- 4 - NetWaySP41BT Series Installation Guide
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/ANSI, and with all local codes
and authorities having jurisdiction. All units should be installed by a trained service personnel.
Mounting Instructions:
NetWaySP41BTB:
1. Mount board in the desired location/enclosure
with hardware supplied.
Note: For proper earth ground connections on
NetWaySP41BTB fasten metal spacers (provided) to
threaded studs at indicated board mounting holes
(shown on the right). This is recommended for better
environmental immunity.
2. Connect external 48V-56V UL Listed ITE power power source to terminal marked [+] and [–], carefully
observing correct polarity (Fig. 2, pg. 6).
NetWaySP41BTWPN/NetWaySP41BTWP/NetWaySP41BTWPX:
1. Remove backplane from enclosure prior to drilling. Do not discard hardware.
Note: Make sure that hardware will not interfere with components of the circuit board.
2. Mark and drill desired inlets on the enclosure to facilitate wiring. Maximum NEMA type 4X rated fittings
to be used are 0.5”. Follow manufacturer’s specifications for the appropriate size opening.
Note: Inlets for conduit fittings should only be made on the bottom of the enclosure.
To facilitate wire entry utilize weather-tight NEMA rated connectors (supplied), bushings, and cable.
3. Clean out the inside of enclosure before remounting circuit boards/backplane.
4. NetWaySP41BTWPN: Connect external 48V-56V UL Listed ITE power power source to terminal marked
[+] and [–], carefully observing correct polarity (Fig. 2, pg. 6).
5. Mounting NEMA4/4X rated enclosure (Enclosure Dimensions, pg. 11-12):
Wall mount: Mount unit in desired location. Mark and drill holes to line up with the top and bottom
hole of the enclosure flange. Secure enclosure with appropriate fasteners (e. g. screws
and anchors; bolts and locking nuts, etc.) that are compatible with mounting surface and
are of sufficient length/construction to ensure a secure mount (Fig. 4, pg. 8).
Pole Mount: Refer to Fig. 5 - 9, pg. 8.
6. Mount backplane in enclosure with hardware.
NetWaySP41BTX:
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two (2) upper fasteners and screws in the wall with the screw heads protruding.
Place the enclosure’s upper keyholes over the two (2) upper screws; level and secure. Mark the position of
the lower two (2) holes. Remove the enclosure. Drill the lower holes and install two fasteners. Place the
enclosure’s upper keyholes over the two (2) upper screws. Install the two (2) lower screws and make sure
to tighten all screws (Enclosure Dimensions, pg. 9). Secure enclosure to earth ground.
NetWaySP41BTPL:
1. Mount backplane in the desired enclosure with hardware supplied (Backplane Dimensions, pg. 10).
Power Connection:
For NetWaySP41BTWP, NetWaySP41BTWPX, NetWaySP41BTX, and NetWaySP41BTPL:
1. Secure cabinet to earth ground. Connect AC power from overcurrent protective device circuit breaker
(20A @ 115VAC, 60Hz, 16A @ 230VAC, 50/60Hz) to the terminals marked [L, N] on power supply board
(Fig. 3, pg. 7). Use 14AWG or larger for all power connections (Battery, DC output, AC input).
Connect ground lug to earth or green branch wire (12AWG min.).
Keep power-limited wiring separate from non power-limited wiring by utilizing separate knockouts/
inlets. Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing
equipment. There are no user serviceable parts inside. Refer installation and servicing to qualified
service personnel.
