• Substitution of components may impair
suitability for Class I, Division 2.
• Do not replace components unless power
has been switched off or the area is known
to be non-hazardous.
• Do not disconnect equipment unless power
has been switched off or the area is known
to be non-hazardous.
• Do not disconnect connectors unless
power has been switched off or the area is
known to be non-hazardous. Secure any
user-supplied connectors that mate to
external circuits on this equipment by using
screws, sliding latches, threaded
connectors, or other means such that any
connection can withstand a 15 Newton (3.4
lb.) separating force applied for a minimum
of one minute.
• Batteries must only be changed in an area
known to be non-hazardous.
