Power Supply - Rack-Mount SignalHawk
AC Power Connector
The AC Power connector provides operating power for the Rack-Mount
SignalHawk. The AC power supply cord is also the line disconnect
device for this product. Use the supplied AC power cord or an approved
power cord to connect to the Rack-Mount SignalHawk, such as domestic
type SVT, 300 VAC, 18 AWG, 10 A, 3 conductor (including ground) or
international type H05VV-F, 300 VAC, 1.00 mm, 10 A, 3 conductor
(including ground).
Note:
The Rack-Mount SignalHawk is shipped from the
factory configured for 110VAC operation, 2-pole fuse (fused line
and neutral). If the Rack-Mount SignalHawk will be installed
with 220VAC supply, follow these instructions:
1. Remove the fuse drawer from the power entry module on the rear
of the unit.
2. Remove fuses from drawer & set aside.
Note:
There are two different fuse drawers supplied with
the Rack-Mount SignalHawk. One is a 2-pole fuse tray (fuse on
both lines) the other is a single fuse tray (line fuse, shorting bar
on neutral). Check with local regulations to determine whether
single or dual pole fuse protection is required.
3. Install one or both fuses into the appropriate fuse drawer:
z 110VAC operation: 5x20mm SLO BLO 1.25A
z 220VAC operation: 5x20mm SLO BLO 0.63A
4. Replace fuse drawer into the power entry module
5. Insert AC power cord into the IEC receptacle on the power entry
module.
DC Supply
The Rack-Mount SignalHawk can also be powered by a direct DC volt-
age wired into the terminal lugs on the rear of the unit. This is useful
if the installation site has DC power readily available or it can be con-
nected in addition to the AC power if the DC source is part of a battery
back-up system. There are two separate DC power inputs on the ter-
minal connector. The combination of the two allows a wide range of
DC voltage sources. Refer to the specifications page for voltage range
and current requirements.
Note:
Ensure proper polarity is observed on the DC supply
and input voltage is connected to the correct pair of terminal lugs.
