CANOGA PERKINS 9145EMP Interface Device Quick Start Guide - Manual (Page 2)

General Safety Considerations
Installation
The 9145EMP is suitable for installation in Network tele-
communication facilities and locations where the National
Electric Code (NEC) applies.
Cabling
The 9145EMP has been designed and tested and has
passed all the pertinent sections of GR-1089 and GR-63 for
Type 2 and Type 4 equipment. This equipment does not
have direct electrical connection to outside plant equip-
ment.
The Copper (RJ45) ports of the 9145EMP are not intended
for direct connection to “Outside Plant” metallic conductors
and shall be isolated (by channel banks or office repeaters)
from any connections to network or terminal equipment that
lie outside of the same building. The telecommunication
interface connections are considered to be, and meet the
requirements of, SELV circuits (not TNV).
Power
WARNING: The 9145EMP with redundant power supplies
must have both power supply cords disconnected before
servicing.
Wiring methods used for the connection of the equipment to
the AC or DC MAINS SUPPLY shall be in accordance with
the National Electrical Code, ANSI/NFPA 70, and the Cana-
dian Electrical Code, Part I, CSA C22.1.
The 9145EMP AC and DC units do not incorporate a dis-
connect device. The plug on the power supply cord is
intended to serve as the disconnect device. It is also recom-
mended that the AC socket-outlet shall be installed near the
equipment and shall be easily accessible.
The 9145EMP DC has a nominal operating DC voltage of
48 VDC and passes the minimal steady state DC operating
voltage of 40 VDC in accordance with GR-1089 Issue 4
which References American National Standards Institute
(ANSI) T1.315, Table 1. Additionally, Canoga Perkins
design allows for a minimal steady state of 36VDC. The
9145EMP DC model is configured for a DC-I, Isolated DC
return.
Fuses
The 9145EMP is equipped with internal fuses. The AC
model is fused at 2A and the DC at 3A slow blow.

External fuse recommendation
The 9145EMP is equipped with an internal 3A slow blow
fuse. Although not required, an external fuse may be used
to isolate the unit in a shared fuse distribution panel. Based
on the 9145EMP in rush power characteristics, the mini-
mum fuse ratings are as follows: Slow Blow Fusing: 3A
slow blow fuse for all DC input voltage (48VDC or 24VDC)
Fast Blow Fusing: 5A fast acting fuse for DC input voltages
(48VDC or 24VDC)
Grounding
The 9145EMP AC & DC models are suitable for installation
as part of the Common Bonding Network (CBN).The
9145EMP AC and DC are provided with a safety ground
connection which is capable of conducting any fault current
likely to be imposed such as fault current from sources
within the chassis. For the DC model use an approved 18ga
insulated wire connected to the terminal block’s middle con-
ductor. The plus and minus conductors should be a mini-
mum of 20ga. The AC will be grounded via the ground
conductor of the power cord and must be connected to an
earthed mains socket-outlet.
An electrical conducting path should exist between the
9145EMP chassis and the metal surface of the enclosure or
rack in which it is mounted or to a grounding conductor.
Electrical continuity should be provided by using thread-
forming type mounting screws that remove any paint or
nonconductive coatings and establish a metal-to-metal con-
tact. Any paint or other nonconductive coatings should be
removed on the surfaces between the mounting hardware
and the enclosure or rack. The surfaces should be cleaned
and an antioxidant applied before installation.
Lightning Protection
The intra-building ports of the 9145EMP are suitable for
connection to intra-building or unexposed wiring or cabling
only. The intra-building port(s) of the equipment or subas-
sembly MUST NOT be metallically connected to interfaces
that connect to the OSP or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE, Issue 4) and
require isolation from the exposed OSP cabling. The addi-
tion of Primary Protectors is not sufficient protection in order
to connect these interfaces metallically to OSP wiring.
To protect the port against intra-building lightning surges,
the RJ45 ports of 9145EMP are suitable for connection to
shielded intra-building cabling grounded at both ends.

Surge Protection
The AC powered 9145EMP does not contain an internal
Surge Protective Device. An external Surge Protective
Device (SPD) should be used at the AC input of the net-
work equipment according to facilities procedures and as
defined by the National Electric Code (NEC).
ESD
The 9145EMP has been tested and passes the ESD
requirements of Test level 4 for air and contact discharges.
However to protect the exposed components from electro-
static damage when removing or replacing the SFP optical
modules requires the proper use of static mitigation proce-
dures such as properly wearing a wrist strap.
Operation Temperature
The 9145EMP is designed and Nationally Recognized Test
Laboratory (NRTL) tested and verified to operate between
0°C to 50°C, and type tested for short-term ambient tem-
perature of -5°C to 55°C
Fans
The 9145EMP models equipped with fans are constructed
with a mid-front to mid-rear (EC class F2-R2) airflow
scheme i.e. draws air from the front and exhausts to the
rear.
The 9145EMP models equipped with redundant fans are
designed to function normally over the entire long term
operating temperature range; in the unlikely event of a sin-
gle fan failure the 9145EMP will continue to perform nor-
mally over the long term operation temperature range until
a replacement can be installed.
Fan replacement cannot be performed in the field. Call
Canoga Perkins for an RMA number to arrange a repair.
Double Pole/Neutral Fusing
On the 9145EMP a fuse may be in place in the neutral path
on the AC power supply. After operation of the fuse, parts of
the equipment that remain energized might represent a
hazard during servicing.
