How To Replace the Fuses
To replace the fuses:
1. Select the proper fuses.
All units have two fuses installed to
fuse both sides
of the line. The fuse values, marked
on the rear panel, are:
•
100 to 120 VAC = 0.63 Amperes Time-Lag Type
•
200 to 240 VAC = 0.315 Amperes Time-Lag Type
Refer to Table 36 for a description of the fuses. To change the line voltage selection,
refer to
How To Change the Line Voltage Selection,
page 82.

Note
The fuses are IEC rated (where the name plate value is the expected
current
carrying
rating) and not UL or CSA rated (where the name plate
value is nearl
the current
blowing
ratin
). Use of UL or CSA rated fuses
will cause unnecessary blowing at high loads.
Appropriate replacement fuses include:
•
Bussmann GDC-T315 mA or equivalent for the 0.315 A fuse
•
Bussmann GDC-T630 mA or equivalent for the 0.63 A fuse
