1.5 Installation

WARNING: Care should be exercised to route SQC-122c cables as far as practical from

other cables that carry high voltages or generate noise. This includes other line voltage

cables, wires to heaters that are SCR-controlled, and cables to source power supplies

that may conduct high transient currents during arc down conditions.

Rack

Installation

The SQC-122c occupies a 5.25” high, half-rack space. An

optional installation kit is available to adapt to a full rack (see

Chapter 4). Install the unit in a 19” rack with the supplied

hardware.

Power

Connection

The SQC-122c automatically detects mains voltages of 100-

120 and 200-240VAC, 50/60Hz.

WARNING: Verify that the power cable provided is connected to

a properly grounded mains receptacle.

Sensor Input

Connections

Connect the BNC cables and oscillators from your vacuum

chamber feedthrough to the desired SQC-122c sensor inputs.

Source Output

Connections

Connect the BNC cables from the SQC-122c output

connectors to your evaporation supply control input.

Digital I/O
