Installation and Operating Instructions
5 MOUNTING THE SRF
Before mounting the SRF, refer to Table 3 (weights and
dimensions on last page of this manual) which provides
dimensions and unit weights. Ensure that appropriate lifting
equipment is used when installing the larger SRFs. When
installing the SRF, consideration should be given to future
service needs. Ensure that clear view of the status indicators
is provided. The SRFs should be mounted away from other
electrical apparatus (300mm minimum) and in a position that
avoids close proximity to combustible materials.
The SRFs are designed to be wall mounted. Mounting brackets
(as shown in Figure 7) are supplied. The internal backplane may
be removed to facilitate wall mounting. Carefully disconnect the
wiring going to the front door LED before removing backplane.
The cabling and upstream over-current protection requirements
and all instructions provided in this manual, should be taken into
consideration before mounting the SRF.
To preserve the IP rating, SRF units from 63A to 250 A must
be installed in accordance with figure 9 and section 6.2.
• Larger SRF units from 500A to 800A are ventilated and
should be mounted in a dust and moisture-free, ventilated
environment.
• All SRFs should be installed in a dry, well-ventilated area.
Avoid sites subject to moisture ingress.
• SRFs are not intended for use in harsh or corrosive
environments.
Where the SRF is to be enclosed in a switch board cubicle,
models are available without the enclosure. These backplane
units are denoted by the model number suffix 'BP '.
