Maximum Output Loads
Note in later Coldroom panel hardware revisions, Revision 2, the Compressor/LLV, Fans and Defrost ratings have been revised. Please
view the appropriate listing, shown below, depending on the hardware revision in use. A visual inspection of the Coldroom panel must
take place to determine the hardware revision. A label is affixed alongside the relay outputs highlighting the current rating in Amps.
Note in Revision 2 the Compressor/LLV and Defrost MCB or Fuse can be interchanged to allow the higher rated MCB or Fuse to be used
on the Compressor/LLV relay output and the lower rated MCB or fuse to be used on the Fans relay output. Please see Appendix 1
