Verify that power has been removed from the EZ-SCREEN SLS and the guarded machine. Make the permanent electrical
connections as described in "Output Signal Switching Device (OSSD) Output Connections" on page 42 and "Final Switching
Devices (FSD) Interfacing Connections " on page 43 as required by each individual application.
Lockout/tagout procedures may be required (refer to OSHA 1910.147, ANSI Z244-1, ISO 14118, or the appropriate standard
for controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC, NFPA79 or IEC
60204-1.
Supply power and external device monitoring (EDM) should already be connected. The EZ-SCREEN SLS must also have
been aligned and passed the Initial Checkout, as described in "Initial Checkout Procedure" on page 35 .
The final connections to be made or verified are:
OSSD outputs (see "Output Signal Switching Device (OSSD) Output Connections" on page 42 )
FSD interfacing (see " Final Switching Devices (FSD) Interfacing Connections " on page 43 )
MPCE/EDM (see "Machine Primary Control Elements (MPCE) and External Device Monitoring (EDM) Input" on page
44 )
Remote Test
WARNING:
Risk of electric shock
Use extreme caution to avoid electrical shock. Serious injury or death could result.
Always disconnect power from the safety system (for example, device, module, interfacing, etc.),
guarded machine, and/or the machine being controlled before making any connections or replac-
ing any component. Lockout/tagout procedures might be required. Refer to OSHA
29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy.
Make no more connections to the device or system than are described in this manual. Electrical in-
stallation and wiring must be made by a
Qualified Person

and must comply with the applicable
electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or
IEC 60204-1, and all applicable local standards and codes.
Both the Output Signal Switching Device (OSSD) outputs must be connected to the machine control so that the machine's
safety-related control system interrupts the circuit or power to the Machine Primary Control Element(s) (MPCE), resulting in a
non-hazardous condition.
Final Switching Devices (FSDs) typically accomplish this when the OSSDs go to an OFF state.
Refer to the output specifications in the " Specifications " on page 12 and these warnings before making OSSD output con-
nections and interfacing the EZ-SCREEN SLS to the machine.
WARNING:
Interfacing both output signal switching devices (OSSD)
Failure to follow these instructions could result in serious injury or death.
Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES,
PC) between the safety module outputs and the master stop control element it switches such that
a failure causes a loss of the safety stop command or the failure allows the safety function to be
suspended, overridden, or defeated.
Connect both OSSD outputs to the machine control so that the machine’s safety-related control
system interrupts the circuit to the machine primary control element(s), resulting in a non-haz-
ardous condition.
