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.
