Contemporary Research MOD HUB series Manuale Utente

Before removing the modules from the MOD HUB, turn the unit
off by depressing the power switch located on the front panel of
the MOD HUB. Unplug the power cord from the wall outlet.
Disconnect the cables from the connectors on the module that is
being removed.

Loosen the module from the MOD HUB unit by unscrewing
both of the captive screws with your fingers. The captive screws
are located on each end of the module. Loosen the captive
screws until they are unthreaded to the point where they hang
freely from the module.

With your fingers, grasp each of the module's captive screws
and pull the module out of the MOD HUB unit until it is free
from the unit. (If you are removing a blank panel, simply
unscrew the two fasteners.)

Before installing modules into the MOD HUB, turn the unit off
by depressing the power switch located on the front panel of the
MOD HUB. Unplug the power cord from the wall outlet.

Remove any of the blank panels or modules being replaced from
the MOD HUB. Unpackage the module to be installed into the
MOD HUB, taking care not to harm the module.

Grasp the module by the faceplate (with the circuitry on the
module facing to the left) and gently place the module into the
empty slot on the MOD HUB. Push the module into the MOD
HUB (you may need to exert some force to seat the module into
position) until the module's face plate is seated against the unit.
