Agency Compliance
The S55 is designed to comply with the following safety and agency requirements.
NEBS (Network Equipment Building Systems) Compliance
•
Shielded cables must be used for ports 0 - 43.The shields must be grounded at both ends.
•
Only reverse air flow configurations may be used in a NEBS compliant installation. Use only AC
supply S55-PWR-AC-R, DC supply S55-PWR-DC-R and Fan Only S55-FAN-R, Systems S55-44T-
AC-R and S55-44T-DC-R.
•
Power supplies and fan modules must be fitted with the S55-PWR-FLTR kits. Fan filters must be
replaced on a regular basis.
•
This equipment is intended to be used with an external second-level 6kV lightning SPD (Surge
Protective Device) at the AC input of the building.
•
For the NEBS compliant installation, AC power connections shall use a SPD (surge protection device)
in order to protect the AC power supplies from damage to excessive power line surges.
