1.5 Installation
W ARNING : Care should be exercised to route SQC-122 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-122 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.
