Electrical Connections
A POWERdrive LED driver has 16 color-coded connectors (3 for mains, 8 for LED outputs, 3 for DMX, and 2 for LEDcode /
NTC), see Figure 1. Each LED load must have a dedicated (+) and (-) connection to the POWERdrive LED driver. To facilitate
wiring, the LED output (+) connectors are color-coded, with Red, Red, Green, Blue, and Yellow corresponding to LED
outputs 1, 2, 3, and 4, respectively.
The acceptable wire cross section for each connection type is listed in Table 1. Wire sizes outside this range may damage
the connector pole or prevent the wire from making a secure mechanical and/or electrical connection. Smaller wire sizes
can be accommodated in combination with a ferrule, see Figure 2. Insertion of multiple loose wires into a driver terminal
may result in unacceptable mechanical or electrical contact to both wires. Instead, consider using a twin cable ferrule to
connect multiple small wires (e.g. DMX wiring) together for insertion into a connector pole.

connection to the POWERdrive LED driver. The 4 LED outputs that
can be programmed to be controlled

Table 1: Acceptable wire cross section for the various connection types to a POWERdrive LED driver. Note that the
acceptable wire cross section for LED output and LEDcode/NTC are restricted for POWERdrive 50SA-M4Z0X drivers so
the plastic endcap can exert enough clamping force onto the mains cabling.
