The electronic I/O modules can be installed either on top of
the terminal blocks or on top of the manual terminal dis-
connect modules.
1. Make sure the sliding bus connector on the terminal block
is on the left side.
2. Mount the module onto the terminal block (or the manual
terminal disconnect module if installed) and make sure the
spring clip snaps on the little hook on the module housing.
3. Lock the safety latch on the terminal block (type A) (and
the manual terminal disconnect module, if installed; for the
safety latch on the manual disconnect module (type B), it is
recommended that you use a screwdriver or similar for
locking) as is shown in the figure.
Installing the XFR522A and XFR524A Manual
Override Modules
The manual override modules are installed on top of their
respective output modules. The XFR522A and XFR524A are
connected to the output modules via flat strip cable; this
allows opening the housing and setting the rotary HEX switch
under power without disconnecting the manual override
module.
The manual override modules are installed as follows:

1. Switch off the power to the output module; or unlock the
safety latch and unplug the module from the terminal block
as described in section "Removing Modules and Terminal
Blocks".
2. Remove the standard cover of the module housing
(XFL522B/XFL524B) as described in section "Setting the
Module Address".
3. Plug the manual override connector situated at the end of
the flat strip cable into the socket in the output module.
NOTE: By mechanical design, the plug can be inserted in
only one orientation, thus preventing wrong connec-
tion.
