The cable lengths in Table 2 and Table 3 represent the total wire impedance allowed to help ensure proper operation of the safety monitoring relays
used in the isolation system. Consult Rockwell Automation for cable lengths when series connecting System Multiplexer / Permissive Modules.
NOTE: When series connecting the System Multiplexer / Permissive Modules, two maximum cable lengths must be taken into consideration. One
cable length is the maximum distance from the Control Module to the last series-connectedSystem Multiplexer / Permissive Module. The other cable
length is the RLS circuit length. See Appendix C of the Electro-Guard
®
User Manual regarding length calculation, conductor sizing and installation
scenarios.
IMPORTANT: The System Multiplexer / Permissive Module can support a maximum of 60 RLSs by using six 10-port Expansion Modules.
IMPORTANT: Connector plugs provided on ElectroGuard® Control Modules and System Multiplexer / Permissive Modules are factory shipped with two jumper
wires installed (see Figure 4). These two jumper wires must be removed and discarded when wiring is performed to connect a Remote Lockout Station to the
connector plug. Failure to remove the two jumper wires prevents proper operation of the RLS "System Isolated" indicator light.
IMPORTANT: When routing the cables from the Remote Lockout Stations to the System Multiplexer / Permissive Module, care must be taken to protect the
cables from physical damage and cable must be run in conduit when outside enclosed.
IMPORTANT: Cables to the System Multiplexer / Permissive Module must not run adjacent to power conductors or be run in a line voltage wireway.
The EXB1 connector provides control power and allows the interface to the System Multiplexer / Permissive Module from the Control Module in the
ElectroGuard
®
Power Panel. This is accomplished by wiring from the EXB1 connector at the System Multiplexer / Permissive Module to any one of
the RLS ports on the Control Module. The EXB2 thru EXB4 connectors allow the interface of the System Multiplexer / Permissive Module to
additional ElectroGuard
®
Power Panels. This is accomplished by wiring from the EXB2 thru EXB4 connectors at the System Multiplexer / Permissive
Module to any one of the RLS ports on the Control Module in the other ElectroGuard
®
Power Panels. See Section 3.
The EXB2 thru EXB4 connectors also allow for the series connection of up to three System Multiplexer / Permissive Modules. This is accomplished
by wiring from the EXB2 thru EXB4 connectors at the System Multiplexer / Permissive Module to the RLS_A connector of the series added System
Multiplexer Module. See Figure 7, Section 3.
System Multiplexer / Permissive Module Cable Specifications
IMPORTANT: · Cable must have copper conductors only.
· Cable with 600V insulation is required.
· Oil resistant cable is recommended.
· Individual conductors within the cable should be color-coded or otherwise clearly marked (see Table 1).
· Cable must have a shield with a drain wire.
· Type of wire for EXB_ to RLS connector or similar:
ALPHA wire "XTRA-GUARD
®

- Part No. 25450/9 for #14 AWG, 0.64" O.D.
- Part No. 25440/9 for #16 AWG, 0.61" O.D.
- Part No. 25430/9 for #18 AWG, 0.55" O.D.
· Type of wire for PLC1EXB connectors or similar:
ALPHA wire "XTRA-GUARD
®
2
- Part No. 25450/25 for #14 AWG, 0.98" O.D.
- Part No. 25440/25 for #16 AWG, 0.93" O.D.
- Part No. 25430/25 for #18 AWG, 0.80" O.D.
IMPORTANT: The maximum total cable length values shown in Table 2 must not be exceeded, as this may result in unreliable operation of the ElectroGuard
®
.
Consider using an Expansion Module if cable lengths greater than those shown are needed (See APPENDIX C of the Manual for wiring examples).
