J25 Hydraulic Power Unit Connection
Connector J25 HPU controls the hydraulic power unit (HPU).
• The connector provides 24 V logic signals to control the HPU.
• The connector may be connected directly to a Model 505 or 24
PLC HPU or to a Model 493.07 HPU Converter Box, which allows
any MTS HPU to be connected to the chassis with the following
exceptions:
– 506.52 - .92 HPUs (24 volt, PLC compatible)
– All Series 505 HPUs
The converter box is used with other configurations, see
“Hydraulic Configurations” on page 221 for more information.
Control voltages for hydraulic power units vary between models.
The HPU interface between the Model 493.42 System I/O board and an
HPU is 24 volt logic signals. Connecting J25 to a non-compliant HPU
can damage the module.
DO NOT connect 24 V DC relay circuitry or 115 V AC circuitry to connector
J25 on the Model 493.42 System I/O board.
Cable specification The J25 HPU and J51 Box In connectors are 15 pin type D male
connectors.
• 15 contact type D female EMI connector.
• Cable—24 AWG, 10 conductor with braided shield with drain wire
connected to metallized plastic backshell to the chassis.
Jumper plug required If connector J25 HPU is not used, you must install a jumper plug to
maintain the integrity of the interlocks. Use jumper plug 39-713-301E
or jumper pins: 1–7, 2–3–5, 6–9, 8–10–11–12, 6-9.
