Control voltages for hydraulic power units vary between models
The HPU interface between the Model 494.42 System I/O board and an HPU
is 24-volt logic signals. Connecting J25 to a non-compliant HPU can damage
the board.
Do not connect 24 V DC relay circuitry or 115 V AC circuitry to connector J25 on
the Model 494.42 System I/O board.
Cable specification To maintain EMC compliance, J25 HPU cables must comply with the following
specifications:
Connector—15-contact, type-D, female EMI connector.
Backshell–EMI metallized plastic or metal.
Cable—22 AWG, 10-conductor with braided shield with the shield connected to
metallized plastic or metal 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 PN 039-713-301 or jumper pins 1–7,
2–3–5, 6–9, 8–10–11–12.
