SPECIFICATIONS
• Brown high temperature fiberglass reinforced composite box and cover (heavy duty)
• Nema 12: Below-grade enclosure for direct burial applications
• 2 foot 12/2 cable lead wire for low voltage connections (1 per circuit or voltage)
• In-line fuse protection for DB-12-75, Circuit breaker protection of all other models
• 3 available 1/2" NPS mounting hubs on cover, must specify which hole to tap at
time of order
• 120 volt primary, 12.5 volt secondary, 50/60 Hertz/cycle
SAFETY FEATURES
• Long life, high temperature (130° C) transformers
• Isolation/insulation type, no contact between 120V and 12V windings
• Single phase, open core and coil
• Completely potted for longer life, more efficiency and reduced noise
• Must be installed by a licensed electrical contractor per local codes
|
INSTALLATION
• All direct burial transformers must be accessible for servicing.
• Install at highest grade to allow water to run off -- Usually 1/2" to 1" higher
than grade.
• The preferred drainage material is pea gravel or sand.
• Do NOT allow water to gather near unit.
• Do not install in low grade areas.
• Do not install in turf applications unless a concrete border is installed to protect
from high impact.
• You can mount unit in a valve box, however there must be plenty of room for servicing
the unit.
• KEEP IN A DRY LOCATION, IF POSSIBLE!!!
• You can feed through to another DB unit or power source.
• You must specify at time of order if you want top holes drilled and tapped 1/2" NPS.
• Use proper liquid tight connections for feed wires.
