the LOAD terminals.
If the tightening torque is not enough, the terminals will generate
heat.
Mounting
When you locate the G3NH near other equipment, take the heat
resistivity of the equipment into consideration. The temperature of
the G3NH’s heat sink will rise by approximately 50
°
C with a rated
current flow through the G3NH.
The G3NH will rise the ambient temperature. When mounting the
G3NH inside a panel, install a fan for proper ventilation.
When closely mounting the G3NH Solid State Relays side by side,
reduce the load current 30% lower than the specified value shown in
the load current vs. ambient temperature graph.
Take proper measures so that the heat sink will be protected from
dust.
