CAUTION: MAKE SURE POWER IS SHUT OFF BEFORE WIRING!
Two removable terminal connectors are provided for simple wiring to WebRelay
TM
. The correct wiring procedure is
as follows;
1. Make sure power is turned off.
2. Remove terminal connectors from WebRelay
TM
and make wiring connections to the terminals.
3. Reconnect terminal connectors.
4. Apply power.
It is recommended that the load (device to be controlled) not be connected to WebRelay
TM
until after WebRelay
TM
has
been configured and tested. By doing this, wiring and configuration mistakes will not cause the load device to turn
on unexpectedly.
IMPORTANT: MAKE SURE WIRES ARE PROPERLY ATTACHED TO THE TERMINALS AND THAT THE
TERMINALS ARE TIGHT!
