General Safety Instructions
WARNING
Lock Out/Tag Out:
Disconnect all sources of energy and lock out machine before doing any
maintenance or repairs to the machine. Proper Lock Out procedures will prevent the energy source from
starting the machine or allowing parts to move unexpectedly as well as prevent the machinery from being
accidentally turned on or restarted. Shut off and Lock Out all sources of potential or kinetic energy. These may
include, but are not limited to, electrical, mechanical or hydro energy sources.
Lock Out is a procedure used for placing an actual locking device on the power source, preventing unexpected
start up or accidental release of energy. Lock Out is the preferred method of accident prevention.
Tag Out procedure is used when the power can not be disconnected. Tag Out does not shut down the power
source, Tag Out only provides a warning about the danger of activating the machine.
Never try to operate machinery that is locked out or tagged out. Never attempt to remove these locks or tags on
machinery. Doing so will result in injury to personnel working on the machine. Only the initiator of the Lock Out or
Tag Out procedure may remove locks and tags.
Sometimes it may be necessary to energize the system to test or position equipment during maintenance or
repair. Such application must be performed only by a qualified technician and all Lock Out removal steps must be
followed before power is turned on.
WARNING
Main Disconnect:
The main power disconnect is located at the main service breaker or
generator. The disconnect at the panel is not the main disconnect. A fuseable service disconnect device
must be placed previous to this panel with the fuses sized for the load being supplied and installed in accordance
to NEC codes.
It is important to understand the differences between the Pivot Enable switch (if installed), High Voltage On/Off
switch and the service breaker On/Off throw switch.
The power company service disconnect provides the ability to turn off or return full service to the equipment from
the power company service line. This switch must be turned off and locked out when performing maintenance and
repairs on the system.
The High Voltage On/Off provides the ability to turn off or return power to the equipment from the service discon-
nect. This switch must be turned off and locked out in conjunction with the service disconnect switch. The High
Voltage switch only disconnects the power in the control panel, as energy is still coming in from the main power
line.
The Pivot Enable switch (if installed) provides power to the system controls. When enabled, the entire system and
the controls will power up. When turned off, the controls and system will not be energized. However, there will be
power in the panel circuitry. The Pivot Enable switch is
NOT a disconnect and should not be treated as such.
