11 The PIM Evaluation board is equipped with a 3x470µF capacitance.
Along with the Board, as a side-part, a 3300µF capacitor is included in
the kit. It is up to the user to un-mount and/or mount the capacitance
actually needed. For information about hold-up capacitance
recommendations, please see the technical specification for the PIM
product.
When connecting the 3300µF capacitor attach “-“connector of the
capacitor (see a, Figure 2) to the “-“ connection of the board (see b,
Figure 2). Soldering is required.

2.2 Power Supply
Power the board by connecting 36-75 V DC power to the “+IN A” and –IN A”
and/or “+IN B” and “-IN B” connectors (see 1a-1d, Figure 1). Enable switches A
and B should be in OFF position (see 7, Figure 1).
2.3 Management Power
With an external power supply PIM 4820’s management power (see 3c in Figure
1) can handle larger loads, for more information see the technical specification for
the PIM product.
The external power supply shall be connected between +IN2 and GND (see 3a-
3b, Figure 1). it shall be at least 1.5 V above the +OUT2 voltage (see 3c, Figure
1) and max 14.4 V.

5 Address and Voltage Pin-strap Resistors
This section describes the locations of the address and voltage pin-strap resistors
and the resistors for hold up and +OUT2 voltage adjustments. For exact resistor
values see the technical specification for the PIM product.
5.1 Address pin-strapresistors
Figure 5 shows the positions of the address pin-strap resistors for the different
PIM products. R2 and R3 are positions of the address pin-strap resistors for
PIM 4820. R29 is the position of the address pin-strap resistors for
PIM 4328.

6 Fuses
The DC input to the board is protected by fuses. Figure 9 shows the positions (a-
d) of the fuses. In each position there are two 12 A fuses mounted in parallel.
Figure 9. The positions of the fuses.
7 Isolation
The board is equipped with 0 Ohm resistors tying SHELF_GND and GND/DGND
together. If 2250 V isolation is desired the resistors R33-R35 have to be removed.
Figure 10 shows the positions of the resistors R33-R35
