Electrical Installation
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 replacing 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
installation and wiring must be made by a Qualified Person
1
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.
Connection to a Machine
Electrical installation must be made by qualified personnel
2
and must comply with NEC (National Electrical Code), NFPA 79 or
IEC/EN 60204-1, and all applicable local standards. It is not possible to give exact wiring instructions for a device that interfaces to a
multitude of machine control configurations. The following is general in nature; it is recommended to perform a risk assessment to
ensure appropriate application, interfacing/hookup, and risk reduction (see ISO 12100 or ANSI B11.0).
Access the Wiring Chamber
Access the wiring chamber via the hinged door.
1. To open the wiring chamber, insert a flat screwdriver blade into the slot in the cover and pry the cover open.
2. Select the best wiring entrance, and remove the knockout.
3. If required, thread in the 1/2 in x 14 NPSM conduit adapter (supplied) or the optional M20 × 1.5 cable gland.
To connect wires to the terminals:
1. Insert the screwdriver blade (flat, 2.5 mm) into the slot next to the desired wiring terminal.
2. Twist the screwdriver blade 45° in the slot to open the terminal jaws; insert the wire (6 mm to 8 mm bare wire or wire ferrule).
3. Hold the wire in place and remove the screwdriver.
4. Make sure that all wires are securely held and will not short to adjacent terminals (that is, no bent or stray strands of wire).
5. Snap the access cover shut (a click will be heard). Banner recommends securing the access cover with the supplied #2-28 ×
0.25 screw to hinder unauthorized access and ensure IP67 environmental rating (do not over tighten the screw).

Hookup
These rope pull switches have redundant pairs of safety contacts, so they may be wired for either single-channel or dual-channel
hookup to a safety module, safety controller, or E-stop circuit. Monitor contacts may be wired as desired to an external alarm device.
A risk assessment will determine the appropriate level of safety circuit performance (integrity) and the means of interfacing the
switch(es) with the machine control circuit.
Single-Channel Hookup:
Wire contacts 21/22 and 41/42 in series to the input of a safety module or E-stop circuit.
Dual-Channel Hookup:
Wire contacts 21/22 and 41/42 independently to the inputs of a dual-channel safety module as show in
on p. 7.
