The device is designed for panel mounting. A square cutout of approximately 92.0 mm x 92.0 mm (3.62 in x 3.62 in) is required. The mounting mechanism uses clips or screws, with a recommended gap of 1-6 mm (0.04 - 0.25 in) for installation.
Wiring
The 9410DC meter supports various wiring configurations for power, voltage, current, and communication.
Control Power
Input voltage ranges:
- AC at 50/60 Hz ± 10%: 90 to 415 V ± 10%
- AC at 400 Hz: 90 to 120 V ± 10%
- DC: 120 to 300 V DC ± 10%
Fuse Requirements: Use 2 A fuses. L1 and L2 are non-polarized. If using an AC power supply with neutral, connect neutral to the meter's L2 terminal. Always use a fuse on L1. Fuse L2 when connecting an ungrounded neutral to the control power. If using a control power transformer, fuse both primary and secondary sides.
