Installation Requirements
Before you install an RM1250 unit, use the following information as a checklist to ensure a successful installation:
Power Disconnect and Branch Circuit Protection
:
A customer-supplied, power disconnect device is
required for the unit installation. The power disconnect device (such as a switch, main circuit breaker, or
other type of power disconnect) should provide an easy and accessible means for removing the main
input supply power source from the unit. Multiple-pole circuit breakers shall interrupt all neutral and
ungrounded connectors of mains supply simultaneously. The power disconnect device must be clearly
marked to identify it as the disconnect device for the unit. The power disconnect or separate
overcurrent protection device should also provide overcurrent protection in the form of a 20 amp fuse
or circuit breaker suitable for branch circuit protection per local codes and requirements.
