1. Select a 3‐wire (plus ground) power cable rated for the maximum
amperage required by the melter. Ensure that the power cable meets
applicable electrical codes and standards. Table E‐3 lists the maximum
amperages (per line) for 400/480 volt ProBlue adhesive melters.

WARNING! Risk of electrocution! ProBlue melters must be installed with a
lockable power disconnect switch that completely de‐energizes the melter by
isolating it from its power source. Failure to de‐energize the melter when
required can result in personal injury, including death.
WARNING! Risk of electrical shock or short circuit. Use rigid or flexible
conduit or an appropriately sized strain relief to protect the power cable from
the sharp edge of the conduit knockout.
2. Route the power cable between the power disconnect switch and the
transformer. Secure the power cable to the transformer sub‐base using
the cable clamp provided in the installation kit (P/N 331872).
See Figure E‐6.
3. Flip the splash shield away from the terminal block, and then connect the
power cable to the terminal block (terminals 1, 2, and 3).
4. Connect the power cable ground lead to the ground lug that is located on
the transformer chassis.
5. Re‐connect the ground lead on the transformer chassis to the ground
post on the sub‐base.
6. Replace the transformer lid.
