FIELD POWER WIRING
1. TO AVOID EQUIPMENT DAMAGE
DO NOT CONNECT POWER
SUPPLY DIRECTLY TO ELEMENTS!!!
2. L1, L2, Ground to be field wired
3. Super 1E 240/1 models are not sup-
plied with internal fusing.
4. All Drawings are for illustrative
purposes only. Consult with
qualified licensed electrician
for electrical installation.
Models MS90E – MS400E
(single phase wiring shown)
Models MSSUPER1E - 3E
(single phase wiring shown)
ELECTRICAL
All electrical wiring to be installed by
a qualified licensed electrician in accordance with
National Electrical Code and local electrical code.
POWER WIRING
See “Field Power Wiring” Diagrams (below)
1. Check power voltage. Use 240V rated unit when supply
is greater than 208V. (Most homes have 240V, 1PH
service). Use 208V rated unit for 208V power.
2. Use minimum 90˚ C/300V rated insulated copper
conductors only, sized in accordance with National
Electrical Code and local electrical code for the current
in Ampere Chart. If allowed by codes, NM cable may
require a larger wire size than as listed on the chart.
3. Connect suitably sized equipment grounding wire to
ground terminal provided.
4. Install a separate circuit breaker between supply and
unit. Provide a power supply disconnect within sight
of the steam generator or one that is capable of being
locked in the open position.
5. For single phase units, use two-wire supply source and
equipment grounding wire. Neutral (white) wire is not
required.
