INSTALLATION NOTES
It is not necessary to install an E-ACVDRLY-xxx to monitor the AC circuit which provides power to the E-16D/-5D
B
/ -2D
B
.
These models have built-in power monitoring and battery backup and will send an alert in the event of a power failure.
In order for the ENVIROMUX System to send an e-mail alert, the attached network components (routers, mail server, etc.)
must have power. If you are using the SYSTEM and E-ACVDRLY-xxx to monitor the AC circuit providing power to any of
these network components, be sure they will not lose power during a fault condition. (See image below.)
Note: Because of the low 500mA rating, the E-ACVDRLY-xxx is not recommended for inductive or capacitive loads (even
very small loads), because the inrush current is likely to exceed the 500mA rating.
FYI: In the images below, the E-5DB \-2DB are indicated because they include the battery backup feature to provide
sensing and alert communication in the event of a SYSTEM power failure.
If your network components will lose power during the AC fault condition, use an alternate means to send alerts such as a
GSM Modem (E-GSM) or Auto Voice Dialer (E-AVDS). The E-GSM and E-AVDS are powered by the “Aux Pwr” port on the
E-16D/-5D(B)/-2D(B). (See image below.)
If you are using the E-ACVDRLY-xxx to monitor the AC Circuit which provides power to the E-MINI-LXO or any of the
necessary network equipment (router, mail server, etc.), be sure they will not lose power during the AC fault condition. (See
image below.) The method below would also be best suited for E-5D/ -2D (models without battery backup).
