Installation
Before installing your power supply, you will need to determine the type of supply
units you have. To do this:
1.
Locate the assembly number sticker on the back of the power supply frame.
Systems with Pioneer power units will have power supply frames numbered
098901-00 or -01. Systems with Todd power units will have frames labeled
098901-03.
2.
Remove the back covers on the left and right sides of the primary and/or
redundant power supply frames. Leave the covers off for installation purposes
later.
You may distinguish between a Todd supply and a Pioneer supply as follows:
Viewed from the front, both +5 V and Multi-Output Pioneer units are each
about 5 inches wide, and each has a 4 1/2 inch diameter fan.
The Todd +5 V unit (on the left) is about 3 1/2 inches wide. The Multi-Output
supply is slightly narrower. Each supply has two cooling fans.
From the rear, the Todd and P5 Volt units can also be identified by the
arrangement of the large power lugs on the rear of the supplies. They are
arranged horizontally on the Pioneer supplies, and diagonally on the Todd
supplies. For clarity however, both types of supplies will be illustrated in this
manual in most cases.
Model 4000-2A/B Only–Determining 110V or 220V AC Operation
If you have Pioneer power supply units, you must operate at 220Vac.
If you have a Model 4000-2A/B with Todd power supply units that are capable of
operating at 110Vac, there will be a label on the rear plate of the power supply
frame to indicate this. The recommended operating voltage is 220Vac.
If it is desired to operate on a 100 to 120 Vac circuit, first check the rear plate on the
Frame Power Supply to see that it indicates this capability.
For 110 Vac nominal operation, the supplied 10 AWG power cord must be
replaced with 6 AWG wiring. It is recommended that this 6 AWG wiring be
connected into the power supply frame directly from a junction box. This should
be a dedicated circuit fused for 40A overload protection.
To rewire the Frame Power Supply for nominal 110 Vac operation, proceed as
follows:
1.
Make sure that all power is disconnected (from both supplies in a redundant
system).
2.
Remove the left and right rear covers from the primary and redundant (if
installing) power supply frames if you have not already done so, and then
remove the center rear cover plate from the power supply.
