7-4-1 Circuit protector
When installing a circuit protector dedicated for the control power input, use a circuit protector with
inertial delay to prevent malfunctioning in respect to the rush current generated when the power is
turned ON. The size and conductivity time of the rush current fluctuate according to the power supply
impedance and potential.

7-4-2 Relays
Use the following relays for the input/output interface (motor brake output: MBR, contactor output: MC,
external emergency stop : EMGX.)
Interface name Selection example
For digital input signal (EMGX) Use a minute signal relay (twin contact) to prevent a contact defect.
<Example> OMRON: G2A type, MY type
For digital output signal (MBR, MC) Use a compact relay with 24VDC, 40mA or less.
<Example> OMRON: MY type
