Mounting The 8LS

The 8LS consists of a 1/4 DIN housing with a front plug in electronics

module. The 8LS-OF (Open Frame) is suitable for sub-plate mounting

inside an enclosure without a front panel. An 8LS-DK will supply the

front panel keyboard with a 10-foot plug- in cable.

For optimum performance when directly connecting thermocouple

inputs, the unit should be protected from thermal shocks whenever

possible. This will minimize any temperature gradients across the

terminal strips and ensure the highest accuracy.

1. Use the dimensions below to cut a hole in the panel.

Cut the hole carefully; the 1/4 DIN specification only allows a front

panel of 96mm x 96mm [3.78in x 3.78in], so there’s not a lot of room

for error.

2. After the hole is cut, insert the 8LS through the front of the panel and

screw the top and bottom clamps into place. If excessive vibration is

anticipated a rear support may be required both for the 8LS and the

interconnecting cables.
