Associated Equipment
AC30V series Variable Speed Drive
Dynamic Braking Resistors
We can supply suitable braking resistors, found on the following pages. Alternatively, you can use the calculation on page 5-5 to help you
select alternative resistors.
We recommend using a thermal overload switch to protect the braking circuit. Refer to page 5-4.
The AC30V unit must be fitted with external braking resistors if braking is required
.

WARNING
Do not apply external voltage sources (mains supply or
otherwise) to either of the braking terminals: DB+, DB. This can
lead to damage to the drive and installation, and risk to
personnel.
