Requirements for the Installation Scenarios
Method of installation:
To ensure the heat dissipation of the DRH and waterproofing of the ports at the bottom of the DRH, the vertical deviation angle of a DRH must be less than or equal to 10 degrees, as shown in Figure 3-5.
U-steel and angle steel support the standard or reverse installation of a single DRH only.

3 Information About the Installation |
The diameter of a pole for installing a DRH ranges from 60 mm (2.36 in.) to 114 mm (4.49 in.). The recommended diameter is 80 mm (3.15 in.).
When the diameter of a pole ranges from 60 mm (2.36 in.) to 76 mm (2.99 in.), a maximum of three DRHs can be installed on the pole.
Only a pole whose diameter ranges from 76 mm (2.99 in.) to 114 mm (4.49 in.) supports more than three DRHs.
The recommended thickness of the wall of a pole is 3.5 mm (0.14 in.) or above.
A single DRH can be installed in either side-mounted or standard mode.Figure 3-7 shows a single DRH installed on a pole.
Figure 3-7 A single DRH installed on a pole
Two DRHs can be installed next to each other at the same level or vertically at different levels.Figure 3-8 shows two DRHs installed on a pole.

Installing a DRH on a Wall
The wall for installing DRHs must meet the following requirements:
For each DRH, the wall must be able to bear a weight four times the DRH's weight and the bolts' pulling force of 1.25 kN (281.25 lbf) vertical to the wall.
Expansion bolts must be tightened to 15 N·m (132.76 lbf·in.) so that the bolts stay secured without damaging the wall.

Installing a DRH on an IFS06
In an IFS06 scenario:
The upper and lower adjustable beams on an IFS06 can be moved up and down to fit for heights of DRHs.
The IFS06 supports at least three DRHs when the ambient temperature is higher than or equal to the lowest operating temperature of the DRH and at least 5°C (41°F) lower than the highest operating temperature of the DRH. The IFS06 supports a maximum of six DRHs when the ambient temperature is higher than or equal to the lowest operating temperature of the DRH and at least 10°C (50°F) lower than the highest operating temperature of the DRH.

The recommended clearance ensures normal running and provides an appropriate space for operation and maintenance (OM). If there is sufficient space, leave the recommended clearance after installing the equipment.
The minimum clearance ensures normal running and heat dissipation, but OM activities such as checking indicator status and opening the cabling cavity cannot be properly conducted. If the installation space is restricted, leave the minimum clearance after installing the equipment.

Figure 3-21 Minimum clearance for a single DRH
This section describes the recommended and minimum clearances for three or more DRHs.
The recommended clearances ensure normal running and provide an appropriate space for operation and maintenance (OM). If there is sufficient space, retain the recommended clearances.
The minimum clearances ensure normal running and heat dissipation but do not allow OM activities such as checking indicator status and opening the cabling cavity. If the installation space is insufficient, retain the minimum clearances after the installation.
