The case of a RM3-400/410/420 Series dc power system is a fire enclosure as specified in UL 60950-1. The
system is to be installed in an enclosed cabinet.
•
The dc power system may be powered from multiple ac sources. All power sources must be isolated
before internally servicing the equipment.
•
The dc power system must be connected to a suitable and readily accessible disconnect device(s). The ac
plug may be suitable as the disconnect device. See details on page 14.
•
The dc power system is not compatible with IT (Impedance Terra) ac supply. For advice see Worldwide
Support on page 79.
•
A registered electrician (or suitably qualified person) must check the integrity of the installed cabling,
BEFORE the dc power system is powered up.
•
Tasks must be performed in the sequence documented in this guide.
Location and Environment
•
The RM3-400/410/420 must be installed in a Restricted Access Location (dedicated equipment rooms,
equipment closets, or similar) in accordance with the U.S. National Electric Code (NEC), ANSI/NFPA
No. 70, and according to the applicable local codes.
•
For ease of access and to maintain optimum system cooling, observe the clearances stated on page 17.
•
Ensure the ambient temperature and humidity are within the ranges in the Specifications on page 58.
•
Dust build-up within the RM3-400/410/420 may cause premature failure. In dusty environments filter
the ventilation air entering the equipment room. Ensure regular cleaning of the air filters.
•
Do not allow water or any foreign object to enter the RM3-400/410/420. Do not place objects containing
liquid on top of or near the unit.
Hazardous Energy Levels
•
Rectifiers and batteries contain hazardous energy levels. Only personnel trained and experienced in dc
power systems are to service/maintain this equipment.
•
Always use insulated tools.
•
Do not short-circuit the live and common bus bars or cables.
Rectifiers
•
Do not install the rectifiers until the room has been cleaned and is dust free.
•
To reduce the risk of electric shock and maintain optimum system cooling, always cover empty rectifier
slots with blanking panels.
•
To avoid electrical shock, do not place hands inside the rectifier magazine.
•
Rectifier cases may exceed 100ºC (212ºF), especially after prolonged operation. Use suitable gloves when
removing a rectifier from the magazine.
