DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR
ARC FLASH
When installing transformers (regardless of the
location) the installing contractor is responsible
for the proper installation in accordance with the
attached instructions and all applicable codes and
standards (including Seismic). Failure to do so
will result in serious personal injury or death and
property damage.
Figure 1.
Encapsulated Low Voltage Transformer
Encapsulated transformers are available with a number of
accessories to facilitate installation. Consult your local distributor
for the purchase of any of the items accessories that are stocked in
inventory. Some frequently used accessories include:
1) Breather drain plugs are strongly recommended for type
4/4X enclosures when there is temperature variations (i.e.
night/day operations) and when condensation may be present.
When breather drain is mounted at the bottom of enclosure,
this unique design provides effective drainage of moisture due
to condensation from within enclosure without compromising
type 4/4X integrity.
***Please ensure the drain plug is installed as per Fig. 1.
Ensure the drain holes are air cleaned from any obstruction
before insalling.
2) Connectors (Lugs)
Connectors for the installation of dry-type transformers
are readily available. These connectors are suitable for use with
either copper or aluminum cables.
Connectors should be sized, installed and connected
to cables in accordance with your local electrical code
requirements using the best practices to ensure safe and
reliable operation. Cable surfaces should be properly cleaned
and electrical compound should be used for all connections.
Selecting Connectors
a) Determine the primary current for the required
transformer from the Appendix A.
b) Similarly, determine the secondary current rating for the
transformer from Appendix A.
