Recommended Line Side Protection
The Bulletin 160 Smart Speed Controller has
been UL tested and approved for use with up to a
30 Amp protective device (fuse, circuit breaker,
manual motor starter) installed on the line side of
the drive for the purposes of branch circuit
protection. The ratings in Tables 2.B and 2.C are
the minimum recommended values for use with
each drive rating. The model numbers of the
devices listed in these tables are provided to serve
as a guide. Other devices which meet the
requirements of UL508C and UL489 with similar
trip characteristics may be used. For applications
with greater than five controllers per branch
circuit, consult factory for group fusing
recommendations.
Input Power Conditioning
The controller is suitable for direct connection to
AC power lines within the rated voltage of the
controller (see Appendix A). Listed below are
certain power line conditions which may cause
component damage or reduction in product life. If
any of the conditions exist as described in the
table below, install “one” of the devices listed
under the heading “Corrective Action” on the line
side of the controller. Note: Only one device per
branch circuit is required. It should be mounted
closest to the branch and sized to handle the total
current of the branch circuit.
