Installing the FIK-50W
Device Installation
Follow these steps to properly mount the cabinet.
1.
On the mounting surface, install two screws level with each other 11" apart.

2.
Install the cabinet onto the two mounting screws and tighten the screws.
3.
Insert two screws into the two bottom mounting holes.
4.3.3 Wiring Specifications
All wiring and devices installed in the system must meet the standards described in National Electrical Code (NFPA 70), NFPA Standard 72,
and Life Safety Code (NFPA 101).
To avoid induced noise (transfer of electrical energy from one wire to another), keep input wiring isolated from high-current output and
power wiring. Avoid pulling one multi-conductor cable for the entire panel.
Instead, separate the wiring as follows:
DO NOT pull wires from different groups through the same conduit.
Twisted, shielded wire is recommended for all audio circuits to provide the maximum protection against EMI and AFI emission and suscep-
tibility.
If using shielded cable, attach the shield to earth ground on the control panel.
For the same reasons, wiring within the cabinet should be routed around the perimeter of the cabinet. It should not cross the printed circuit
board where it could induce noise into the sensitive microelectronics or pick up unwanted RF noise from the high speed circuits.
