Key Features & Installation Notes

As a plate drive version (H-frame option), the 22B-D1P4H204 weighs approximately 1.41 kg (3.1 lbs) due to its compact construction without an integral heatsink. It must be mounted directly onto an external heat-dissipating surface. It supports DIN-rail or flange mounting for enclosure space savings and allows zero-stacking in ambient temperatures up to 40°C. Built-in protection includes a relay pre-charge circuit to control inrush current and a removable MOV jumper for compatibility with ungrounded distribution systems.

Frequently Asked Questions (FAQs)

Q1: What does the "Plate Drive" enclosure design mean for installation?
A1: It lacks an internal heatsink, requiring direct attachment to an external metallic heatsink or cabinet surface to dissipate operating heat properly.

Q2: Can the 22B-D1P4H204 be used on ungrounded electrical systems?
A2: Yes, it features a removable MOV jumper to ground, enabling safe operation on ungrounded or IT distribution networks.

Q3: Does this drive include built-in dynamic braking capability?
A3: Yes, it includes an integral dynamic braking transistor, requiring only an external resistor for high-inertia stopping applications.
