SAFETY 

 
1. 

Only  personnel  who  are  properly  trained  and  have  adequate  knowledge  and  skill  related  to  this  product 
should undertake any troubleshooting and repair. 

2. 

It must be assumed at all times that POWER is "ON" so all conditions must be treated as live. This practice 
develops a caution that may prevent an accident.  Follow posted lockout procedures. 

3. 

REMOVE LOAD from circuit or equipment before and after maintenance/troubleshooting. 

4. 

Equipment—NOTE: Test equipment must be checked at regular intervals. 

5. 

Capacitors MUST be given time to discharge, otherwise it should be done manually with CARE. 

6. 

When troubleshooting "LIVE" equipment, the necessary precautions must be taken as follows: 

a. Follow written safe operating practices. 
b. MAKE CERTAIN your tools and body are clear of Ground.  
c. Use extra PRECAUTION in DAMP areas. 
d. BE ALERT and work without any outside distraction. 

7. 

BEFORE applying POWER to any equipment, it must be established without a DOUBT that all persons are 
CLEAR. 

8. 

Any  CONTROL  PANEL  DOORS  shall  be  open  ONLY  when  it  is  necessary  to  check  out  the  electrical 
equipment  or

 

wiring.  After  CLOSING  the  door,  make  certain  that  the  disconnecting  means  is  operating 

properly with the DISCONNECT HANDLE MECHANISM. 

9. 

ALL COVERS or junction boxes SHOULD be CLOSED before leaving any job. 

10. 

BEFORE STARTING, read and understand all WARNING markings and notices. 

11. 

READ all marking such as nameplates and identification plates. 

12. 

DO NOT alter circuits unless authorized to do so by the manufacturer. 

13. 

DO NOT alter or by-pass protective interlocks. 

14. 

DO NOT place jumper wires across fuses. 

15. 

DO NOT alter over-current protective devices. 

16. 

GROUND connections allow fault currents to flow directly into the ground instead of following through the 
body then into the ground. ALL ELECTRICAL APPARATUS MUST BE PROPERLY GROUNDED. 

17. 

Use CAUTION when connecting test equipment probes to test points. SHOCK HAZARDS could exist at the

 

test points or in the test point area and/or TRANSIENTS induced by the problems could cause a MACHINE 
ACTION. 

18. 

AVOID wearing a necklace, ring or chain that is made of a METALLIC substance. 

19. 

All electrical wiring and items related to electrical controls are, and shall always be, in compliance with 
current National & Local Regulations. 

 

PERSONAL PROTECTIVE EQUIPMENT 

 
When servicing, protect yourself by wearing protective equipment where required: 
1. 

Safety Glasses—Must be properly fitted and worn when a hazard exists.  

2. 

Gloves—Although  it  is  recommended  that  gloves  not  be  worn  unless  absolutely  necessary,  gloves  can 
protect the hands from cuts or abrasions caused by slings or sharp edges.  Do not use gloves when working 
on a tool with rotating equipment.
