■ Interference
The SJ-HA Series may not operate properly if there is any conductive object close to the SJ-HA
Series or if another SJ-HA unit is installed closely together. Refer to the following illustration and iso-
late the SJ-HA Series from the conductive object.
If two SJ-HA units are used, refer to the following illustration and separate the static elimination bars
properly.
■ Auxiliary support part (SJ-H132A/156A/180A/204A/228A/252A/300A)
Install the SJ-H132A/156A/180A/204A/228A/252A/300A with auxiliary support part. Auxiliary support
part prevents the static elimination bar from bending. Do not install the SJ-H132A/156A/180A/204A/
228A/252A/300A without using auxiliary support part.
■
Cables
The cables, including power cables and connector cables, required for the SJ-HA Series are not
included in the package. Confirm the installation location before installing and make sure to buy the
proper lengths of cables (10 pin I/O cable, 10-to-10-pin cable and 10-to-10-pin for SJ-H036A
cables).
■ Installing SJ-HA Series
Install the SJ-HA Series in places where a static problem occurs or may occur.
• When installing the SJ-H132A/156A/180A/204A/228A/252A/300A, mount and secure the
auxiliary support parts with screws for the prevention of the static elimination bar from
bending, otherwise the static elimination bar may be broken.
See “Precautions for installation” (page 2).
• Keep a space of at least 10 mm around the static elimination bar after installation, other-
wise the static elimination bar may malfunction or receive damage.
1
Mount the auxiliary support parts on top of the static elimination bar or along the guide rails.
The SJ-H132A/156A/180A/204A requires a single auxiliary support part, the SJ-H228A/252A/
300A requires two auxiliary support parts. Mount them at approximately equal intervals.
Confirm that the hooks on the auxiliary support part grasp the guide rails on the static
elimination bar when installing.
2
Attach the end unit to each end of the static elimi-
nation bar.
3
Secure the SJ-HA Series with M4 screws at the
desired installation position.
When installing the SJ-H132A/156A/180A/204A/
228A/252A/300A, secure the auxiliary support
part with M4 screws as well.
When removing the auxiliary support part, be sure to
remove it from the side along the guide rails.
* The blue wire and orange wire are insulated from each other.
* There are two wires each for the brown wire and the blue wire.
Be sure to connect both of the two wires. The ends are sol-
dered together before shipping.
Do not short-circuit the output signal wire and output signal GND wire together without any
load, otherwise the internal circuit will be damaged, which may result in product
malfunctions, because the SJ-HA Series does not have any overcurrent protection circuit.
