For information about the equipment dimensions, refer to the Technical Specifications
Chapter.
The equipment is designed for outdoor installation in proper panel. The panel must be
designed for the environmental conditions to which it is subject.
The DR60 should always be sheltered from the weather. For indoor use, the equipment
must be installed inside panel with IP41 (IEC) enclosure protection or minimal type 3
(NEMA). For outdoor use, the equipment must be installed inside panel with IP55 (IEC)
enclosure protection or type 3, 3X, 3S or 3SX (NEMA), according to the local
environmental conditions, complying the IEC 60529 and NEMA 250-2003 standards
requirement.
The panels should be submitted to insulation test according to IEC 60255-5 standard
(minimum insulation resistance of 10 MΩ and be submitted to test of dielectric voltage
insulation of 2kV a.c.)
An additional panel designed for the DR60 application environment may be provided
upon request. For more information on panel options, please contact GE Contact
Center.
It is recommended that 1 rack unit of space (1.75") be kept unpopulated and free of
equipment above each DR60 to allow for a small amount of convectional airflow.
Although forced airflow is not necessary, any increase in airflow will result in a
reduction of ambient temperature that will improve long-term reliability of all
equipment mounted within the rack space.
This section describes the type of wiring and connections that should be used when
installing the device, as well as pin-out details.
Before carrying out any work on the equipment you should be
familiar with the Safety Section and the ratings on the equipment's
rating label.
In order to meet the EMC CISPR22 emission levels, the power supply, CT, VT and binary
signals connection shall use screened (shielded) cables with screen coverage of 70%;
Core wires should have 2.0 mm² cross section and be as short as possible; The shield
