Specific Safety Precautions
DANGER!
RISK OF ELECTRICAL SHOCK, GENERAL
All ground connections must be installed and verified prior to connecting any power cables (AC or DC)
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.
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.
c)
Verify for AC hook-up, all enclosure circuit breakers are OFF and the utility incoming feed is OFF.
Use a trained licensed electrician.
DANGER!
RISK OF ELECTRIC SHOCK
The DC bus is 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.
Do not smoke.
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 CHEMICAL EXPOSURE
A battery can present harmful chemicals. Refer to the Battery Installation Manuals and MSDS supplied
with the batteries. Work in a ventilated area and follow all safety procedures.
At a minimum, wear safety glasses and gloves when working with batteries.
