4-2-1 How to Replace the Input/Output Terminal Block
Loosen the two terminal block replacement screws and pull the terminal block upwards. To install the new
terminal block, tighten the two terminal block replacement screws after attaching the terminal block and the
SL-R11E. (The recommended tightening torque is 0.4 N•m.)
WARNING
• Always turn off the power supply when performing electrical wiring.
• The two control outputs (OSSDs) provided in the SL-R11E must both be used to
build a safety system. Building a safety system with just one of these outputs
could cause the system not to stop due to a control output malfunction, which
could result in a serious accident, including serious injury or death to the ma-
chine operator.
• The AUX provided in the SL-R11E is not an output for the safety system, so it
cannot be used by connecting a control output (so called OSSD or MPCE) to
stop the machine. Using the AUX as an output to build a safety system to stop
the machine could result in the serious injury or death.
• When wiring the SL-R11E output terminals to the control circuit of a machine
containing the SL-C, check with the machine manufacturer to make sure the
wiring is appropriate for the machine being used to ensure that the machine can
be stopped correctly. If the wiring is not done correctly for the machine, a serious
accident, such as serious injury or death to the machine operator could result.
• Follow electrical articles, regulations, standards, and laws for the country or
region in which the SL-R11E is being used when performing electrical wiring.
• Do not place cables or electrical lines used in wiring the SL-R11E in the same
duct as high-voltage electrical or power lines or in parallel with such lines.
