2.1. Input Power Connections

2.1. Input Power Connections
The SI4 has one DC input power connector for control power. For a full list of electrical specifications,
refer to Section 1.1. Refer

2.1.1. Control Supply Connector

The Control Supply input supplies power to the communications and logic circuitry of the SI4 . The +24V
input is connected to an internal fuse. Refer to
an isolated DC supply, connect 0V to protective ground at the supply. Use twisted pair wiring to
minimize radiated noise emissions (refer to
IMPORTANT: Refer to local electrical safety requirements to correctly size external system
wires.
