WIRING AND POWER

WIRING 115VAC OR 208/230VAC
POWER
●
Verify AC power supply wires and low voltage
accessory wires run through separate conduits. The
higher voltage to the AC power supply may cause
interference and anomalies in SlideSmart CNX
operation if the high voltage wires are routed through
the same conduit as the low voltage wires.
●
Maximum gate operator current draw is 7.5 Amps on
a dedicated 115VAC circuit (20A dedicated circuit is
recommended).
●
Maximum gate operator current draw is 4 Amps on a
dedicated 208/230VAC circuit (20A dedicated circuit is
recommended).
●
Make sure proper wire gauge is used for the length of
the wire run. The following tables show the maximum
allowable wire run from the power source to the
operator for various wire sizes.

NOTICE
Table 1 and Table 2 assume a dedicated circuit with
an accessory power load up to 2A. Additional loads
require that the wire size be increased or the distance
of the run be decreased.

Operators are factory set for incoming power of 115VAC.
If 208/230VAC, change the voltage switch on the power
supply to 230VAC with a flathead screwdriver (Figure 24
and Figure 25).

Always connect electrical power and ground the operator
in accordance with the NFPA 780 & NEC, Article 430 and
Article 250. Research and adhere to other local codes
that may apply.
