WARNING
Do not operate an SBN Pendant Pushbutton Station unless you are fully trained and qualified to operate the
overhead material handling system of which this SBN is a component. For applications other than overhead cranes
and hoists, consult Magnetek at 1-800-288-2178.
WARNING
Read the entire contents of this manual before you install or use the SBN Pendant Pushbutton Station.
CAUTION
Prior to installation, inspection, or repair of pendant stations disconnect power at source, following lockout/tagout
procedures as outlined in ANSI Z244.1.
WARNING
If the pendant cable grip is not properly sized to fit the pendant cable, contamination of the pendant housing is
possible. Contaminants that enter the switch contacts may result in a potentially unsafe operating condition.
When cutting, stripping, and installing wires, ensure that contaminants do not fall into the enclosure. Contaminants
that enter the switch contacts may result in a potentially unsafe operating condition.
Some pendant cable manufacturers add talc to their cable during the manufacturing processes. This talc can migrate
from the cable into the housing of the pendant station. As a result, contamination of the switch contacts may occur,
resulting in a potentially unsafe operating condition. Use only talc-free cable for the wiring of all pendant stations.
Remove all contaminants from the housing and switch contact areas prior to sealing the enclosure and putting the
pendant into service.
NOTE: The maximum ambient temperature rating for the SBN pendant is 40°C (104°F).

Installation and Wiring
Installation Precautions
x Do not expose the unit to cold blasts of air that might cause condensation (e.g., from an air
conditioner).
x Do not expose the unit to cleaning solvents that will penetrate and damage the unit's enclosure.
x Do not use cable that is split or cracked.
Hang the pushbutton station when installing it. Do not place it on a horizontal surface (for example, on a
stand or on the floor).
Attach the pushbutton station to the strain relief cable so that no tension is exerted on the pushbutton
conductors directly.
DANGER
HIGH VOLTAGES ARE PRESENT IN THE CONTROL PANEL, JUNCTION BOXES, PENDANT’S
ELECTRICAL COMPONENTS, AND THE CONNECTION BETWEEN THESE COMPONENTS.
Before installing, servicing, or inspecting any electrical or mechanical components of this power
equipment, power must be disconnected at the source and proper lockout/tagout procedures followed.
DO NOT make or break electrical connections (for example, plugs and receptacles) without first
disconnecting power at the source and following proper lockout/tagout procedures.
REFER TO ANSI Z244.1 PERSONNEL PROTECTION – LOCKOUT/TAGOUT OF ENERGY SOURCES.
Only qualified personnel should install components, inspect, and/or service this equipment.
Precautions for Wiring
x If the pendant top cable gland does not fit the connecting cable properly, water or dust may enter
the pendant case, get into the switches and cause damage to the switches. Damaged switches
may malfunction. Water inside the pendant can conduct electricity and close the switch contacts,
causing unintended run commands.
x When cutting or stripping wires, ensure that particles do not fall into that enclosure, as they can
jam switch mechanisms or close contacts by conducting across switch gaps.
x Use a UL-listed or CSA-certified, round, crimped-on terminal when connecting to terminals. Do
not solder the terminal onto the wire or connect the bare wires directly to the switch terminal
screws.
