Hamilton Sundstrand Company ACT2000 - Manual (Page 17)

1.4 Electrical Connections
The ACT2000 is suitable for use in hazardous locations. See the General
Specification Summary in Section 1.2 for certifications. Ensure compliance
with the factory recommendations, and that wiring is in accordance with
local requirements.
WARNING:
94/9/EC (ATEX) Compliance – Special Conditions for Safe Use:
Two special factory-sealed unions are mounted on the equipment to
ensure the electrical connection to the network and to provide the
feedback signal to the user.
The installation of these devices and the final connections to the
conduit shall comply with the requirements of the European
standards.
Ground Connection
The case of the ACT2000 features a threaded hole (0.250-20 UNC-2B
female thread) that is dedicated for the ground connection. This hole has
been left unpainted and uncoated to ensure a good electrical contact. On
the pin-mounted version (ACT2000-590P), this threaded hole is located
on the underside of the unit below the identification plate (see Figure 1-3).
On the flange-mounted version (ACT2000-200F), this threaded hole is
located on the clevis end of the unit (see Figure 1-2). Use a screw with a
0.250-20 UNC-2A thread to connect the case of the ACT2000 to the
same ground plane as the user’s controller.
Power Connections
The ACT2000 operates on a 120VDC (nominal), user-provided input
voltage, which is supplied to the unit through the integral four-wire power
harness. The length of the power harness is 90 inches. See Table 1-1 for
the wire list for the ACT2000 power harness. See Figure 1-5 for the
ACT2000 system power wiring diagram. See Figure 1-6 for a typical
power connection with a power supply. See Figure 1-7 for a typical power
connection with a battery.
