7.1GENERAL

Warning! High voltage! Shock hazard. Properly lock- out/tagout the electrical service and all other energy sources before working on or near the machine.

For testing control circuits only, the service power shutoff switch (located inside the auxiliary panel) may be used to de-energize the system in lieu of normal lockout/tagout procedures. Use extreme caution when using this alternative.
