WARNING:
Installation of electrical control equipment is subject to many regulations including
national, state, local, and industry guidelines and rules. General recommendations
can be stated but it is important that the installation be carried out in accordance
with all regulations pertaining to the installation.

Fuse and Circuit Breaker Selection
In general, fusing must be designed to protect the weakest link from fire hazard. Each Geo drive is
designed to accept more than the recommended fuse ratings. External wiring to the drive may be the
weakest link as the routing is less controlled than the drive’s internal electronics. Therefore, external
circuit protection, be it fuses or circuit breakers, must be designed to protect the lesser of the drive or
external wiring.

weakest link as the routing is less controlled than the drive’s internal electronics. Therefore, external
circuit protection, be it fuses or circuit breakers, must be designed to protect the lesser of the drive or
external wiring.
High peak currents and high inrush currents demand the use of slow blow type fuses and hamper the use
of circuit breakers with magnetic trip mechanisms. Generally, fuses are recommended to be larger than
what the rms current ratings require. Remember that some drives allow three times the continuous rated
current on up to two axis of motion. Time delay and overload rating of protection devices must consider
this operation.
