The ET100100180 Outdoor Base Station Cabinet is mainly used in communication base station, such as 4G system, communication/network integrated service, access/transmission switching station, emergency communication/transmission, etc.
2. Cabinet Introduction
2.1 Cabinet Material
The cabinet is made of galvanized steel, with double walls, thickness of outer plate: 1.5mm, thickness of inner plate: 0.8mm. There are heat insulation between inner wall and outer wall. The
insulation material is 40mm PEF. The cabinet is assembled type.
2.2 Cabinet Structure
The cabinet includes two compartments, with separated upper compartment and lower compartment. The upper
compartment is equipment compartment, including 19” rack, 30U space. The lower compartment is for managing cables.
2.3 Cabinet Door and Lock
The cabinet door uses embedded structure. The door opening angle is larger than 110°and the door limit device can limit the opening angle. The lock is theftproof three point lock, supporting padlock.
3.1 The cabinet is dustproof, sunproof and rainproof, which is used in outdoor environment.
3.2 The cabinet cooling use two air conditioners, which work in alternation to continuously keep thermostatic inside the cabinet.

9. Cabinet Installation
9.1 Position of installation hole at cabinet base is as the following diagram.
9.2 Users prefabricate concrete base.
9.3 Pre-embed 4pcs M10×100 anchor bolts on the concrete base. Distance between bolts are as that in diagram 1, with 40mm bolt exposed height. Put the cabinet on the concrete base, align anchor bolts, then screw on nuts, and tighten them with wrench.
9.4 According to site situation, put the cabinet on the concrete base with forklift, crane or manually, and fix it on the concrete base with bolts.
10. PDU Principle Diagram
10.1 PDU AC input voltage: 200 - 240VAC, DC input voltage: 45-56VDC.
10.2 AC MCB 63A/2P: Model: DZ47-63; Specs: 400VAC, GB10963.1, 3000A.
AC MCB 16A/1P: Model: DZ47-63; Specs: 230/400VAC, GB10963.1, 3000A.
DC MCB 16A/1P: Model: DZ47-63; Specs: 250VDC, GB10963.2, 3000A.
The cabinet packing is wooden case in compliance with GB3873-83, damp proof and shock proof. The outside of the packing is painted with damp proof sign, shock proof sign, direction sign, etc.
The cabinet can be transported by various transportation ways. During the transportation, the environment temperature should be -40°C~+70°C, the relative humidity should be ≤90%(at +30°C). There should be a awning to prevent the product from rain and sunshine. Loading, unloading and moving of the product should be carried according to the transportation signs painted on the packing.
