Notes

When the relays are used to switch inductive loads (relays, contactors, motors, etc), connect an RC network or Varistor parallel to the load to suppress voltage spikes.

For safety, it is recommended to use fuses for the circuitry that is switched by the relays. The fuse specification must be within the specified contact limits.

Please use shielded wires to avoid interferences and connect the shield to ground.

The ends of wires must be tinned or crimped.

To avoid interference, route the extension card wires separately and as far away (at least 15cm) as possible from other control wires, motor wires and power wires, etc. Where these wires must cross each other, please make sure they are at a 90o angle.

Always use and operate this product within the limit of its specifications.
