Electrocution hazard
1. Shut off power at the main disconnect external to the analyzer.
2. Open enclosure door.
If service must be performed with power engaged (gain adjustment, etc.):
1. Note any live electrical components and avoid any contact with
them.
2. Only use tools with a safety rating for protection against accidental
contact with voltage up to 1000 V (IEC 900, ASTF-F1505-04, VDE
0682/201).
Explosion hazard
Any work in a hazardous area must be carefully controlled to avoid creating any
possible ignition sources (e.g., heat, arcing, sparking, etc.). All tools must be
appropriate for the area and hazards present. Electrical connections must not
be made or broken with power on (to avoid arcing).
Complete this action before performing any service that requires
working near the main input power or disconnecting any wiring or
other electrical components.
