QUICK START GUIDE
Hardware Installation
4.1 Wiring
ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your switches.
2. Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
3. If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
4. Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
5. Do not run signal or communications wiring and power wiring through the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
6. You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring sharing similar electrical characteristics can be
bundled together.
7. You should separate input wiring from output wiring.
8. It is advised to label the wiring to all devices in the system.
4.1.1 Fault Relay
The three-pin fault relay terminal on the front panel is used to detect user-configured events. The
two wires attached to the fault contacts form an open circuit when a user-configured event is
triggered. If a user-configured event does not occur, the fault circuit remains closed.
4.1.2 Redundant Power Inputs
The switch has two sets of power inputs, power input 1 and power input 2. Follow the steps below
to wire redundant power inputs.
Step 1: Insert the negative/positive wires into the V-/V+ terminals, respectively.
Step 2: Secure the DC wires by using a small flat-blade screwdriver to tighten the wire-clamp
screws on the front of the terminal block connector.
