INSTALLATION OF IP00 (OEM KIT) IN A CABINET
6.1
Mounting
The HRVS-DN must be mounted vertically. Allow sufficient space for suitable airflow above and below the
HRVS-DN.
Verify that minimum clearances specified in the applicable codes/standards are applied.
In addition, when glass epoxy of any-type or thickness is utilized within the cabinet assembly, minimum
clearances specified in the applicable codes/standards are not lowered.
Notes:
(1) Do not mount the HRVS-DN near heat sources.
(2) Cabinet internal temperature should not exceed 50°C. Refer to section
6.2 page 40 for heat dissipation of
the soft starter during operation.
(3) Protect the HRVS-DN from dust and corrosive atmospheres.
(4) In order to perform low voltage test, certain provisions should be applied:
a. When a step-down transformer provides the Control Voltage, allow for supply of Control
Voltage from external source
b. In HRVS-DN up to 6.6kV, allow sufficient access to the rear side of the EPT-Tx (to allow low
voltage Test Harness connection).
c. To allow phase disassembly, provide for the following assembly precautions (Refer to
Figure 14
)
for:
i. Horizontal support bar (this bar is mounted on the inner side of the M.V. door).
ii. Two support rods 850mm length with M12 thread.
For phase disassembly, the horizontal support bar is mounted at the front of the cabinet,
bracing the support rods.
