Fuse Information

WARNING: To reduce the risk of fire, replace fuses only with the same type

and rating.

Each unit uses a universal switching power supply that handles the full range of

nominal mains voltages between 90 and 264 VAC and any frequency between 50 and

60 Hz.

Check Main Fuse

The main fuse rating is T 1A L (1 amp, 250 V, 20 mm, time-lag, low breaking

capacity) for all operating voltages.

WARNING: The power to the unit must be off when the following steps are

performed. Ensure that the main power cable to the unit is not connected to a

power source.

To inspect or replace the main fuse:

1. Open the fuse compartment door in the AC power input housing with a small flat-

blade screwdriver. (See the following figure.)

2. Check that the fuse in the active (lower) fuse carrier is the correct rating. The fuse

carrier must be inserted into the compartment with the orientation shown in the

following figure. Do not force the carrier into the compartment or both could be

damaged.

3. Snap the fuse compartment door closed.
