2.4 Installation of stand-alone AGLAS Masters
2.4.1 Installation in the Control Cabinet
NOTE: The AGLAS Master is designed for protection class IP 20 (NEMA 1) according to IEC 529 and is approved for contamination
grade 1 according to IEC 60 664-1 (operation in dry air-conditioned spaces).
The environmental conditions are defined in “Technical Specifications” on page 27.
The airflow is from front to back through the AGLAS units so ensure there is ample room behind the units for proper cooling and
air flow.
The devices should be mounted on rails, brackets or tilting racks. They are to be fixed with the 4 clamp bolts positioned on the
front.
The ground cables of the AGLAS Masters must be connected to the bus bar in the electrical cabinet.
The control cabinet bus bar must be connected by a wire with a minimum cross-sectional area of AWG 0 (50mm
2
) to the central
earth ground in the control room.
2.4.1.1 Power Supply
The power cable (18 AWG (0.75mm
2
) recommended) is to be provided by the user. The plug supplied is to be attached to the
cable. The cable is used to connect the mains socket POWER at the rear of the AGLAS Master to the cabinet power supply.
Each AGLAS Master must be individually fused with a 10 A circuit breaker.
(For the location of the power socket, refer to “Rear View with Connections” on page 11).
2.4.1.2 Connection to the Series Circuit
The high-voltage connections “FIELD” and “CCR” on the AGLAS Master are each pre-prepared with cables with a length of 19-in
(0.5m), in accordance with the FAA L-824 specification.
The plugs on the built-in cables “CCR” are connected to the sockets on the extension cables going to the CCR. The latter have to
be separated in the middle beforehand. The extension cables must be shortened to the appropriate length and mounted on the
cabinet terminal strip. From there the connection to the Constant current regulator is made.
The connections from the control cabinet to the Constant current regulator are to be established on site.
The sockets on the built-in cables “FIELD” are connected with the plugs on the extension cables. The free ends of these extension
cables are to be shortened to the appropriate length and mounted on the cabinet terminal strip. From there the connection is
established to the series circuit cables, which lead to the airfield.
(For the location of the series circuit connectors: refer to “Rear View with Connections” on page 11).
2.4.1.3 Over-voltage Protection
When installed on a CCR of 20kW or greater, the CCR contactor wiring shall be run through the AGLAS over-voltage contactor.
Shown in Figure 5.
