•
Both AC and DC over-current protection must be provided as part of the installation.
o
Coordination of conductor sizes and over-current protection shall be done in
accordance with the
Canadian Electrical Code, Part 1.
o
NOTE – Breakers protect the wire, not the equipment.
•
Use only copper wires with a minimum temperature rating of 90°C.
•
The equipment ground is marked with this symbol:
DC Wiring
•
Minimize the number of connections between the Rosie and the battery bank. Exceptions
are the DC breaker
— required at the battery to protect the DC wiring — in the positive line,
and a DC shunt — to allow battery charge state monitoring — in the negative line. Additional
connections will contribute to voltage drops, and these extra connection points may loosen
during use.
•
DC cables should be tied together with wire ties or electrical tape approximately every 6”.
This helps improve the surge capability and reduces the effects of inductance, which
improves the inverter waveform and reduce
s wear of the inverter’s filter capacitors .
•
All wiring to the battery terminals should be checked monthly for proper torque/tightness.
If you don’t have a torque wrench, ensure all DC terminals are tight and cannot move.
•
The DC cables/wires must be color coded with colored tape or heat shrink tubing: RED for
positive (+); WHITE for negative (-) if solidly grounded or BLACK if using a GFP breaker; and
GREEN for DC ground.
•
Use the correct DC cable and corresponding circuit breaker to achieve maximum efficiency
from the system and reduce fire hazards associated with overheating.
The Rosie is designed for indoor installation or installation inside a weatherproof
enclosure. It must not be exposed to rain and should be installed out of direct sunlight .
CAUTION!
Ensure all sources of DC power (batteries) and AC power (utility or AC generator) are
de-energized (breakers opened, fuses removed) before proceeding — to prevent
accidental shock .
WARNING!
