Cables and Peripheral Devices
Current Suppression Devices
Inrush current suppression devices prevent equipment from being damaged by inrush current.
They are used only when using a SERVOPACK of 5 kW or higher (SGD7S-330A, -470A, -550A, -590A, or
-780A) with a DC power supply input.

External Inrush Current Suppression Resistors
Inrush Current Suppression Resistor Short Relays
*1. Connect two Relays in parallel. Also, maintain the same resistance between the DC power supply and SERVOPACK
for the wiring for each Relay.
*2. This Relay is applicable only when the temperature of the Relay installation environment is 50°C or less.
