Specific Safety Precautions
DANGER!
ELECTRICAL HAZARD
The equipment shall be installed and serviced by trained service personnel in accordance with the applicable requirements of
the current edition of the American National Standards Institute (ANSI) approved National Fire Protection Association's
(NFPA) National Electrical Code (NEC) (NFPA 70) or Canadian Electrical Code; and the applicable sections of the National
Electrical Safety Code (NESC) (ANSI C2). For operation in countries where the NEC or NESC is not recognized, follow
applicable codes.
All electrical procedures should be performed by a licensed electrician.
Observe all safety precautions as specified by local building codes. If local building codes specify procedures different from
those in this section, follow local codes.
DANGER!
RISK OF ELECTRICAL SHOCK, GENERAL
All enclosure grounding must be installed and verified prior to connecting any power cables and turning-up of enclosure.
When connecting any discrete power connection, make the connection first with the ground/return and break last with
ground/return.
Do not install equipment showing any physical damage.
If packaging is damaged, do not accept receipt from the shipper.
DANGER!
RISK OF ELECTRICAL SHOCK, AC
Proper actions, include, but not limited to:
a)
Verify before contacting the enclosure that no current leakage or ground fault condition is present.
b)
Verify a proper ground is in place.
DANGER!
RISK OF ELECTRICAL SHOCK, DC
An OFF battery switch / breaker does not isolate the batteries, nor do the batteries have a protective fuse. Thus, handle
accordingly and use only insulated tools when working around batteries or any DC potential.
In addition, be sure that all connection points have been de-energized.
DANGER!
RISK OF ELECTRICAL SHOCK, OSP CABLES
If joint buried cables are used, check the cable sheath for voltage in accordance with local standards. If voltage is detected,
do not proceed with the installation. Contact the supervisor and do not proceed until the voltage hazard is eliminated.
DANGER!
RISK OF ELECTRIC SHOCK
The DC bus may be powered by DUAL power sources – rectifiers and DC batteries.
To properly work on the system, de-energize by disconnecting BOTH power sources. Even with the batteries turned off by
using a local battery (circuit breaker) disconnect, batteries are still “LIVE” and hazardous, including a voltage >50 VDC, and a
source of high short circuit current.
Use extreme caution around the batteries and terminals.
WARNING!
RISK OF INJURY TO EYES AND SKIN, FROM OPTIC DEVICES
Do not look into a fiber cable or device, nor hold such cable or device against body, fabric or other material.
