• Remove the plexiglass cover to protect the SSR modules using a 4 mm hexagonal key, as shown in the
figure below:
• Disconnect the two wires from the terminal block of the SSR module. For this operation, use a flat-blade
screwdriver (recommended blade size 3.5 x 0.6 mm), type Phoenix Contact SZF 1-0.6X3.5 - 1204517 or
equivalent. Insert the blade into the appropriate seat of the terminal board and extract the cable. Mark the
cables to avoid inverting them during wiring.

following image:
• Remove the SSR module by sliding it upwards, disengaging it from the green interface connector with the
CPU board. Be careful not to pry up the connector to avoid damaging it, but try to pull it out horizontally.

uniform layer of thermoconductive paste (available on request).
• Fit the replacement module by inserting the connector fully.
