NOTICE

to the disabling function of the switch.
With any padlock used to lock the

When installing the D4157 switch, use the wiring diagram
in Figure 2 to ensure proper wire connections.

Model D4157 Instructions

Machine

Verified
Ground*

This switch is intended to be connected to stranded
wire with insulated crimp-type ring wire terminals.

All crimps must be "pull-checked" to ensure that
wires are securely crimped and will not fall out
with moderate tension or when exposed to normal
machine vibration.

*The machine MUST be connected to a verified ground.
In the event of certain malfunctions or breakdowns,
grounding reduces the risk of electric shock by providing a
path of least resistance for electric current.

Disabling & Locking Switch

The ON/OFF switch can be disabled and locked
by inserting a padlock through the ON button, as
shown. Locking the switch in this manner can prevent
unauthorized operation of the machine, which is
especially important if the machine is not stored inside an
access-restricted building.

IMPORTANT: Locking the switch with a padlock
only restricts its function. It is not a substitute for
disconnecting power from the machine when adjusting or
servicing.

Children and untrained people can be seriously injured
by this machine. This risk increases with unsupervised
operation. To help prevent unsupervised operation,
disable and lock the switch before leaving machine
unattended! Place key in a well-hidden or secure
location.
