Powering Up the OWS
This section provides instructions for powering up the OWS from both an AC and DC power source.
Powering Up from an AC Power Source
Important Note (AC Power)
1.
Verify that the AC service voltage is 120 VAC to 240 VAC.
2.
Check that the power is turned OFF at the designated circuits.
3.
If necessary, install 1/2 inch liquid-tight conduit from the power source to within 3 feet of the OWS,
then connect the conduit to a junction box. The conduit and junction box must be IEEE/ANSI
compliant and suitable for outdoor use.
4.
Connect the OWS power cord to the AC supply.
5.
Close the enclosure’s door (the OWS door interlock will actuate).
6.
Turn ON the AC supply.
Powering Up from a DC Power Source
Important Note (DC Power)
1.
Verify that the DC service voltage is 12 VDC to 24 VDC.
2.
Check that the power is turned OFF at the designated circuits.
3.
If necessary, install 1/2 inch liquid-tight conduit from the power source to within 3 feet of the OWS,
then connect the conduit to a junction box. The conduit and junction box must be IEEE/ANSI
compliant and suitable for outdoor use.
4.
Connect the OWS power cord to the DC supply.
5.
Close the enclosure’s door (the OWS door interlock will actuate).
6.
Turn ON the DC supply.
AC input: 100 – 240 VAC (50/60 Hz) at 1.0 Amp maximum, supplied by a separate
branch circuit with 2 Amp over-current protection (2 Amp circuit breaker).
The OWS must always be grounded before applying power to the unit—see
Grounding
the OWS Enclosure on page 24
.
DC input: 12 – 24 VDC at 9.0 Amp maximum, supplied by an external separate 250 VA
power-limited (or less) and isolated DC source with 15 Amp over-current protection (15
Amp circuit breaker).
The OWS must always be grounded before applying power to the unit—see
Grounding
the OWS Enclosure on page 24
.
