Install external components using the guidelines in the following sections.
4.1 Installing an AC Input Disconnect
An AC input disconnect must be provided in the incoming power lines in accordance
with NEC/CEC guidelines.
4.2 Installing Branch Circuit Protection
Install the required, user-supplied branch circuit protection fuses according to
NEC/CEC guidelines. Refer to table 4.1 for recommended fuse ratings.
!
ATTENTION: The NEC and CEC require that an input disconnect be
provided in the incoming power lines. Failure to observe this precaution
could result in severe bodily injury or loss of life.
!
ATTENTION: The NEC/CEC requires that upstream branch protection
be provided to protect input power wiring. The input fuse ratings listed
in table 4.1 are applicable for one VSM500 unit per branch circuit. No
other load can be applied to that fused branch circuit. Failure to observe
this precaution could result in severe bodily injury or loss of life.
