Power Supply Fusing - Aerotech DR300 Operation & Technical Manual

Set Up
2.3.
The entire chassis is protected by CB1, a combination power switch and circuit breaker.
There will be either a 5A breaker or an 10A breaker (see section 3.4.). The Bus Power
Supplies are individually fused on the AC side of the circuit by F1 – F4 (see section 4.5.).
The fuses are located inside the DR300 on a fuse block mounted to the left side on the
bottom of the DR300 near the transformers. The right fuse is for Bus supply #1 and the
left fuse is for Bus supply #2. The value of these fuses can be found on the DR300 system
wiring drawing (see Chapter 4, Table 4-3).
WARNING
Besides the two Bus power supplies the DR300 contains a power supply that provides +5,
+12, -12 and +24 VDC. This supply is located on the right side of the DR300 and is not
user serviceable. Several re-settable fuses are located on the Rear Panel Interface board
for external +5V usage. These fuses do not require replacement, but are reset by turning
off power for approximately 30 seconds (remove shorts or overloads from +5V before
turning power on).
