Making Electrical Connections
All electrical connections are made without DC input power
applied to the system.
Observe the Following Admonishment
DANGER! This product requires Safety Extra-Low
Voltage (SELV) Inputs. A SELV input (based on the
safety requirements for Information Technology
Equipment Standards, such as UL1950, IEC 950) is a
secondary circuit which is so designed and protected
that under normal and single-fault conditions, the
voltage between any two paths of the SELV circuit or
circuits and for Class 1 equipment (provided with a
protective earthing conductor from the building),
between any one such part and the equipment
protective earthing terminal does not exceed a safe
value (42.4 V peak or 60 Vdc under normal conditions).
It is separated from the primary or mains supply by
Double (insulation comprising both Basic and
Supplementary insulation) or Reinforced insulation (a
single insulation system which provides a degree of
protection against electric shock equivalent to Double
insulation).
DANGER!
DO NOT apply power to the system until all
electrical connections have been completed and
checked.
DANGER!
To minimize voltage potentials inside the
cabinet during installation, connect leads to the cabinet
first, before connecting leads to the external source.
Wiring Considerations
All wiring and branch circuit protection should follow the current
edition of the American National Standards Institute (ANSI)
approved National Fire Protection Association's (NPFA) National
Electrical Code (NEC), and applicable local codes. For operation in
countries where the NEC is not recognized, follow applicable
codes. For field wiring, use wires suitable for at least 75°C.
586505000/586505500 Main and Expansion Cabinet
Grounding Connection (586505000/586505500 only)
A frame ground stud is provided on the rear of the cabinet. Refer
to Figure 7 for location. Recommended wire size is 14 gauge.
Recommended torque is 23 in-lbs. Provide a grounding
connection to this stud.
586505000/586505500 Main and Expansion Cabinet
DC Input Power Connection (586505000/586505500 only)
DC input power connections are made to the two-position
terminal block located on the rear of the cabinet. Connections
should be made using 18 gauge or 16 gauge stranded wire. The
ungrounded input lead should be fused at 3 amperes.
Refer to Figure 7 for DC input power terminal block location and
identification. The DC input power terminal block accepts a wire
size in the range of 22 to 14 gauge. Recommended torque is 12
in-lbs.
Connect the positive DC input lead to the terminal designated +
(positive).
Connect the negative DC input lead to the terminal designated -
(negative).
