Cascading amplifiers of the series connection type
*
Cascading is not available for FX-505□-C2.
● You can only cascade amplifiers of the series connection type, i.e.
FX‑501
□ and
FX‑502
□
.
●
Make sure that the power supply is OFF while adding or removing
amplifiers of the series connection type.
● If you cascade 2 or more amplifiers, make sure to mount them on a
DIN rail. Refer to “3 Mounting” for details.
● For each amplifier using a main connection cable you can install a
maximum of 11 additional amplifiers using sub cables.
● If you connect 2 or more amplifiers of the series connection type in
cascade, use the sub cable (optional) for the second series‑connec‑
tion-type amplifier and all after.
Cascading amplifiers
1.
Mount the amplifiers one by one on the
DIN rail.
2.
Slide the amplifiers next to each other
and connect the quick‑connection cables
(main cable for the first amplifier, sub
cables for all amplifiers after the first).
3. Mount the end plates
MS-DIN-E
(
1
,
optional) at both ends of the cascade so
that their flat sides hold the amplifiers
together.
4.
Tighten the screws to fix the end plates.

Removing cascaded amplifiers
1. Loosen the screws of the end plates.
2. Remove the end plates.
3.
Slide the last amplifier away from the oth
‑
ers and remove them one by one.
