setup. There is no limitation for the total length of series connection cables when the GL-RHG is
connected in series.

The sum of the length for all of the unit connection cables, extension cables and series connection
cables must be 30 m or less.
(2) Minimum cable bending radius : 5 mm
(3) Identification of connector cables

DANGER
• Cables must be within the lengths specified. Failure to follow this specification may cause
improper operation of safety functions, and may create a dangerous situation.

safety features may not operate properly. Do not allow this to happen as it is extremely
dangerous.
