Replace the fuse(s) only with the correct value and type of fuse. See Table 0-2 and the text following it
for fuse values and type descriptions.
6) Replace the fuse holder (with the correct fuses) in the AC input module. The end with four metal
contacts goes into the AC-line connector first. Both orientations that fit work identically.
7) Close the cover of the AC input module. It should snap into place.
Ventilation
Your Reference 30k Booster was designed to operate at ambient temperatures between 0

C and 40

C.
Be careful when operating the Reference 30k Booster in an enclosed space (such as an enclosed relay rack or
NEMA enclosure).
Caution:
The temperature within the enclosure must not exceed 40

C. You may need to
provide ventilation holes or even forced air cooling for the enclosure if excessive temperature-rise occurs.
Caution:
The AC power fuses are important components for safe operation of the
Reference 30k Booster. Never replace the fuses with incorrect values or types, or in any way circumvent
the fuse action. If your Reference 30k Booster routinely blows the AC-line fuses, it could indicate a serious
problem with the Reference 30k Booster. Contact Gamry Instruments or your local sales representative for
repair information.
